I am working on a project to determine new markets/applications to support
enterprise level, Solid State Disk (SSD) devices. It appears virtualized
servers supporting I/O intensive applications can experience performance degradation
caused by the storage system. Would a SSD solution that delivers very
high IOPS (400,000 +) be a viable solution for larger VMware installations,
possible in Data Centers? This solution would provide another option than
purchasing a storage upgrade or more likely a new storage server. If
"yes" how influential would VMware users be in the evaluation and
purchase process of such a device?
a) Somewhat influential
b) Influential
c) Very influential
While SA, DBA, etc. are typically involved in this process, understanding the
user's involvement would also help in determining if sales and marketing programs to VMware
customers makes sense. If there are other communities you could recommend
for feedback, please let me know.
Thanks,
Randy
RSSD,
The VMware administrator is going to have about as much influence as any other systems administrator. In other words, that's not who you want to be marketing to. You need to identify the business owner who is responsible for delivering the business value to the bottom line, and that's who you need to be marketing to (or at least to their technical advisors).
SSD technology can be compelling - in the right situations. I don't think you're going to see a demand for it outside of a good sized datacenter, simply because most smaller companies don't have a need for the number of IOPS that SSD can deliver (and that's what justifies the cost of SSD, isn't it?). Most environments are going to already have "enterprise class" storage solutions and might be interested in enhancing what they have with some tiered SSD capabilities. This could meet the IOPS need and free up a lot of the spindles that were purchased just to meet the throughput demand (rather than the capacity demand).
In short, you're hawking enterprise class technology. You need to be selling to the right person, and that person is likely not spending their days in a datacenter (or managing day to day operations in a datacenter).

The Enterprise Storage is made by several part, like for example:
type of disk
type of RAID
storage cache
type of storage processor failover and type of MPIO
SAN bandwidth
SAN topology and switches type
type of HBA
For this reason the disk type itself could (IMHO) only be "Somewhat influential".
Only without any bottleneck (but you probably need a FC 8Gbs SAN with good storage and switches) could be "Very influential".

At this point I would place SSD as my main Enterprise storage as 'Detrimental'. They simply lack the wide use and long term analysis is performance and real world MTBF.
Would I like to try them on less critical systems? absolutely.
They are also very hard to justify on a ROI perspective. I'd hate to be the one standing in front of the CEO to tell him that I'll be spending more for less storage of an unproven technology.
Andre,
Thank you for the response.

Asher,
Thank you for the feedback. Excluding the technical aspects of the
device that may not meet your requirements, my inquiry was to better understand
the VMware user from a sales/marketing perspective. For example, what
influence does VMware user have if his VM supporting an OLTP application does
not meet the SLA? Does the decision to recommend/purchase another performance solution rely solely on the SA, DBA or other?
We can assume there are environments in which the end user(s) are the
decision makers.
The end goal is to better understand the target audience and what messaging is
most appropriate for this type of solution to VMware users.
Thanks,
Randy

Ken,
Thank you for the response. Your feedback is on right on the mark for the type of information I am requesting.
Enjoy the weekend...
