Are you keeping score?

However, unlike Oracle and Intel, who in their own ways are both becoming very rigid and proprietary. IBM is going in the opposite direction by actually opening up their own technology as well as embracing the open source community.

Are you keeping up with all of the changes taking place with IBM’s Power portfolio over the last 2 years?  How could you as there have been so many changes to just about every area on the platform.  Just in case, let’s review some of the features and changes.  Now, since I don’t work at IBM, don’t have a magic 8 ball or a direct line to Doug Balog, IBM’s Power General Manager there is a chance I will get something wrong and I’m sure I’ll leave a few things out.  What I will do though, is not talk about any upcoming products – which between you and me – They will be freakin awesome!

  • Power8 processors support both Big Endian and Little Endian
  • Little Endian offerings are with Linux: RedHat 7.1, SUSE 12 & Ubuntu 14 & 15

  • 40 Gb RoCE adapters
  • PowerVC based on OpenStack replaces Systems Director (portions of it)
  • PowerVC integrates with VMware’s vRealize allowing it to manage & provision Power Systems
  • Gen 2 of a Converged solution called PurePower using S822(L) servers + V7000 + Mellanox switches
  • 2X performance increase over Power7. Greatest increase that I recall from 1 gen to the next
  • 3X greater memory bandwidth for Scale-Out over Power7/7+ Entry servers
  • Just under 2X greater memory bandwidth for Power8 Enterprise vs Power7/7+ Enterprise servers
  • 3X greater I/O bandwidth for all Power8 servers over all Power7/7+ servers
  • 2X more L2 cache
  • Addition of L4 cache
  • SMT8 that is dynamic per VM unlike Intel with their static 2 way Hyperthreading
  • Up to 1 TB Ram per socket
  • Centaur buffer supports DDR3 & DDR4 memory
  • Scale-Out servers (S & L models) use Enterprise Memory just like the Enterprise servers
  • Significantly more Fault Isolation Registers & Checkers
  • Significant reliability enhancements to processor, cache, memory & I/O subsystems
  • Gen3 I/O Drawers with more PCIe slots per drawer
  • Gen3 PCIe slots (x8 & x16) in all servers
  • Available split backplane in ALL Scale-out servers – YEAH!
  • Significant increase in the number of internal Scale-Out server disk slots: 8 – 18 slots
  • 6 or 8 x 1.8″ disk slots (model dependent) using IBM’s Award Winning (Is it?) Easy Tier
  • Hot swap PCIe slots in ALL models
  • Scale-Out internal disk RAID cache increased from 175 MB in Power7 to 7 GB
  • PowerVM, PowerKVM and RHEV hypervisor options
  • Bare-Metal server option (certain models)
  • Enhanced Voltage Regulator Modules (VRM)
  • Enhanced EnergyScale
  • Some models lowered their software tier from Large to Medium and Medium to Small
  • Some servers received improved warranties
  • Power Enterprise Pools with Mobile Cores & Mobile Memory
  • Integrated Facility for Linux (IFL’s) on E850, E870 & E880
  • L model servers that use PowerVM is called PowerVM Linux Edition equivalent to Enterprise Edition
  • Supported with SAP HANA
  • All non-L models supported with EPIC
  • All Enterprise servers supported with EPIC
  • Delivering roughly 2X performance increase over Intel Haswell EP/EX processors
  • Power8 has 3X greater memory bandwidth than Intel Haswell EP memory in Lock-Step mode
  • Power8 has 2.5(ish) greater memory bandwidth than Intel Haswell EX memory in Lock-Step mode
  • Power8 has 2X greater L1 cache
  • Power8 has 2X greater L2 cache
  • Power8 has 2.5X greater L3 cache
  • Intel has no L4 cache
  • Intel has significantly fewer Checkers
  • Intel does not use anything similar to Fault Isolation Registers
  • Intel 1 & 2 socket servers do not support Machine Check Architecture (MCA)
  • Only Intel 4 socket & greater servers support Machine Check Architecture (MCA)
  • Intel rates their memory capabilities in performance mode which has limited RAS capability
  • For Intel to increase memory resiliency, must use lock-step mode which decreases performance
  • For Intel to increase memory resiliency, can use memory mirroring reducing memory capacity by 1/2
  • All Power8 servers have at least 1 Coherent Accelerator Processor Interface (CAPI)
  • Several CAPI solutions are available today with more coming (very soon – that’s the only hint)
  • Using IBM’s Advanced ToolChain delivers an enhanced SDK & GCC delivering increased results
  • IBM optimized software stack for Power8 delivering greater results per core
  • Optimized ISV stack for Power8 delivering greater results per core
  • ISV’s like MariaDB, WebFocus Express, Redis Labs, ColdFusion, EnterpriseDB, Magento
  • ISV’s like McObject, Veristorm, HelpSystems, SugarCRM, Zato, OpenPro and many more
  • Guaranteed utilization levels from 65 – 80% depending on the model
  • Backbone of Watson
  • Supports Apache Hadoop & Apache Spark
  • Supports BigInsights
  • Supports internal disks for Big Data
  • Supports superior BD storage option using Elastic Storage Server: S822L & GPFS Native Raid
  • Run DB2 10.5 with BLU Acceleration 2X faster than Intel
  • WebSphere & Cognos faster
  • SPSS faster and many more
  • 150+ members in OpenPower Foundation
  • Blue badged Power based solutions
  • Non-blue-badged Power based solutions available
  • PowerVP is awesome
  • Virtual HMC is coming (was a IBM SOD)

I tried to create an exhaustive list to make the point that IBM is investing, engineering and building game changing technology to help customers solve real solutions. However, unlike Oracle and Intel, who in their own ways  are both becoming very rigid and proprietary.  IBM is going in the opposite direction by actually opening up their own technology as well as embracing the open source community.  The list of ISV’s, the use of OpenStack, the use of a open source hypervisor and the most recent announcement whereby VMware’s vRealize will be able to provision & manage Power Systems is a testimony to the change taking place within IBM and with customers.  Expect more of the above and more beyond this. Expect it to blow your mind.

I may come back over time and enhance this list if I get froggy.  Of course, if you are a customer you could always invite me to speak with you and I would be happy to discuss any and all of this.

What would you like to see in addition to the extensive list above?
