There were plenty of announcements at Pure//Accelerate in Austin this past week and we were given a preview of them at a StorageFieldDay Exclusive (SFDx), the day before the announcement.
First up is Pure’s DirectMemory. They have added Optane SSDs to FlashArray//X to be used as a read cache for customer data. As you may know, Pure already has an NVRAM write cache. With DirectMemory, customers can have 3TB or 6TB of Optane storage in a FlashArray//X70 or //X90 storage. It almost looks plug and play, you take out one or two flash modules and plug in Optane SSD(s) and off it goes. DirectMemory went GA at the show.
Pure also announced FlashArray//C at Accelerate. This is a new capacity optimized storage solution. They have re-designed their flash module to support higher capacity flash, and supply higher capacity storage (targeted for QLC flash but will originally ship with TLC). FlashArray//C supplies ~5PB of effective (~1.4PB raw) capacity in 9U. Although, FlashArray//C offers cheaper storage on $/GB basis it is also much slower (RT latency on order of 2-4msec) than FlashArray//X storage.. Pure like other vendors we have talked with are trying to drive disk technology out of the enterprise. We had some interesting discussions with Pure (and others) on this topic at the reception. Just remember, tape is still alive and well in the enterprise AND cloud, 52 years after being pronounced dead.
Pure had announced CloudBlockStore (CBS) previously but it is now GA through partners or on AWS marketplace. Give them kudos for their approach as they have taken a different approach to Pure storage in the cloud. With CBS, they have effectively re-archetected and re-implemented Pure FlashArray using AWS EC2, IO1, EBS and S3 storage and ended up with a highly available (iSCSI) block software defined storage. It will be interesting to see how well it’s adopted. Picture is from me explaining CBS architecture to @DVellante.
For Pure’s FlashBlade storage, they have doubled the number of blades in a cluster (or name space), from 75 to 150 FlashBlades. Each FlashBlade contains storage and compute (almost computational storage), so one should see an increase in bandwidth with the added blades. None at Pure would go on record with specific numbers on any performance improvement because it’s still undergoing testing.
Finally, FlashArray//X will offer full NFS and SMB file support. This is coming from a recent acquisition (Compuverde). They plan to differentiate between file on FlashArraiy//X file storage and FlashBlade by saying that FlashArray//X file is for those customers with mostly block storage requirements but also need small amount of file storage and FlashBlade for everyone else that needs file.
The podcast is ~23 minutes. Keith is a long time friend and co-host of our GreyBeards On Storage podcast. He’s always got an interesting perspective on how new technology can benefit the data center today. Listen to the podcast to learn more.
