HPC servers follow Intel & AMD x86 processor roadmaps .HPC servers will be thin nodes with 2P or fat nodes with a large memory for SMP jobs and 4P. For HP AMD servers, we currently have Magny-cours, and Lisbon on one SL (SL335)The current HP Intel servers are based on Westmere-EP for 2P. There is also a 2P server based on Nehalem-EX , the BL620G7, which offers up to 512GB of memory (2x16x16GB mem)The future major processor updates are Intel Sandy bridge and AMD InterLagos.IL is planned for Nov 2011.SB is planned for Feb 2012.
these functions will e common across ALL ProLiant Gen8 platforms.There are FOUR key new functional areas (in addition to remote console/remote power/virtual media) that our new iLO Management Engine covers:PROVISIONING:Our new Intelligent Provisioning takes all of our strengths of products like SmartStart, PSPs and HP SUM, enhances them with the latest ease of use features and places them where you can use them immediately: on the system boardMONITORING:A long-time desire of many of our customers is now offered as an industry-first by HP: agentless management. Base hardware health monitoring and alerting functions now run straight on the iLO hardware, independent of the operating system and the x86 processor. DIAGNOSTICS:While HP server failures are few and far between, some failures can be extremely hard to reproduce, may escape regular diagnostic runs and therefore may sometimes take too long to fix. With our new Active Health System we offer an always running diagnostics system, recording every configuration change and every alert, so as to facilitate faster root-cause analysis and problem resolution.SUPPORT:With iLO Management Engine we also offer a revolutionary built-in remote support system that provides phone-home capabilities which can either interface directly with the HP backend (which is ideal for smaller customers, or for remote sites without a permanent connection to the main site), or can use an HP Insight Remote Support host server as an aggregator.
Instead of embedding the adapter on the server system board like we do on the current servers and our customers have to accept the default adapter on the server, FlexLOM provides choice. Just like a box of chocolates, you can choose your flavor. The ability to upgrade when needed thus offering the model of buy as you need plan e.g. start with 1Gb and replace with 10Gb at a later stage.Because of that flexibility, you may not need to add an Ethernet Mezzanine card thus saving you $. An additional mezzanine card may cost an additional $300 to $800 ILP.
With over 5 million SAS Smart Array Controllers shipped, HP Smart Array controllers have delivered several innovations for protecting customer data including the first RAID, First RAID 6/60, First Cache and first Flashback write cache.HP Gen8 Smart Arrays bring significant enhancement, starting with a 2X increase in performance (final results awaited)The Gen8 servers support up to 2 GB Cache provide faster access to data, and improves rebuild times.With twice the number of drives supported as previous generations, you can attach up to 227 drives combined internal and external to the ProLiant Gen8 server compared to 108 drives on ProLiant G7. With the explosive data growth that most customers are seeing in their environments, this feature will help tremendously.Flash back write cache is now standard on most Smart Arrays Controllers. FBWC uses a capacitor and flash memory to hold ‘write cached’ data instead of a battery and the DIMM. The main advantage of this is, when the power goes out, the write cache is moved to Flash and held pretty much indefinitely. No worries though, when the server is powered back on, and the data in flash is written to the drive, the data is erased from the flash module.Improvements in Parity initialization , up to 95% means that customers can setup and be productive quickly ACU management tools are now embedded. Much easier to access . Migrating data from one generation to next seamless lets customers be up and running more quickly with newer servers. Firmware and driver updates for drives and controllers are on the same cadence.SSD Wear Gauge allows customers to track the number of write and erase. How tired is your SSD and is in under warranty? Security- Secure erase utility completely erases your data before removing drives.Manage drives across the entire datacenter with scripting. Faster time to resolution on drive issues.Space Constraints/Real estate economics (Density)- Larger capacity drives and greater density of drives on servers. Managing the growing storage needs of customers by adding large capacity drives and support for 2x the number of drives on previous generations.Investment protection: As technologies evolve and change is the IT future proof with a forklift upgrade, Headroom for growth- 6G Smart Array controllers are backwards compatible with the 3G SAS drives and disk enclosures.
