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

IBM Refreshes Broad Swath of Flash Offerings

IBM Storwize All FlashYesterday IBM unveiled a sweeping update of its existing flash storage products.  These updates cover a range of products, including IBM Storwize All Flash arrays: V7000F, V7000 Gen2+, and V5030F, the FlashSystem V9000, the IBM SAN Volume Controller (SVC), and IBM’s Spectrum Virtualize Software.

The company referred to this effort as a part of a: “Drumbeat of flash storage announcements.”  IBM has a stated goal of providing its clients with: “The right flash for the right performance at the right price.”

IBM’s representatives explained that the updates were made possible by the fact that the prices of flash components have been dropping at a rapid pace while reliability is on the rise.  The SSD Guy couldn’t agree more.

Here’s what IBM announced:

Starting from the low end and moving up, the V5030F entry-level/midrange array is an Continue reading

IBM Makes Flash Even Faster

IBM Edge ConferenceAt IBM’s Edge 2013 conference last week the company not only extolled the values of flash, as does anyone who has had a flash experience, but it also showed how flash could be made even faster than it already is.

You’re probably already thinking: “Flash is about 1,000 times as fast as HDD – how do you make it even faster?”

The answer is actually pretty simple: compress the data.  If there is a limit to how much bandwidth you have going into and out of a piece of storage, you can speed it up if you can reduce the size of the data that consumes that bandwidth.

Of course, that’s not always easy.  Compression often slows data access down, even for HDDs, and it could Continue reading
