- Chris M Evans over at ArchitectingIT has a good post on why he doesn’t want to see a ten year old flash array. I honestly don’t think to many organisations really keep ancient arrays around as their primary storage array, the support costs alone would be astronomical.
- Speaking of flash, the VMware vSphere blog has a useful post on VSAN hardware guidance with SSDs. I’ve linked to the first part in the series. I think I’ll be holding off till the next generation of servers come out, sometime this year (2014).
- With all the brouhaha about VSAN (and I admit I’m looking very hard at it and how much it would cost to get a nice home lab setup) the requirement for one SSD per disk group should show the importance of SSD reliability. If you plan on using consumer grade SSDs or SSDs not from your hardware OEM (and even then) you are going to want to test them, hard. With that I would really recommend reading the “Analysis of SSD Reliability during power-outages” report. I hope more tests like these are performed.
