IBM New Server Information

BANGALORE: IBM on Monday launched globally its next generation Power server, the server that caters to that intermediary (Unix) segment between the powerful mainframe computers and the lower end X86 based servers, and on which a lot of corporate India’s applications run.
Called Power7, the server is said to be a big leap over Power6 that came in 2007. Alok Ohrie, director for the systems and technology group in IBM India, claimed it would be a game changer especially for India, which is a strong Unix market.
Power 7 is said to have four times the processing capability of P6, as also of competing platforms from Oracle/Sun and HP/Intel, and 2 to 3 times the energy efficiency of P6.
“What that means is, you can process and analyse millions of more transactions in the same time as previous generations of systems did, and it therefore significantly improves a company’s decision making capability,” Ohrie said.
The Power range caters to small and large enterprises, but Ohrie expects companies in banking and finance, telecom and public sector to be among the early adopters of P7.
“These are the fastest growing segments of industry, and their computing capacities are peaking. In telecom, for instance, once number portability comes in, it will become critical for operators to analyse and understand customers better in order to retain them. And that will require a lot more processing power,” he said.
Higher processing power often comes at a higher cost because of either more power consumption or because of bigger chips or systems that take up more space (adding to real estate cost). But in the case of P7, IBM claims the design is such that neither rises significantly, and hence the total cost of operation actually comes down substantially in comparison to older Unix systems.
The P7 launch is said to have been advanced, and, according to an analyst writing in the industry publication The Register, IBM “wanted to get out in front of a whole lot of processor and systems launches that are expected between now and the summer”.
He goes on to write: “The machines announced today are clearly aimed at blunting the attack of midrange X64, Itanium (from Intel-HP ), and Sparc (Sun) servers as well as some bigger boxes that are going to start creeping up into the power class of the current top-end Power6-based Power 595 machine.”
In India, IBM was No.1 in the non-x 86 Unix server market with a 38.87% market share in terms of factory revenue for the first half of 2009, according to research firm IDC. The marketshare has grown compared to that in the previous two years. With P7, IBM may be able to further consolidate that position.

P7’s India connections
IBM’s Systems & Technology Lab in India is said to have made significant contributions to the P7 programme, developing and enabling key hardware and software functions. “Major contributions were in terms of hardware design and verification of various components of P7 processor, platform bring-up, enabling soft functions through Power Firmware, AIX and Linux, hardware systems test and platform management,” IBM said. Another India connection is that the programme is led by Satya Sharma, an IBM Fellow and the CTO for the Power systems division. Sharma is said to have started his career in India. IBM Fellow is the Big Blue’s highest technical honour and Fellows are selected for sustained and distinguished technical achievements in engineering, programming and technology

Server-side scripting

Server-side scripting is a web server technology in which a user's request is fulfilled by running a script directly on the web server to generate dynamic web pages. It is usually used to provide interactive web sites that interface to databases or other data stores. This is different from client-side scripting where scripts are run by the viewing web browser, usually in JavaScript. The primary advantage to server-side scripting is the ability to highly customize the response based on the user's requirements, access rights, or queries into data stores.

When the server serves data in a commonly used manner, for example according to the HTTP or FTP protocols, users may have their choice of a number of client programs (most modern web browsers can request and receive data using both of those protocols). In the case of more specialized applications, programmers may write their own server, client, and communications protocol, that can only be used with one another.

Programs that run on a user's local computer without ever sending or receiving data over a network are not considered clients, and so the operations of such programs would not be considered client-side operations.

Mainframe Computer

mainframe
A very large and expensive computer capable of supporting hundreds, or even thousands, of users simultaneously. In the hierarchy that starts with a simple microprocessor (in watches, for example) at the bottom and moves to supercomputers at the top, mainframes are just below supercomputers. In some ways, mainframes are more powerful than supercomputers because they support more simultaneous programs. But supercomputers can execute a single program faster than a mainframe. The distinction between small mainframes and minicomputers is vague, depending really on how the manufacturer wants to market its machines

The long wait is over. On July 22, IBM announced the next generation of mainframe processors. IBM officially calls the new processor the zEnterprise 196, or z196, machine type 2817. The new machine boasts the usual increases in size and performance as well as something new.

ZEnterprise processor details
A zEnterprise 196 cabinet can hold four books, each book containing six quad-core processors and up to 786 GB of memory with four levels of cache. The biggest and baddest zEnterprise sports 96 cores, of which 80 are available to the customer.

