Hi Everyone,We are in the process of purchasing a new SAN for our entire organization: SQL Server, file servers, VMs, etc. The consultants we are working with are recommending a solution which is entirely RAID5. The EMC VNX SAN would include 3 tiers of storage (SSDs, 10k SAS, 7.5k NL SAS) and automatically moves LUNs around based on the IOPS requirements. We'd also have the ability to "attach" a LUN to a specific tier if we wanted to. It will also have 400GB of FAST cache.Our primary database is our EHR and is 70GB right now, plus we have Great Plains and a number of other databases supporting IT infrastructure. All-in-all not a huge database footprint, but we keep adding more.Based on past experience (research and on the job) i have avoided RAID5 in the past because RAID10 simply had much better IO performance. I'm hesitant to just go with their recommendation since it represents a deviation from past experience and also what nearly every article says about SQL Server drive performance, but then again they have the expertise in new SAN tech.Just curious to hear what other folks have been doing and if in your humble opinion this seems like a logical solutionTIA!-Dan
