Nathan Bedford Forrest, a Confederate general of despicable ideology and consummate tactics, spoke of “keepin up the skeer,” applying continued pressure to opponents to prevent them from regrouping and counterattacking. POWER7+, the most recent version of IBM’s POWER architecture, anticipated as a follow-up to the POWER7 for almost a year, was finally announced this week, and appears to be “keepin up the skeer” in terms of its competitive potential for IBM POWER-based systems. In short, it is a hot piece of technology that will keep existing IBM users happy and should help IBM maintain its impressive momentum in the Unix systems segment.
For the chip heads, the CPU is implemented in a 32 NM process, the same as Intel’s upcoming Poulson, and embodies some interesting evolutions in high-end chip design, including:
Use of DRAM instead of SRAM — IBM has pioneered the use of embedded DRAM (eDRAM) as embedded L3 cache instead of the more standard and faster SRAM. In exchange for the loss of speed, eDRAM requires fewer transistors and lower power, allowing IBM to pack a total of 80 MB (a lot) of shared L3 cache, far more than any other product has ever sported.
Since Oracle dropped their bombshell on HP and Itanium, I have fielded multiple emails and about a dozen inquiries from HP and Oracle customers wanting to discuss their options and plans. So far, there has been no general sense of panic, and the scenarios seem to be falling into several buckets:
The majority of Oracle DB/HP customers are not at the latest revision of Oracle, so they have a window within which to make any decisions, bounded on the high end by the time it will take them to make a required upgrade of their application plus DB stack past the current 11.2 supported Itanium release. For those customers still on Oracle release 9, this can be many years, while for those currently on 11.2, the next upgrade cycle will cause a dislocation. The most common application that has come up in inquiries is SAP, with Oracle’s own apps second.
Customers with other Oracle software, such as Hyperion, Peoplesoft, Oracle’s eBusiness Suite, etc., and other ISV software are often facing complicated constraints on their upgrades. In some cases decisions by the ISVs will drive the users toward upgrades they do not want to make. Several clients told me they will defer ISV upgrades to avoid being pushed into an unsupported version of the DB.
