When I initially ordered this host, I wanted to equip it with 4 x 4TB Drives in a RAID 5 and leave it at that. But management thought we wouldn't use this server like we have "for awhile" and that by then buying hard drives would be feasible. So I was forced to use old enterprise drives we had lying around. This happened to be 4 x 1TB hard drives.
Well after a year of having this host and putting it into production and getting major use out of it, we are now approved "to do whatever to get this thing running like it use to". So I got 4 x 4TB drives and a ram kit and am all set as far as hardware goes. For software, we will be moving from a 5.1 license to a 5.5 license and take advantage of the web client because I hate firing up windows to just manage the host.
Now, the problem I run into is moving this data from the RAID to an external drive. My best option is to use another drive via Internal Sata, have it show up in vSphere client, and copy data that way or log into the shell and CP the data from one "datastore" to the other "datastore" which would be the external drive hooked up via internal sata.
The question I have is, is there a better way to do this? I used Veeam to backup a VM that was shutdown and 50gbs with 24gbs being used and it said speed of the copy was "20MB/s" over ethernet and the bottleneck was "source". This was while the host was up and running about 26 VMs and actively being used. I figured the best and fastest way to backup and do this upgrade would be using a physical drive and hooking it up to the host.
I also would like to know if installing ESXi to a flash drive is a recommendation for production use. I know its preferred by many and especially since ESXi runs in memory and writes to the drive every 10 minutes. But I'm not sure how liable it is. I know that all I have to do is replace the bad flash drive with a good one, rescan for data stores, manually add the VMs into inventory and turn them on. I just don't know what I'm expecting as far as life of the drive? I plan on buying a good brand drive like PNY or Corsair or Kingston Data Travelers. Just some input would be nice
If anyone has any suggestions at all please pitch in. Im trying to minimize this to a 1 week downtime. I really wish management would let me buy another host so I have a proper ESXi setup and not a ghetto / home setup but oh well, thats the least of my problems.
Thanks for reading!