As with all the previous generations, the z Enterprise 196 is faster. IBM says the microprocessors run at 5.2 GHz as opposed to the z10's 4.4 GHz. This translates to a 40% capacity boost over a z10 with the same number of engines, while a fully loaded z196 contains 60% more capacity than a fully tricked-out z10. Your mileage, of course, will vary.

It sounds like some of the internal pipelining was also changed, as the data sheet claims there are new instruction execution sequences for better performance. For the application folks, IBM has compilers with optimization options for the new hardware, some of them presumably taking advantage o

CPU Shroud Assembly for Dell PowerEdge SC1420 Server

Highlights
•This product will ship with the following component parts:
Component Part Number Description
0N399 GRMT,MTG,RBR,FAN,TSMT
P2780 FAN,92X38MM,12V,HISPD,TEJAS
W1702 SHRD,PLSTC,FAN,TMD,SECONDARY
Overview
The various components of a computer system such as the chipset, the graphics card and the hard drive can produce a large amount of heat while operating. This large amount of heat may be harmful for the proper functioning of the system. The heat sinks and the fans are responsible for dissipating this heat and maintaining the safe temperature limits.
The most important factor which determines the selection of Heatsink Assembly is the processor type and its speed. Different processors have different operating temperatures. Higher the speed of the processor, the better the heat sink and fan need to be. Similarly, the type of processor also determines what heat sink would go with it. The chassis type is also important as it defines the housing of the heat sink assembly and compatibility with the system.
In order to buy the right heat sink / fan for your system, we recommend that you use the Service Tag look up feature in the Parts For Your Dell™ tool. This will allow us to identify the processor type and speed of your system and select compatible Heat Sink products for it.
Please note that some of our replacement products are provided as kits or assemblies. These kits may contain additional parts required for installation; these parts will be listed separately as 'Component Parts' in the Highlights section of this page. In case a product is not sold as a kit or assembly, it may require complementary parts for ease of installation.

CPU Shroud Assembly for Dell PowerEdge SC1420 Server

Assembling a computer from components

Assembling the 2005.05.14 standard workstation
The instructions below are for the 2004.10.10 standard workstation.
The 2005.05.14 standard workstation has the following changes:
The UATA hard drive (and cable) have been replaced by a SATA hard drive (cable included with the motherboard). Effects on assembly: the hard drive uses a different cable from the one shown below, and plugs into a different spot on the motherboard.
The Zalman fan has been replaced by a three-speed Antec fan with a 4-pin power connector. Effects on assembly: the fan plugs into main power instead of the motherboard; the power-supply fan plugs into the motherboard.
The video card and DVD-ROM drive are different. Effects on assembly: none, but slightly different pictures.
The 2005.08.23 standard workstation has more changes. There turns out to be a serious bug in the motherboard BIOS in the 2005.08.23 workstation, and fixing that bug requires the following extra steps once the computer has beeped:
On a working computer, download the file A8V-ASUS-0213.ROM from the Asus A8V download page. This file has MD5 checksum 9c44e207cb3e37a6dc797aa6e1b99f5e.
On a working computer, rename the file as A8VB.ROM and burn that file to a CD.
On the standard workstation, as soon as the initial boot screen appears, press Alt-F2 to enter the BIOS EZ Flash utility, and then insert the CD. The EZ Flash utility will read A8VB.ROM from CD, erase the system's BIOS, and copy A8VB.ROM to the system's BIOS; don't turn the computer off while this is happening!
After reboot, don't worry about the bad-checksum message; simply press F2 to continue.
Other changes in the 2005.08.23 standard workstation are not reflected here yet.
Assembling the 2004.10.10 standard workstation
The 2004.10.10 standard workstation is a very nice x86 (Intel-compatible) computer: solid, extremely fast, and reasonably inexpensive. I have a separate page explaining how to buy the components of the standard workstation. This page explains how to assemble those components into a working computer.
Some of these instructions, and most of the pictures, are specific to the 2004.10.10 standard workstation. If you're using any different components, you'll have to figure out appropriate modifications to the instructions.
Unpack the computer case. Discard its plastic wrap. Put on an antistatic wrist strap, and attach it to ground (for example, to the screw on a typical light-switch plate).
Unscrew the big screws on the back of the case. Pull on the side latch to open the case. Take the power cord and the brown box out of the case. Open the brown box to find a bag of screws and brass standoffs:

Plug the USB cable into the motherboard

Plug the reset-switch, power-switch, HDD-LED, speaker, and power-LED connectors into the motherboard, all labels facing upwards:

Plug the USB cable into the motherboard:

Don't worry about the IEEE 1394 (FireWire) cable. Don't worry about the power-supply fan cable. (I didn't realize, when I was selecting components for the standard workstation, that there were only two fan connectors on the motherboard. The next version of the standard workstation will have either a $2 3-pin-to-4-pin converter or a 4-pin case fan.)

