In order to finish my Storage Features Survey, I have collected the responses from the community on how they view primary storage from a virtualization, enterprise worthy perspective.
Most Popular Enterprise Storage Feature Responses (rounded):
Multiple Controllers - 70% of Respondents
Thin Provisioning - 65% of Respondents
Replication Capabilities - 60% of Respondents
Snapshot Capabilities - 60% of Respondents
High Availability - 60% of Respondents
Non-Disruptive Upgrades - 60% of Respondents
VAAI Support - 55% of Respondents
RAID Support - 50% of Respondents
Flash Technology - 50% of Respondents
Capacity/Shelf Expansion -50% of Respondents
There wasn't any big surprises, but there were a couple interesting responses. One of the higher responses came in for "Replication Capabilities", I knew this would be popular, however I did not envision it being as high on the list, since there are many other technologies in the market that can tackle replication from a different level in the stack. i.e. Zerto, Veeam. The other popular response that was interesting was "Flash Technology" at the array level. I know flash is very popular right now, but as you might know it's not something I agree with 100% of the time. PernixData can use flash at the host level for storage performance and thus can negate the use of flash at the array. I'm not saying this is the case for all environments, but it's enough to change the storage landscape.
The biggest response was for multiple controller support! This isn't surprising, since high availability & non-disruptive upgrades was also listed high on the list from respondents.
Did any of the responses surprise you or do you think this encompasses the most common requested enterprise features for primary storage?
Thanks for participating in the Storage Features Survey!
