HP Solid State Drive technology
Overview
HP solid state drives (SSDs) have no moving parts, which makes them able to operate in more extreme environments than
traditional hard disk drives. Available in 32-GB or 64-GB versions from HP, these first generation drives are designed
specifically for ProLiant c-Class server blades.

Operating environment for HP SSDs
HP server disk drives are available in three levels based on performance: Entry, Midline, and Enterprise. The HP solid state
drives introduced in September 2008 represent a level of performance, reliability, and capacity roughly equivalent to Midline
server disk drives. More importantly, however, HP server SSDs can deliver this level of reliability in operating environments that
are unsuitable for traditional disk drives (Table 1-1).

HP SSD Futures
The HP server SSDs introduced in late 2008 represent the first generation of SSDs for ProLiant servers. In the first half of 2009,
HP expects to introduce hot-plug SSDs using standard drive carriers. These drives will be supported across the ProLiant product
line.
As is already the case with hard disk drives, HP is working to develop separate classes of SSDs, each designed to meet the
specific capacity, performance and reliability requirements for particular applications. Table 2-1 summarizes the current goals
for creating Entry, Midline, and Enterprise SSDs in the future as the technology continues to evolve.

Meet the Expert— Brian Purcell
Mark Brian Purcell is an HP hardware architect whose job is critically important to
the success of AMD-based ProLiant servers. He is responsible for reviewing the
future chipset and processor offerings, and he works closely with vendors to
evaluate how their products can best be integrated into all HP server products. He
also provides feedback to vendors on what features are needed to ensure that HP
products meet or exceed customer requirements and expectations. Scot Wurster,
Brian’s manager, adds “Brian is very willing to help anyone facing a problem.
When presented [with] a challenge from marketing, the gears [start] turning in his
head. He will come up with a solution to fit the customer’s need—usually a couple
of different ways to fulfill that need He has a positive ‘can do’ attitude, and he
works very well with other people. He also works closely with AMD, providing
product feedback to improve their products’ reliability and performance..”
Brian successfully balances his work and personal life through hobbies such as
golf, motorcycles, radio-controlled sailplanes, and coaching his son’s (Colin)
baseball team. But his most interesting hobby is playing trombone in the HP
Houston Jazz Band. Brian has played in the Jazz Band since 1996. Brian’s wife
of 12 years, Sharon, plays saxophone and directs the band. They also play in
their church orchestra. But there’s more—Brian has two brothers (Mike and Bill)
who also work for HP. Below are excerpts from an interview with Brian.
Why did you decide to become an engineer?
Brian: While growing up, my curiosity led me to disassemble electrical devices
such as Walkmans, radios, etc. My father always told me, “If you break it, you’d
better know how to fix it!” When I was eleven, we got our first computer. I quickly
learned how to use it, and I developed my programming skills. At fourteen, I
developed an algorithm to generate magic squares (in multiples of four). As computer programming became second nature to
me, I decided that a blended degree in Electrical Engineering and Computer Science would be perfect!
What is your most interesting research?
Brian: Modifying and applying my father’s principle into our system architectures. “If [it breaks], you’d better know [what went
wrong and] how to fix it.”
I am a huge proponent of embedding logic analyzer functionality within our CPLDs (complex programmable logic devices) to
help engineering and service teams quickly determine the source of system behaviors and faults. As a normal part of our system
validation and margin testing, we occasionally encounter power and/or thermal faults. It is often difficult or time-consuming to
repeat the failure; thus, it is very important that we catch and log the failure on the first occurrence.
This is especially important when our servers have multiple PCAs,where each PCA has multiple, independent voltage regulators.
We have to be able to indicate the exact failing PCA or replaceable voltage regulator module. When we can identify the exact
component that failed, it improves customer satisfaction.
The embedded logic analyzer functionality has matured significantly over the past few product generations, and it continues to
be successfully employed by multiple platforms across both the ISS and Business Critical Solutions (BCS) server teams. The
current architecture improves the fault detection capabilities and provides a very detailed system status “snapshot” at the time of
failure.

