Primer on iSCSI and the permutations on BladeSystem

As iSCSI becomes more popular as an interconnect technology for storage and other devices, we had received a lot of questions as to how, why, what, works with iSCSI and the components of HP BladeSystem.

So, Dan Bowers and Ed McGee put together a primer to help answer a majority of the questions and configurations you may have or want to implement.

I have posted the primer to this community so download it and take a look. Let us know if it helps, hinders, confuses, or what additional things we can help with in this iSCI area.



A Blade Kill


In April, SPEC updated their server power benchmark to allow results for blade servers, and now HP has released its first blade result. 
 
HP just published a SPECpower_ssj2008 result for the HP BL280c G6 server blade.  It's the top score for a blade.   I talked to Kari Kelley, the BL280c product manager, and she called it a "solid kill."

The kill comment made more sense after Kari explained she played division-1 volleyball while at Texas A&M. "A kill is a good thing," she assured me.



SPEC didn't open up that benchmark to blades until their SPECpower_ssj2008 V1.10 came out this spring.  For a multi-node system (like a blade infrastructure), the benchmark has to be run with a full set of servers -- so a c7000 enclosure filled with 16 BL280c servers in HP's case. Power is measured at the AC line voltage source, while the test itself monitors throughput and power usage at various performance levels, including periods when the servers are 100% idle.  HP has written this whitepaper that talks more about the benchmark methodology.

For the BL280c G6 server, the overall result was 1877 ssj_ops/watt.   Full details here.  For full details about kills, along with sets and spikes, you'll have to talk to Kari.

SPEC and the benchmark name SPECpower_ssj are trademarks of the Standard Performance Evaluation Corporation. The latest SPECpower_ssj2008 benchmark results are available on the SPEC website at http://www.spec.org/power_ssj2008.

A lesson in economics – Price Transparency

It doesn’t happen often, but here is one of those situations in life where that dismal science, economics, can be useful and fun.


First a little definition ….


Price transparency is defined as a situation in which both buyer and seller know what products, services or capital assets are available and at what price.


Now, price transparency is a way of life in the business of standards-based, x86 servers. This even includes blade servers.


Go to any of the major vendors’ web sites such as Dell.com, IBM.com, HP.com or even resellers such as CDW.com and you can freely look up at least what each vendor’s list price is. You can bet that we vendors do this all the time to ensure we are ‘competitive’ with each other. And so do all of our customers. In fact, our customers know our list price and our competitors’ before any of us set foot in a customer’s place. That helps keep us vendors on our toes to deliver better products while keeping prices lower for customers. The x86 market is a living example of price transparency.


Until you get to the newest member of the x86 server community …


Cisco claims on their web site that their recently announced Unified Computing System is “Reducing total cost of ownership at the platform, site, and organizational levels”.  The glaring omission is “minus the cost”. One would presume this includes a competitively priced set of compute, storage, enclosure, interconnect, management tool, software licenses and support components. But aside from Cisco’s word for it, this cannot be verified.


This is because Cisco, unlike the other server vendors, does not publish their UCS list price on their web site. Nor do their resellers seem to.  This makes it difficult for customers (or competitors) to independently validate features to prices in a standards-based industry.


Given Cisco’s traditionally high margins on network plumbing gear (65% vs. the 20% margins of x86 servers), vendors, analysts and customers could be forgiven if they were suspicious of high prices for UCS. In fact one could see some of Cisco’s UCS prices needing to be three times as high as industry averages to meet their business model.


So come on, how about a call for the free market and industry standards.  Are we all about the same price? Is Cisco really cheaper?

Managing HP servers through firewalls with Insight Software


I came across an interesting white paper that identifies possible ways of managing HP servers with HP Systems Insight Manager and Insight Software deployed in the area of the network that is considered more secure than the standard production network. This is not a best practices document. This document provides information that can enable system administrators to create management solutions appropriate for specific computing environments.


Here is the link: ftp://ftp.hp.com/pub/c-products/servers/management/hpsim/hpsim-53-managing-firewalls.pdf


Installing and configuring HP-related components in Essential Business Server on an HP BladeSystem c3000 chassis

To fully use the features in the c3000 hardware, you must be able to add and configure software in EBS. This updated customer-viewable document covers installation of SNMP, Support Pack, Management Packs and how to add HP updates into Microsoft® System Center Essentials. See the white paper below.

Pity the "Server Guy"

My brother-in-law David manages a mid-sized construction business, and owns seven or eight servers to handle the data.   But don't bother asking him how much data they hold, or what  processors they use. In fact, it's pointless to ask anyone in his office; they'll all give the same answer:  "I don't know. Ask the Server Guy."
 
Who exactly is the Server Guy?  To an SMB company like David's, Server Guy is the mysterious geek who crawls into a back-office closet clutching two cables and a USB thumbdrive, and emerges fifteen minutes later to declare that email is working again. Server Guy brings IT to the small- and mid-size businesses who either have a 1-man IT department, or depend on part-time or contractor help.


Tam Harbert notes that more and more of these Server Guys are approaching Ingram Micro and asking whether blade servers might be right for the 20-to-100 employee, server-closet crowd.  And, Tam says, increasingly the answer is "Yes."


Why?  Partly, Tam notes, it's the potential for saving money from their smaller footprint  and higher power efficiency. But Arlin Sorensen, president of Heartland Technology Solutions and a Server Guy himself, nails an even bigger reason:


"A lot of our customers aren't equipped to handle the number of servers that they end up having...When you're dealing with 15 different stand-alone servers that were bought at 15 different times, then you have to deal with 15 different experiences in how those things are going to act. The beauty of blades is that the servers all respond and react the same way."


Blades make Server Guy's job EASIER. When you have a jumble of servers, switches, and storage wired together with a rats-nest of connections, the only cross-platform, intuitive management tool that you have is the main circuit breaker on/off switch.    Blades change all that -- they give Server Guy a way to maintain servers in a quick, consistent, predicable manner.


Consider all the things Server Guy might be called upon to know.  (Martin at BladeWatch did just that recently -- and to me his list is both accurate and daunting.)  


But with tools like BladeSystem Onboard Administrator, Server Guy now has graphical, point-and-click tools that let him manage the IT hardware without two hundred hours of classroom training and three expensive industry certifications.  Intuitive tools mean Server Guy is more productive.


How?  Well, let's say my brother-in-law calls Server Guy and says "it sure seems hot in the server closest."  Since most servers have temperature sensors in them, Server Guy could download a bundle of User's Guides, drive down to the office, figure out what settings he needs on a serial cable, plug it into each system, and -- if he remembers all the login passwords -- fetch the temperature readings on each piece of equipment.  He could compare those to the tech specs on the hardware maker's web sites, then finally report to my brother-in-law that everything's OK.


Or...he could simply pull up a browser and remotely look at the Bladesystem Onboard Administrator status screen:


 


No manual needed.  The green bar  obviously means things are OK. There are little graphical orange and red hash marks -- nicely labeled with temperatures, and "Caution" and "Critical" indicators -- showing how much hotter it would need to be before there's a problem. 


The BladeSystem team spends lots of their time developing tools like this, so Server Guy only has to spend a tiny amount of time using them.


Server Guy, if you're out there, let me -- or some of our colleagues -- know what other help you need.   Also, call my brother-in-law.  He says the Internet is broken again, and the "any" key is missing from his keyboard.
