HP to acquire LeftHand Networks

Sorry for the lack of publishings lately it has been a pretty hectic few months. I am just back from 2 weeks in the US where I was in Las Vegas at VMworld, in Cupertino at the HP Executive Briefing Centre and finally San Francisco where I presented at Oracle World. I am working on a bunch of postings right now so stay tuned for lots of new info, but I just this very minute saw this announcement that I thought I would publish immediately.

It has been announced that HP is to acquire LeftHand Networks for $360 million; helping to expand our virtualisation offerings. LeftHand specialises in iSCSI SANs and helps midsize companies and remote offices or branches of large corporations to protect critical business data.

LeftHand's portfolio of products will expand HP's reach in the virtualisation market with software that runs on both existing storage and industry-standard server hardware. LeftHand's software essentially allows a user to create a storage "cloud" connected via iSCSI as an alternative to Fibre Channel.

HP Virtual Connect wins Virtualisation Award

SearchServerVirtualization.com recently announced the winners of its first annual Products of the Year awards, spanning four categories: Virtualization Platforms, Hardware for Virtualization, Systems Management and Data Protection.

HP’s Virtual Connect architecture won Gold in the Hardware for Virtualization category!

This is not surprising as the customer adoption of Virtual Connect has been very high and it is now one of the most popular interconnects in our BladeSystem portfolio.

---EXTRACT---
HP Virtual Connect architectureServer virtualization simplifies server and operating system management in countless ways, but one area that has remained stubbornly resistant to improvement is managing a server's physical hardware -- specifically its network and storage connections. With its Virtual Connect technology, Hewlett-Packard Co. made serious inroads toward alleviating the problem of managing network and storage connections in a virtual architecture and has garnered our judges' vote for Gold.
In a nutshell, Virtual Connect is a novel approach to connecting and adapting server, local area network (LAN) and storage area network (SAN) domains with the aim of reducing cables and minimizing the number of switches IT administrators need to manage.
Available for HP BladeSystem servers, Virtual Connect consists of Ethernet and Fibre Channel virtualization modules that define server connection profiles for each server bay. This profile establishes and maintains Media Access Control (MAC) addresses for all Network Interface Controllers, the World Wide Names (WWNs) for all host bus adapters (HBAs), and SAN boot parameters. When a server is changed, its configuration and connection profile stay constant. When a new server takes its place, the same profile is assigned.
In this way, Virtual Connect decouples servers and the network so infrastructure changes don't require an administrator to make manual changes to LAN and SAN configurations, reducing the time it takes to reconfigure a server from hours or days to a matter of minutes.

BladeSystem Updates

First of all let me apologise for not having updated the blog in recent weeks; it has been a really busy end of year and I am only getting time to catch my breath this week before heading off to sunny Houston next week for a technology update on all things ProLiant. You can expect me to be out and about updating (berating) you our partners and customers as soon as I get back with all the latest and greatest info. Bookings are now being accepted :-).

So now to the updates...

Shorty is here
The biggest news in the past month has been the launch of the c3000 BladeSystem or 'Shorty' as we call it in HP. We had over 200 customers and partners at the launch events in Dublin and Belfast and interest since has been huge.

Shorty brings all the benefits and enterprise features of the bigger c7000 model to our SMB customers. It can hold up to 8 servers, storage or Tape Backup devices and is packaged in 6U. It plugs directly into standard wall outlets and is designed to work equally well in computer rooms or offices. It is a unique solution for the market and no other vendor has such an offering for the SMB market. More information on the product can be found at http://www.hp.com/ie/shorty.

You can also take an interactive guided tour of the c3000 at http://www.hp.com/go/smallsiteblades

There are a whole host of end of year BladeSystem and Insight Control Management toolset promotions to celebrate the launch of 'Shorty'. Your local HP reseller has all the information.

As well as the Shorty launch we also launched an 'All-in-One' Storage Blade, the AiO SB600c delivering 1.6TB of shared SAS storage. Check out http://www.hp.com/go/SB600c for more information.

The BL680c server also has arrived which is a quad socket, quad core Xeon server based on the new Tigerton chipset from Intel.

For those of you awaiting the new AMD Quad Core systems they have now slipped to March 2008 when HP will launch a full range of 2 and 4 socket blade and rack servers with the B3 chipset from AMD.

BladeBuilder University II (for HP Resellers)
On 13th November we will hold the BBU II. If you have sold at least one c-Class blade implementation or attended the well received Blade Builder University I in June, then this class is for you. This all new course focuses on business growth (versus selling technology in Blade Builder University I) and delivers modules that shows business partners exactly how to position the technology to our customers with real life examples and templates. More details to follow but places are limited and registration is now open on http://bladebuilderuniversity.com/

That's all for now - I'll post an update as soon as I get back from Texas!

