EMC made two DMX-4 announcements today. At the top end, the first details solid state drives which replace standard spinning HDDs. At the bottom end the second announces new 1TB SATA-II drives (and other miscellaneous stuff).
The solid state hard drive (or as Chuck Hollis describes it, the enterprise flash drive), isn’t just a small 1-2GB device; this is a real replacement for 73GB or 146GB drives and will apparently slot right into a standard HDD bay. Assuming drive support is identical to standard HDDs, then it should be possible to create hypers from the drive(s) and present them to many separate hosts. I see this as significantly better than products such as Tera-RamSan. Firstly, the EMC device is more compact, second and most important, it integrates with the existing array, meaning better compatibility, support for existing functionality such as SRDF and TimeFinder and therefore more consistency.
Obviously a real issue will be cost versus standard HDDs, however I think there will be plenty of takers. Every large organisation has one or more application which needs more storage horsepower and the tradeoff between rewriting the application, purchasing more hardware or using SSD HDDs in DMX will make the latter option very appealing. Hopefully as time goes on, the cost of SSD drives will reduce significantly (think of how expensive SD cards used to be) and SSD technology will be more attractive to a wider audience.
Naturally the blog spin masters at EMC have been active; here’s just a selection of the links I found:
Nothing yet from The Storage Anarchist though. Give it time…
The second announcement covered availability of 1TB for DMX-4. Fair play to EMC, they are offering storage technology across the spectrum of speeds and capacities, all in a single box. I still need to think through the implications of having even more choice in one array, not least of which is the impact on my design methodologies!
Oh and the second announcement re-announced thin provisioning for DMX-4. But everyone else is already doing that already.
