Just came to my attention that EMC is finally joining the SPC (Storage Performance Council). As I’ve pointed in their past, their absence from this most standard industry benchmark was puzzling, kudos for rectifying this omission.
I do have some advice for EMC (and all other vendors that have already posted results):
- Do show results for your various supported RAID types, not just RAID10 – after all, if most of your customers don’t just deploy RAID10, it makes sense to show RAID5 and RAID6, especially if you want to compare results with NetApp RAID-DP (that’s the protection equivalent of RAID6). This will increase your credibility. The argument that you only show RAID10 since that’s the best performing doesn’t hold water – everyone knows the other RAID types will have different performance levels, providing results for everything will at least enable customers to get an idea of how much of a performance hit they’ll have with the different RAID types with a write-intensive workload.
- Do show long-running benchmarks with auto-tiering enabled. After all, if you are claiming your auto-tiering implementation doesn’t hurt and can even improve results, this is your chance to show it.
- Enable features like snapshots.
- Use your large cache if you have one, especially if you keep advertising that it accelerates writes. It will just solidify your claims.
Welcome to the club!