Starting now, be very careful not to touch anything inside the case. Power will be flowing into the computer in a moment; if you touch something inside the case, you can electrocute yourself!

Take off the antistatic wrist strap. Turn the case's rear power switch off (0). Plug power into the case. Turn the power switch on (1). Watch the CPU fan, and press the front power button on the case. If the CPU fan doesn't start spinning, turn power off immediately; you have a problem. If the computer doesn't beep within thirty seconds, turn power off; you have a problem. If the CPU fan starts spinning and the computer beeps, turn power off; you have a working computer. Put the side of the case back on.

At this point you can install FreeBSD or Linux on the computer.

Apple's 15-inch 2010 MacBook Pro: More Battery Life Tests, High Res Display Evaluated

Apple is in a position that’s enviable by any consumer facing company. It drums up genuine excitement for nearly every product it launches. Apple has somehow found a way to make something as small as just another processor refresh exciting.

It’s not all smoke and mirrors though. The previous generation unibody MacBook Pro posted some incredible battery life numbers. And two weeks ago Apple paired it with Intel’s Core i5 and i7 mobile CPUs, delivering the sort of desktop-like performance we’ve been waiting for.

Since the release we’ve had the time to answer a few more questions about the new systems. We updated our launch article with Core i5 vs. Core i7 results. But today, in response to many of your requests, we’ve got more battery life results and a full evaluation of the 15-inch MacBook Pro’s display quality. Apple is often the go-to manufacturer for creative professionals; we put our colorimeter on the MacBook Pro to find out if they’re making the right choice.

Dell G2410H Review: A Green 24" LCD

If you haven’t been paying attention lately, energy conservation and being green is the latest and greatest trend sweeping the consumer electronics market. From energy-sipping power supplies to notebooks fabricated using recycled plastics, it’s a trend that’s here to stay.

We've had Dell's energy-sipping G2410H for a while now, and have the complete rundown on just how green the monitor is. At the same time, we've been reworking our display review testbench and have added some things you've always wanted. Check it out!

New HP Value LCDs

This past weekend, HP unveiled three new LCD monitors aiming to be an affordable companion to your computing needs. Available starting May 16, these monitors range in size from 20” to 23” and start at $150 for the 20" model.

All three LCDs offer good contrast ratios (1000:1 typical) and anti-glare (matted) panels, but they trim extras like height-adjustable stands, USB ports, and HDMI in order to keep prices low. There's plenty of competition in the entry-level LCD market, but if the price is right the HP displays are worth a look.

Sceptre X270W-1080P Review: A Value 27" That Delivers

If you’ve been in the market for a large or even midsize LCD display lately, chances are good you’ve seen relatively low-cost offerings from a relative newcomer to our display review section - Sceptre. We saw Sceptre’s 27” LCD at a local wholesale club and on Newegg for an MSRP of $399. Our interest was piqued, and we asked them to send us their flagship. We’ve had it longer than intended - a little over a month - while we revamped our display testbed, but have thoroughly put it through its paces.

How does this relatively inexpensive 27” TN panel-packing display stand up? Well, we were pleasantly surprised.

A New 30" Contender: HP ZR30w Review

Recently, HP’s performance ZR series of LCD displays have attracted quite a bit of attention. We’ve heard your comments and pleas for reviews of the 22” and 24” ZR series of HP displays, and those are still very much forthcoming. But for today, we’re breaking some news with a review and launch announcement of HP’s 30” high performance display refresh - the S-IPS ZR30w. It's HP's latest and greatest flagship, and we've thoroughly reviewed it.

Meet HP's new 30" flagship, the ZR30w

Does this 1+ billion color behemoth capture the 30" crown? Read on and find out!

HP Launches New Consumer LCDs

Following the launch of their budget range of LCDs, HP has now launched some more premium models for those in need of better specifications. There are four new models ranging from 20” to 27” featuring integrated speakers and HP’s BrightView displays, and three of the models include HDMI connectivity. The 27” model in particular boasts a 92% color gamut and 400 nits CCFL backlighting. They are available now from HP with pricing starting at $179.99 for the 20” model up to $459.99 for the 27” model.

ASUS VG236H 23-inch 3D Display Review: 120Hz is the Future

There’s a new segment in the ever changing LCD display market, one that readers have been asking us to take an in-depth look at for a while now - 120 Hz panels. We’ve been playing with ASUS’ newest display, the VG236H. It's a 120Hz, 1080P, 23" 3D enabled display that joins a small but growing demographic of similarly speced LCD displays.

