And that’s a problem when you’re in the middle of an outage (planned or unplanned) and any of that infrastructure is a VM. Auto Deploy is an interesting VMware feature but it relies on a functioning network, DHCP & PXE & TFTP, DNS, and vCenter infrastructure to work.
That isn’t the most productive use of my expensive drive bays (and data center space).ģ. Say that I do want to put local disk in my servers, be it some SSD so I can do caching (a la SanDisk Flashsoft, PernixData, vFRC, etc.) or maybe do VSAN, I’d have to use two of my limited drive bays for boot volumes. Anybody that argues that the H330 is fine ought to be okay with the mirroring the Internal Dual SD Module does, because the two are about equal in that regard.Ģ. To start, it isn’t even certified for VMware VSAN. To head off the inevitable comment: the PERC H310/H330 is not a decent RAID controller. In contrast, the Dell Internal Dual SD Module is $104.60 per server with two 16 GB SD cards. On a 32 node cluster that’s $37,184.96, or the cost of three servers, over five years. Labor costs dealing with drive replacements, monitoring, etc.: $200.00 (this is low). Power for this setup, at 5.9 Watts per drive (as per Tom’s Hardware), guestimating 5.9 Watts for the RAID controller, and $0.14133 per kWh in my locale: $109.60 for 5 years. Looking at, if I outfit a Dell PowerEdge R630 with a traditional setup of two magnetic disks and a decent RAID controller my costs are: SD cards aren’t all that reliable, and there are other technologies to get a hypervisor like ESXi on a host.
Id think a person like you would know to use autodeploy.”Īside from that fellow’s malfunctioning apostrophe, he has a good, if blunt, point. “SD cards are NOT reliable and you are putting youre infrastructure at risk. They’ve ranged from why would you use an SD card in a server. I’ve had four interactions now regarding my post on replacing a failed SD card in one of my servers.
