So the FAST suite is available on Clariion. Good news !! If you don’t know what FAST (Fully Automated Storage Tiering) is, in a nutshell it’s automated storage tiering (as implied in the name), it ensures that LUNs which may have critical performance requirements and variable characteristics in terms of IO utilisation are using disk as efficiently as possible. LUNs of data which are accessed frequently will be serviced by one tier of disk (ie solid state) and others by another (ie fiber channel disk or SATA) and all this is done dynamically on the fly using the Clariion Virtual LUN technology (meaning you can migrate a LUN from 1 set of disks to another seamlessly to the application and retaining all the properties of the LUN); All this is done on the automatically using FAST. This is especially relevant now as virtualisation is rife and the ability to be so flexible by way of server deployment requires that the storage is either meticulously designed and frequently reviewed, adjusted, etc or the storage platform is adaptive and flexible (even more relevant in multi-tenancy environments which offer a managed service) . FAST enables EMC storage to fall under the latter.
So, is there a sting in the tail ? is it silly money ? much like Control Center was (although that did get better to be fair).. surprisingly… no. The FAST suite of tools is suprisingly well priced at a touch over £6000 list. Bearing in mind that the FAST suite isn’t just the FAST software, it also includes Navisphere Analyser (for analyzing and monitoring SAN bandwidth and IO), QOS Manager (for performance tuning) and they throw in an assessment service to provide recommendations as to which LUNs are most suitable for migration to fast managed LUNs which will utilise EFD (solid state drives to the rest of us) and/or SATA etc.. (I’ll come back to why this is required a but later) considering that you’re looking at a £10k list price for Navisphere Analyser and QOS Manager alone, thats not a bad deal. But then it wouldn’t be as you’re still looking at just under £8000 for an enterprise flash drive and FAST is as good a mechanism as any to drive sales of solid state drives. But this isn’t just a smoke and mirrors mechanism to sell solid state drives, the benefits are real. The capital expenditure involved in deploying Enterprise flash drives with FAST may be undesirable to a lot of businesses, but the return on investment is again very real. The requirement to procure mass amounts of FC drives to support highly transactional databases is not gone, but certainly minimized, man hours required for certain laborious storage admin tasks is reduced (especially in environments may have applications with extremely variable disk loads), power and cooling requirements are reduced, the list goes on..
So why is there an assessment service ? can’t I just chuck everything on FAST managed LUNs and tell it to go do ?… Yes, you could. But Solid state drives are still expensive, so make the best use of them you can. So I might suggest that LUNs with a lesser performance requirement and predictable disk load characteristics sit on standard LUNs.
See below to see FAST on EMC’s VMax.. now just waiting for this on Clariion and Celerra (sub LUN level)
and before some boxing boff corrects me on my Muhammad Ali quotation in the post title. I know its “flout like a butterfly, sting like a bee”.. but cut me some slack, float didn’t quite fit.. call it creative license 😉