Power and Cooling - HP Labs Technology

Power and Cooling has jumped right to the top of most customers IT agenda and HP has a lot to offer; from the power regulation technologies in our ProLiant and BladeSystem servers all the way up to the dynamic data centre portfolio of solutions. I have already published quite a lot of information in previous postings on this blog regarding power and cooling technology but I have come across 2 new items this week which I felt were worth sharing with you all.

First off we have just released the Insight Power Manager product which is an option for our ProLiant and Blade servers. This gives customers the ability to proactively manage the power utilisation of their servers, implement power policies inc. power capping and measure the actual power savings in € for your entire server estate.
>>Click here<< for further information. Other server vendors claim they also offer the functionality to control power but in reality they provide power control as part of the Windows 2003 OS which also needs modification to enable power control; furthermore there is no ability to measure real power savings or implement power policies. If you need more information please just let me know; this is a great HP .

Secondly 'Information Week' did a great piece on what HPs are doing with regard to power and cooling. If you would like to learn more about Dynamic Smart Cooling and see it working real time and hear about our strategy around cooling innovations in the datacenter, watch this video from Chandrakant Patel, HP Fellow, founder of HP Labs' thermal technology research program. You’ll need only 9 minutes to become experts !

How to size Power and Cooling for ProLiant and BladeSystem

Power and Cooling requirements are becoming ever more important on the criteria list when devising an IT solution. The ability to accurately predict in advance what power and cooling requirements your computer room or datacentre will require in order to support the proposed solution is of the utmost importance and can determine what the final solution will look like. HP has put a lot of effort into the whole power and cooling aspect of our servers by offering sizing tools, power management and monitoring tools and implementing innovative new technology in our BladeSystem and ProLiant ML/DL servers to both reduce your power requirements while not adversely affecting performance. Most vendors give you some basic sizing and monitoring tools but HP goes the extra step in providing strong integrated OS independent hardware based power management meaning our customers can leverage for Microsoft, Linux or VMware solutions.


For our channel partners this is a great way to add value to your customer proposals differentiating yourselves from the competition and providing the customer with information they will very much appreciate.

Latest Updates for BladeSystem and Management Tools

Apologies for the delay in updating the blog but it has been a busy month. I have been to the Worldwide BladeSystem Ambassador Academy in Houston, Texas and my head is busy trying to absorb all the new information I picked up there as well as deal with the backlog of work that I had waiting for me when I got back. So what's been happening this past month?

HP regains No.1 spot in Blades
Well I guess the biggest news from my point of view is that HP BladeSystem has finally recaptured No. 1 unit and revenue market share from IBM in the blade server market. It has taken us 10 Quarters but it has been on the cards ever since cClass was launched given the huge demand we have experienced and massive adoption of BladeSystem worldwide. Since cClass was launched HP has outpaced the market every quarter and according to IDC now holds 41.9% Revenue Share and 40% total Factory Units Share and has 10 times the growth of IBM in units and revenue year over year.

Anyway enough crowing what developments have there been in ProLiant and BladeSystem in the past few weeks.

New firmware available for Onboard Administrator
Version 1.3 of the OA is now available for download with some tweaks and fine tuning of the power utilisation and also implements zoned cooling in the cClass which further increases the cClass power and cooling efficiencies. One case of note was at a bank in the UK who upgraded the OA to version 1.3 and for their specific configuration with a full blade enclosure saw a 10% decrease in total enclosure power draw (300W). By implementing zoned cooling we now dynamically increase and decrease the RPMs of the fans in 4 zones. We increase the RPMs of the fans in that zone which require extra cooling whereas prior to 1.3 all fans would have increased.

SIM Updates
Systems Insight Manager 5.1 is now available and includes some nice new features (48 in fact but I will spare you and just point out the highlights) inc. Active Directory synchronization: integrates with group lists and authorization as an active directory resource group; Ease of use enhancements: quicker installation and easier configuration make HP SIM 5.1 easier to use than ever before; Improved enclosure views: enhanced view shows health status, environment information, and firmware revisions in life-like detail and a Custom tool wizard: allows you to easily integrate your programs, scripts and custom commands into HP SIM.

The best feature IMO which before was a stand alone product but is now a core feature of SIM is the Remote Support pack. The HP Services Essentials Remote Support Pack integrates with HP SIM to improve warranty and contracts management, provide optional automated support calls to HP, and add intelligent events and advanced troubleshooting resources. When the Remote Support Pack is fully installed, turning on remote monitoring for any particular device is then just one-click away within HP SIM. Enabling the Remote Support Pack will also give customers access to the new warranty and contract entitlement feature in HP SIM 5.1. For further information visit http://www.hp.com/go/hpsim

SAS Drive Technology - Large or Small?

I have had quite a lot of questions from channel partners and customers alike around hard disk drive technology. There is quite a bit of confusion in the market right now 1st of all around the new SAS (Serial Attached SCSI) hard drives and secondly since they are currently available in 2 form factors, Large Form Factor (LFF) and Small Form Factor (SFF); which drive type is best? Most hardware vendors have not made it any easier by making both types of drives available for their servers which means end users are faced with multiple options when trying to decide on a configuration.