How much customer input goes into the design of your products?
Brian: Customer feedback is very important to us because customers are more likely to purchase HP products if we can meet
their requirements. I personally go through several design concepts before I finally settle on the top one or two design
recommendations. Some of the questions I always ask are
•Is the solution mechanically friendly to the customer and service person?
•How can we improve the total customer value for the product, extend the server’s lifetime, and lower the total cost of
ownership?
•How can we “future proof” our product design and provide customers with an upgrade path as technology evolves across the
lifetime of the platform.
As the server development model has evolved industry-wide, what adjustments has ISS engineering made to
maintain technological leadership?
Brian: There has been a significant paradigm shift in the relationship between product development and how our engineers
develop their technical and debugging skills. Prior to the prevalence of ODM (outsourced development model) or JDM (joint
development model) product development, our engineering staff gained knowledge through continuous, hands-on experience.
During the course of the product development cycle, engineers would naturally progress from fixing simple issues, to debugging
basic problems, to understanding various hardware and software interactions, and then to debugging significantly complex
issues. Today, the ODM/JDM partner is quite capable of fixing the less complex issues. This leaves HP engineers to debug a
higher percentage of complex issues than before, which demands that they understand how all of the software and hardware
pieces interact with each other.
The ODM/JDM model gives senior engineers more opportunities for one-on-one mentoring of younger engineers to strengthen
their system architecture knowledge and debug skills. This gives younger engineers a deeper understanding of system
architecture, and it helps them to continue developing innovative technologies for HP products.
Common SM CLP scripting commands for ProLiant server management
This is the last in a series of three articles that discuss common SM CLP (Server Management Command Line Protocol) scripting
commands. Links to the previous articles are listed in “Additional resources” at the end of this article. SM CLP is one of the
communication, or access, protocols that can be used with the Systems Management Architecture for Server Hardware
(SMASH). This article discusses the SM CLP syntax and properties.
SM CLP is accessed using Secure Shell (SSH). SSH can be interactive (as in a shell) or it can execute in a "command" mode by
processing a single command at a time suitable for scripting. The following examples use SSH command mode, using a
Windows utility (plink) that provides SSH command line support. Plink and PuTTY executables, source code, and license terms
are freely distributed on the web. Other SSH command line utilities should support this functionality in a similar manner.
The SM CLP organizes commands into different functions— targets, properties, and verbs.
•Targets refer to the grouping of related objects, such as the host server (system1) or iLO, the "management access
point" (map1). Targets can be subdivided into smaller groups using a folder-style naming convention—all the
subordinate targets are presented in the output from the “show” verb.
•Properties represent related attributes for the given target.
•Verbs represent the actions that can be taken on a given target and property.
The following examples specify user credentials on the command line. If user credentials are not specified, iLO 2 prompts for
account credentials, interrupting the process. iLO 2 also supports SSH key-based authentication.

Retrieve properties of the host system
The following example illustrates how to retrieve the properties of the host system using the show system1 command.
Administrators can access specifics within system1 by appending subordinate targets, such as system1/firmware1, to reference
the host ROM version.
C:\Program Files\putty>plink -ssh -l admin -pw password ilo2system.corp.net show system1
show system1

Retrieve iLO properties
The following example shows how to retrieve the iLO properties (map1 properties in CLP terminology) using the show map1
command.

QuickTip ⎯Using Fabric Manager software to configure switches
This QuikTip addresses licensing requirements, installation, and downloads for Fabric Manager (FM) software. This information
applies to Cisco MDS 95xx Fibre Channel Switches.
FM software license not always necessary
Here are the facts about FM license requirements:
•A license is not required to install Fabric Manager Basic for the MDS.
•A license is only applicable for Fabric Manager Enterprise.
•Fabric Manager is free software as long as only one fabric is managed at a time. Because a fabric can have multiple
switches, all of them may be managed without the FM Server Package license.
FM software installation
FM software can be installed using the CD that comes with the switch, or it can be downloaded from the HP Web site.
Here is the link to the latest downloadable Fabric Manager software (MDS Management CD) for Cisco switches:

peId=12169&prodSeriesId=1849157&swLang=13&taskId=135&swEnvOID=54
Note
When the install CD is used, it also installs postgresql as the DB for the FM server.
