Announcement : DS8870 V7.2

In case you've wondered why I didn't blog on the new DS8870 announcements last week, well there's a very practical reason : I was ill. But here we go now, with some delay. Actually there were two announcements last week. The first one introduces release 7.2 and some other new features : 'IBM DS8870 offers exceptional performance with new processors, microcode, drive options, and advanced functions to enhance data protection (ZG13-0298)'. The second one announces some withdrawals from marketing : 'Hardware withdrawal: Select features for IBM DS8870 (machine types 2421, 2422, 2423, and 2424) - Replacements available (ZG13-0266)'.

First, let's have a look at the new features. The DS8870 ships from now on with the Power7+ processor. As we all now, the DS8870 follows the evolution of the Power processor with some delay due to testing. Nevertheless this provides the DS8000 once again with a significant performance enhancement. With release 7.2 we also see the introduction of an all flash drive configuration.Combining these elements "helps the DS8870 to deliver up to 20% improvement in maximum IOPS in random I/O workload environments".

There are some enhancements to the Business Class systems. These systems target smaller customers who do not need the top notch performance of the Enterprise Class systems. The BC systems can now also go beyond a single frame and up to 16 core processors offering more flexibility for these customers.

There's also the introduction of 2 more disk models : the 1.2TB 10k rpm SAS drives and the 4TB 7.2k rpm nearline SAS drives. The new 1.2TB SAS drives differ from the former 1TB SATA drives in that they can be configured in a RAID-5 setup. No need for RAID-6 as is the case for the SATA and nearline SAS drives. This gives you a better raw capacity - usable capacity ratio.

At the same time the second announcement indicates that these disks are the replacements for the 900GB and the 3TB disks which will be withdrawn from marketing.

Availability (and withdrawal) date is December 6, 2013.
