IBM Upgrades DS8000 Series: All Models are now All-Flash

IBM DS8000 FamilyOn January 12 IBM announced some very serious upgrades to its DS8000 series of storage arrays.  Until this announcement only the top-of-the-line model, the IBM System Storage DS8888, was all-flash while the less expensive DS8886 and DS8884 sported a hybrid flash + HDD approach.  The new models of the DS8886 and DS8884 are now also all-flash.

But that’s not all: Every model in this product family has been upgraded.

The original DS8000 systems used a module called the High Performance Flash Enclosure (HPFE) for any flash they included, while these newer models are all based on HPFE Gen 2.  While the original HPFE was limited to a maximum capacity of 24TB in a 1U space, the larger 4U HPFE Gen 2 can be configured with as much as 153.6 TB, for more than six times the storage of the previous generation.  By making this change, and by optimizing the data path, the Gen 2 nearly doubles read IOPS to 500K and more than triples read bandwidth to 14GB/s.  Write IOPS in the Gen 2 have been increased 50% to 300K, while write bandwidth has been increased by nearly 4x to 10.5GB/s .

This kind of performance opens new Continue reading
