Good day. We have an AFF a220 and we are concern with hosting a VM on it via vSphere that has a Windows database application, PostgreSQL, that could potentially shorten the lifetime of the SAN. We realize that SSD drives have a limited number of writes however the SANs like the AFF models are optimized to mitigate the number of writes to disk required. At least from reading this article (Optimized Write Performance):

1) Should we be concerned about hosting our database app VM on the SAN and wearing out our SAN disks sooner?
2) If so, do you have any recommendations for SAN configuration such as RAID mode that may lengthen the lifetime of the SSDs in the SAN to mitigate the increased number of writes?
thank you in advance!