ASUS's new contender definitely impresses, and at a competitive price point. It was my first experience with a 120Hz LCD and NVIDIA's 3D Vision technology. Despite going in as a cautious skeptic, I'm completely sold on both. Read on for our comprehensive review.

Gateway Launches Three LED-backlit Displays

Gateway has launched three new ultra-slim LED-backlit displays. The new displays are part of two new lines - the FHX series which will be available in 21.5” and 24” form factors, and the FHD series which is available just as a 23” model. All three come with 1920x1080 resolution and a (dynamic) contrast ratio of up to 12,000,000:1. All three displays will be available this month starting at $190 for the 21.5” model and $250 for the two larger models.

Apple 27-inch LED Cinema Display Review

I've wanted a higher density, more compact alternative to the 30-inch 2560 x 1600 panels that I've seen for the past 6 years. Apple was the first to intrigue me with the 27-inch iMac, however I didn't need another computer, I just wanted a monitor. Earlier this year we reviewed Dell's U2711, a 27-inch CCFL backlit LCD display with a 2560 x 1440 resolution and loved it.

Recently Apple presented us with an alternative. An LED backlit, 27-inch Cinema Display similar to what's used in the new iMac but without the Mac part. Priced at $999 it's actually $100 cheaper than the Dell, but lacks the input flexibility of the U2711. What Apple does give you is an integrated MagSafe power adapter useful for charging your MacBook Pro in a very sleek package. But how well does it do as a monitor? Read on for our full review.

Server Clash: DELL's Quad Opteron DELL R815 vs HP's DL380 G7 and SGI's Altix UV10

The Quad Opteron Alternative

Servers with the newest Intel six-core Xeon hit the market in April. The fastest six-cores Xeons were able to offer up to twice the performance of six-core Opteron “Istanbul”. The reason for this was that the age of the integer core in AMD's Opteron was starting to show. While the floating point part got a significant overhaul in 2007 with the AMD "Barcelona" quad-core chip, the integer part was a tuned version of the K8, launched back in 2003. This was partly compensated by large improvements in the multi-core performance scaling departement: HT-assist, faster CPU interconnects, larger L3 caches, and so on.

To counter this lower per-core performance, AMD's efforts focused on the "Magny-Cours" MCMs that scaled even better thanks to HT 3.0 and four DDR3 memory controllers. AMD’s twelve-core processors were launched at the end of March 2010, but servers based on these “Magny-Cours” Opterons were hard to find. So for a few months, Intel dominated the midrange and high-end server market. HP and Dell informed us that they would launch the "Magny-Cours" servers in June 2010. That is history now, and server buyers have an alternative again for the ubiquitous Xeon Servers.

AMD’s strategy to make their newest platform attractive is pretty simple: be very generous with cores. For example, you get 12 Opteron cores at 2.1GHz for the price of a six-core Xeon 2.66GHz (See our overview of SKUs). In our previous article, we measured that on average, a dual socket twelve-core Opteron is competitive with a similar Xeon server. It is a pretty muddy picture though: the Opteron wins in some applications, the Xeon wins in others. The extra DDR3 memory channel and the resulting higher bandwidth makes the Opteron the choice for most HPC applications. The Opteron has a small advantage in OLAP databases and the virtualization benchmarks are a neck and neck race. The Xeon wins in applications like rendering, OLTP and ERP, although again with a small margin.

But if the AMD platform really wants to lure away significant numbers of customers, AMD will have to do better than being slightly faster or slightly slower. There are many more Xeon based servers out there, so AMD Opteron based servers have to rise above the crowd. And they did: the “core generosity” didn’t end with offering more cores per socket. All 6100 Opterons are quad socket capable: the price per core stays the same whether you want 12, 24 or 48 cores in your machine. AMD says they have “shattered the 4P tax, making 2P and 4P processors the same price.”

So dual socket Opterons servers are ok, offering competitive performance at a slightly lower price, most of the time. Nice, but not a head turner. The really interesting servers of the AMD platforms should be the quad socket ones. For a small price premium you get twice as many DIMM slots and processors as a dual socket Xeon server. That means that a quad socket Opteron 6100 positions itself as a high-end alternative for a Dual Xeon 5600 server. If we take a quick look at the actual pricing of the large OEMs, the picture becomes very clear.

Compared to the DL380 G7 (72GB) speced above, the Dell R815 offers twice the amount of RAM while offering—theoretically—twice as much performance. The extra DIMM slots pay off: if you want 128GB, the dual Xeon servers have to use the more expensive 8GB DIMMs.