HP SmartMemory is unique technology being introduced for ProLiant Gen8 servers that unlocks certain features only available on HP Qualified memory. A unique signature written to the memory SPD (serial presence detect) verifies to our new servers that HP SmartMemory, that has passed HP’s rigorous qualification and test process, is installed.It is ideal for customers who want assurance of buying genuine HP qualified memory, performance tuned for HP ProLiant and BladeSystem servers and enhanced support through HP Active Health.As a result of our engineering work and the ability to assure customers that have genuine HP SmartMemory, several unique specifications will be available on HP ProLiant Gen8 servers. First, HP will be able to operate low voltage (1.35V) HP SmartMemory at the same 3 DIMMs per channel (3DPC) at 1333 MHz that 3rd party memory will have to run at 1.5V to achieve.Second, HP will be able to operate UDIMM memory at a 25% faster bus rate that third party memory at the same voltage.Substantiation:15 - 20% less power than 3rd party memory at 3DPC – HP Internal Lab testing/calculations 25% greater throughput at either 1DPC or 2DPC versus 3rd party - HP Internal Lab testing/calculations
Beginning March 6th we’ll begin to deliver our new line of ProLiant Gen8 servers, including three product lines that are of particular use in HPC.The ProLiant DL family of racked servers provides maximum configuration flexibility, with balanced efficiency, performance and management. From 1u “pizza box” servers that have powered many major HPC clusters, to memory or storage rich servers that service specific HPC workloads.HP BladeSystem, the ProLiant BL family, has been the most successful system in HPC since shortly after the launch of c-Class in 2006, with more HP BladeSystem clusters on the TOP500 list of the largest supercomputers in the world (www.top500.org) than any other system architecture. The reason? HP BladeSystem is the essence of HPC convergence, with everything you need for an efficient HPC cluster within the enclosure – servers, storage, networking, management, etc. But as our HPC solutions grew into hyperscale, we found the demands of our largest sites required a new way of thinking about servers for HPC. From that clean sheet design came the HP ProLiant SL family, designed specifically for the most challenging HPC environments, driving new levels of performance, scalability, efficiency and agility.

Accelerators are used to increase the performance of HPC systems by accelerating computational or storage hot spots in HPC applications, enabling SL200s systems to achieve new levels of performance/$/watt/ft2SL200s systems support integrated NVIDIA Tesla GPUs, including the latest M2090 GPUs that deliver up to 30% more performance than previous generations, and the M2070Q GPU that combines computational performance with remote graphics support. This allows the SL250s to act as graphical server, enabling workstation applications to be moved into the datacenter, where they are closer to the data needing to be visualized.SL200s systems support the PCIe IO Accelerator, a solid state storage device that provides a high speed cache for storage operations, increasing I/O performance for data centric HPC applications.The SL200s will also support the Intel Many Integrated Core (MIC) processor in the future. MIC will combine many x86 cores into a single piece of silicon, enabling highly parallel HPC applications to be accelerated, or run entirely, on MIC to significantly increase their computational performance. And being an x86 core, it will run the standard IA instruction set, simplifying porting of applications to take advantage of MIC.

ConnectX-3 : FDR adapter chipWhen running the InfiniBand protocol, it supports Remote Direct Memory Access (RDMA); Fibre Channel over InfiniBand (FCoIB); and Ethernet over InfiniBand (EoIB). RDMA is the key feature that lowers latencies on server-to-server links because it allows a server to bypass the entire network stack and reach right into the main memory of an adjacent server over InfiniBand links and grab some data.The ConnectX-3 chip is small enough to be implemented as a single chip LAN-on-motherboard (LOM) module. The ConnectX-3 chip will also be used in PCI adapter cards and in mezzanine cards that slide into special slots on blade servers.HP FDR InfiniBand blade switch module - Monadnock consists of two new InfiniBand switches for the C-class blade system. They will be FDR InfiniBand (56Gb/sec) capable devices.HP IB FDR/EN 10/40Gb 2P 544M Adpr - The Wachusett parts implement the next generation of Mellanox chip technology called ConnectX-3. They offer higher performance and lower power and latency than the previous products.
