UPS fails from (Environmental, battery leak, someone forgot to service it). Said poor idiot does a hard reset of the wrong server at the IMPI/iDRAC/iLO basis.ġ0. Some poor idiot does a hard reset of the server to the wrong hypervisor.ĩ. PSU bridge failure (Seen this happen in a TwinServer frame so the 'redundant' power become non-redundant and failed).Ĩ. PSU failure (especially if non-redudant)ħ. Motherboard failure, causing server to power off).Ħ. Midplane reset (if using more than 8 drives per PHY)ĥ. HBA or Controller reset, or failure that drops power if power to drive was contengent on power coming from SAS 8087.Ĥ. Server straight up crashes (Purple/screen/Blue Screen causing a non-planned reboot that drops power to the drives)ģ.

Someone trips over the power cable (This happens a lot more than you'd think)Ģ. Just what I've seen in the field? Here's a random 10 I've actually seen happen.ġ. Short of that, what else would be a factor? Storage Ninja, I hear you, but if it's a matter of 'power' being an issue, a stop by Walmart or Best Buy will yield you a UPS. Careful with power loss protection on them. Pop in a decent sized SSD (I prefer Samsung pros).OS X itself doesn't support iSCSI (not that you would need it for this as it would sit on VMFS which should be fine). Get a Sonnet Thunderbolt to PCIe adapter & Fiber card, or Attotech, need to research what is usable at the (ESXi) hypervisor level. This sounds crazy, but hey, it's one way to deal with crazy licensing requirements.ĭavid_CSG wrote:At the same time, you can’t create a software raid in OS X & yet then install ESXi, that’d nullify the OS & software RAID. I've done this before with a game developer.Īt large scale I've seen someone use ATTO's Drive carriers to hold drives for vSAN with MacPro's. You can put a FC HBA on a Pro (Someone make them) to do shared VMFS between MacPro's. VMware internally has MacMini build farms (No they are not offically supported, but yes they work).Ĥ. For one off development Fusion isn't bad as a type 2.ģ. ESXi is the only serious type 1 hypervisor I've seen running Mac OS X VM's.Ģ.