How Configer DHCP Service

Installing the DHCP Service

You can install DHCP either during or after the initial installation of Windows 2000 Server or Advanced Server, although there must be a working DNS in the environment. To validate your DNS server, click Start, click Run, type cmd, press ENTER, type ping friendly name of an existing DNS server in your environment, and then press ENTER. An unsuccessful reply generates an "Unknown Host My DNS server name" message.

To install the DHCP Service on an existing Windows 2000 Server:

Click Start, click Settings, and then click Control Panel.
Double-click Add/Remove Programs, and then click Add/Remove Windows Components.
In the Windows Component Wizard, click Networking Services in the Components box, and then click Details.
Click to select the Dynamic Host Configuration Protocol (DHCP) check box if it is not already selected, and then click OK.
In the Windows Components Wizard, click Next to start Windows 2000 Setup. Insert the Windows 2000 Advanced Server CD-ROM into the CD-ROM drive if you are prompted to do so. Setup copies the DHCP server and tool files to your computer.
When Setup is complete, click Finish.

Configuring the DHCP Service

After you install and start the DHCP service, you must create a scope (a range of valid IP addresses that are available for lease to the DHCP clients). Each DHCP server in your environment should have at least one scope that does not overlap with any other DHCP server scope in your environment. In Windows 2000, DHCP servers within an Active Directory domain environment must be authorized to prevent rogue DHCP servers from coming online and authorizing a DHCP Server.

When you install and configure the DHCP service on a domain controller, the server is typically authorized the first time that you add the server to the DHCP console. However, when you install and configure the DHCP service on a member server, you need to authorize the DHCP server.

Note A stand-alone DHCP server cannot be authorized against an existing Windows Active Directory.

To authorize a DHCP server:

Click Start, click Programs, click Administrative Tools, and then click DHCP.

Note You must be logged on to the server with an account that is a member of the Enterprise Administrators group.
In the console tree of the DHCP snap-in, select the new DHCP server. If there is a red arrow in the bottom-right corner of the server object, the server has not yet been authorized.
Right-click the server, and then click Authorize.
After a few moments, right-click the server again and then click Refresh. The server should display a green arrow in the bottom-right corner to indicate that the server has been authorized.

To create a new scope:

Click Start, click Programs, point to Administrative Tools, and then click DHCP.

Note In the console tree, select the DHCP server on which you want to create the new DHCP scope.
Right-click the server, and then click New Scope. In the New Scope Wizard, click Next, and then type a name and description for the scope. This can be any name that you choose, but it should be descriptive enough to identify the purpose of the scope on your network. For example, you might use Administration Building Client Addresses.
Type the range of addresses that can be leased as part of this scope, for example, a starting IP address of 192.168.100.1 to an ending address of 192.168.100.100. Because these addresses are given to clients, they should all be valid addresses for your network and not currently in use. If you want to use a different subnet mask, type the new subnet mask. Click Next.
Type any IP addresses that you want to exclude from the range you entered. This includes any addresses that may have already been statically assigned to various computers in your organization. Click Next.
Type the number of days, hours, and minutes before an IP address lease from this scope expires. This determines the length of time that a client can hold a leased address without renewing it. Click Next to select Yes, I want to configure these options now, and then extend the wizard to include settings for the most common DHCP options. Click Next.
Type the IP address for the default gateway that should be used by clients that obtain an IP address from this scope. Click Add to place the default gateway address into the list, and then click Next.

Note When DNS servers already exist on your network, type your organization's domain name in Parent domain. Type the name of your DNS server, and then click Resolve to ensure that your DHCP server can contact the DNS server and determine its address. Then click Add to include that server in the list of DNS servers that are assigned to the DHCP clients. Click Next.
Click Yes, I want to activate this scope now, to activate the scope and allow clients to obtain leases from it, and then click Next. Click Finish.

Troubleshooting

Clients are unable to obtain an IP address
If a DHCP client does not have a configured IP address, it generally means that the client has not been able to contact a DHCP server. This is either because of a network problem or because the DHCP server is unavailable. If the DHCP server has started and other clients have been able to obtain a valid address, verify that the client has a valid network connection and that all related client hardware devices (including cables and network adapters) are working properly.
The DHCP server is unavailable
When a DHCP server does not provide leased addresses to clients, it is often because the DHCP service has failed to start. If this is the case, the server may not have been authorized to operate on the network. If you were previously able to start the DHCP service, but it has since stopped, use Event Viewer to check the system log for any entries that may explain the cause.

Note To restart the DHCP service, click Start, click Run, type cmd, and then press ENTER. Type net start dhcpserver, and then press ENTER.