First of all I should point out that SAS is the successor to SCSI. SAS is a serial technology where every drive can have it's own dedicated 'pipe' or bandwidth lane to the SAS RAID controller as opposed to traditional Parallel SCSI whose drives share a 'pipe' to a single channel on the SCSI RAID controller. For example the P400 controller in the HP ProLiant DL380 G5 is an 8 port SAS controller i.e. 1 port for every drive in the DL380 G5 which can house 8 Small Form Factor (SFF 2.5") drives.

HP have had a lot of success in the past with our Universal SCSI drive which meant that the same SCSI drive would go in our ML, DL or BL servers and MSA storage i.e. 1 drive for all servers and DAS (Direct Attached Storage) and shared storage solutions. As a result of this strategy which our customers have overwhelmingly applauded, HP has decided to adopt a new single universal drive type for the latest SAS and indeed SATA technologys based on the SFF 2.5" disk meaning our customers will only have to endure a single drive type transition. The industry is rapidly moving towards SFF 2.5" disks and LFF 3.5" disks are only a temporary stop gap to fill areas where capacity is more important than performance or even price/performance.

As stated HP has transitioned all of our enterprise servers to the new universal drive type; Small Form Factor 2.5” SAS (Serial Attached SCSI). We did this primarily to avoid our customers going through 2 transitions i.e. from U320 3.5” Parallel SCSI hard drives to Serial Attached SCSI (SAS) 3.5” Large Form Factor Drives and then to Small Form Factor 2.5” SAS drives.

HP currently offers SFF 2.5” SAS drives in 36GB and 72 GB capacities at 15K speeds. We also offer SFF 2.5” SAS 10K drives in 36GB, 72 GB and 146 GB. It is important to note that no vendor offers a 146GB 15K 2.5” SFF disk drive as this is still has not been launched by the hard disk vendors. This is not a major issue as the performance difference between SFF 2.5” 10K SAS and 15K LFF 3.5” SAS is very low. In a RAID 5 set of 4 drives this can be as low as 5% – see diagram below.





SFF Drive - Physical Advantages
The HP SFF 2.5” SAS drives are 2nd generation SAS hard drives compared to 3.5” LFF SAS drives which still use U320 parallel SCSI mechanics. The SFF drives use less power (about half that of LFF drives), are quieter, have a better MTBF (Mean Time Between Failure) rating increasing availability and reliability and the server supports more spindles which ultimately has the greatest impact on performance.


Sample Scenario
To achieve a 400GB RAID 5 disk partition we could use 4 x 146GB 2.5” SFF SAS 10K Hard Drives. This would give much better price/performance than the 3.5” LFF 15K disk solution, however the 15K 3.5” LFF drive array would be approximately 5% faster performing.


The HP list pricing (Feb. '07) for the 2 drive types are as follows
€355 for a 146GB 10K SFF 2.5” SAS Drive
€505 for a 146GB 15K LFF 3.5” SAS Drive

For a 400 GB RAID array based on 4 Hard Drives with both drives types in terms of price and relative performance. (See Diagram Below for performance data)

€1420 – SFF 2.5” 10K for 1200 IOPs approximately
€2020 – LFF 3.5” 15K for 1260 IOPs approximately

The price/performance for the 10K array would be far superior to the 15K solution while the performance is approximately 5% less.

The advantage of using SFF 2.5” 10K drives is that due to their smaller size you can have a total of 6 per DL360 G5 1U server, 8 per DL380 G5 class 2U server and 16 in both the DL580 G5 and ML370 G5. This means we can add up to 2 more drives a typical 2U server (8 as opposed to 6 with 3.5") to the RAID Array increasing not only the available disk space in the RAID array but also dramatically increasing performance. By adding a 5th 146 GB 2.5” 10K SFF SAS drive to the array we exceed the performance of 15K SAS (see diagram below) while still being a more cost effective solution.

At 5 drives IOPS approx.
15K LFF gives 1260 IOPS – limited to 4 drives in a 2U server.
10K SFF gives 1490 IOPS and costs less.
You are still left with the option to add a 6th drive to the RAID set at a later date if you would like to further increase the performance and/or size of the array.

At 6 drives IOPS approx.
15K LFF gives 1260 IOPS - limited to 4 drives in a 2U server
10K SFF gives 1650 IOPS and costs fractionally more.


Conclusions
In conclusion Small Form Factor 2.5” SAS drives are the new universal drive type in the industry. HP have adopted the standard universal drive for all of our servers meaning our customers will not have to transition again in 12-18 months time away from legacy 3.5” drive technology. Small Form Factor 2.5” drives are not available in capacities greater than 72GB in 15K disk speed.

SFF drives provide more advantages than a 15K 3.5”SAS drives in terms of power, cooling, reliability, and density and we have shown that the overall solution can beat 15K in terms of not only price/performance but also raw performance.
