An Early Valentine’s Day present from Power Systems

IBM is providing Power Systems clients with an early Valentines Day present – a POWER7+ processor refresh for (most of) the Power Systems product line.  The POWER7+ processors made their debut in October 2012 in the “D” models of the Power 770 and Power 780 systems.

This announcement brings the POWER7+ processor advantages of higher clock speeds and built-in cryptographic and memory compression accelerators to the Express (low end) Power Systems products. The announcements today include POWER7+ versions of the Power 710, Power 720, Power 730 and Power 740 Express servers, a completely revamped Power 750 Express server. There is also a new entry to the Power Systems mid-range product line,  the IBM Power 760 server, that supports up to 48 cores.

The new POWER7+ processor based systems offer twice as much memory as their POWER7 predecessors – up to 2 Tb of memory in the new Power 760 model. Most of the Power clients I talk to tend to run out of memory before they run out of processor capacity, so the increase will certainly be appreciated. By the way, the new, higher capacity memory modules will not work in the older “C” model systems, so if you need the additional memory you will need to step up to the new systems.

All these new systems include new POWER7+ reliability features such as a self-healing capability for L3 cache and the ability to restart a processor without restarting the system. These features help avoid unplanned outages and improve the ability to provide concurrent firmware updates to avoid some planned outages.

When coupled with PowerVM enhancements that allows virtual machines to be sized as small as 1/20th of a core, the POWER7+ “D” model systems will support up to twice as many virtual machines (aka LPAR) as their POWER7 based predecessors.

The new systems will be supported by AIX, IBM i, and Linux, except for the Linux-only 7R1, 7R2 and p24L systems. There is a statement of direction for AIX 5.3 support coming in the future for clients that have purchased the AIX 5.3 Service Extension

If the additional performance and doubled memory wasn’t enough, IBM has priced the 710 and 730 Express servers right on top of their X86 competition–making Power Systems even more attractive to clients that focus on cost of acquisition.

Power7+_Summary

Now things really get interesting with a POWER7+ version of the extremely popular Power 750 Express server. The new “D” model isn’t just a refresh of the old model with POWER7+ chips – it is really a blend of the Express 750 and mid-range Power 770 technologies.

You’ll notice that the new Power 750 Express is in a bigger, 5U form factor. When you see all the new capabilities you’ll know why they needed a bigger box. Like the predecessor 750, the “D” model has 4 sockets with 8 processors per socket for 32 total cores running at 3.5 or 4.0Ghz. The new 750 can be equipped with up to 1Tb of memory and will support up to 640 virtual machines running AIX, IBM i or Linux.

As the TV commercials say: “But wait there’s more”. The Power 750 Express server sports the same kind of I/O you would expect in a Power 770. For starters, it has 6 PCIe Gen 2 slots and 6 disk bays. It also supports four different multifunction I/O cards, that can provide, for example, two 10Gb Converged Network Adapters and two 1/10Gb Ethernet ports.  The Power 750 also includes two GX++ ports, each with 20Gb bandwidth.  Finally, the Power 750 includes a split backplane allowing you to divide up the internal drives between two virtual machines; for example, dual VIOS servers. The Power 750 also comes with three year of maintenance in the purchase price.

With all of these changes, the 32 core Power 750 Express Server will rival the performance of the top of the line 64 core POWER5+ 595 system of a few years ago —at a fraction of the price.

IBM also is announcing a new model to the Power Systems family, the Power 760. The Power 760 is a mid-range server, a baby brother to the Power 770 server. The Power 760 is intended as a server consolidation platform with up to 48 cores of capacity. The processors are supported by up to 2 Tb of memory to allow for up to 960 virtual machines in a single 5U system.

The Power 760 shares the same 5U form factor as the Power 750 as well as the Power 770 inspired I/O configuration including the multifunction I/O cards, dual GX++ busses and the split backplane. It also includes the same reliability features as the Power 750 Express and three years maintenance of hardware maintenance in the purchase price.

The Power 760 also offers Capacity Upgrade on Demand (CUoD) for processors to provide for even more flexibility.  The CUoD feature allows clients to activate processors to respond to increased workloads without interruption. The CUoD capability is limited to permanent activation only and does not include CUoD for memory.

There are a number of other new products announced today including: POWER7+ updates to the Linux-only PowerLinux 7R1 and 7R2 systems, new I/O including a 16Gb fibre channel adapter. There is also a IBM i 7.1 Technology Refresh 6 (TR6) with lots of enhancements for IBM i and PowerHA SystemMirror for IBM i.  Finally, there is also a new Power Systems version of the PureApplications System for increased performance and workload density.

There’s no new AIX Technology Levels announced today in keeping with the AIX Release Strategy, but there are updates to AIX Solution Edition offerings for Cognos and SPSS.

There is much more detail in the announcement letters that are available on ibm.com/power. A Smarter Computing webcast highlighting the announcements is scheduled for 11 AM EST on Feb 5.

About Jay Kruemcke

Jay has had more than twenty years of experience in the information technology industry. Starting from a rather humble beginning at IBM, Jay became a mainframe systems support programmer. Eventually Jay joined the AIX operating systems development team early in that product's development. Jay leveraged technical skills that he built in systems management to establish himself as a member of the IBM Austin Executive Briefing Center. His expertise in systems management with the SAP ERP system enabled his first product management role, as the owner of the Tivoli management product for SAP. Over the next three years he established that product as a success with the help of a strong development team. Jay returned to AIX in a product management position initially focusing on managing new requirements for the AIX operating system. Jay established himself as a subject manager expert in AIX and Power Systems virtualization and became a frequent guest at conferences around the world. Jay succumbed to the dark side and spent four years in IBM marketing in which he introduced AIX version 6 and AIX version 7 and many product innovations including the first every open beta program for an AIX release and a significant restructuring of the AIX offering structure and prices. Jay was part of the cloud software development organization and and focused on managing development engagements for clients deploying clouds using Power Systems servers with PowerVC and related products. In March of 2016, Jay retired from IBM and started in a new role as a product manager for SUSE, the Open Software company. Jay new focus is on enterprise Linux for POWER and ARM processor based systems.

    Can’t wait for the lovely discussions we have with customers when we tell them their workload only needs .05 of a CPU. They can’t seem to believe such a small amount can run their application.
