    Connecting HP EVA disk shelf to "DIY"storage server

    Hi! I found a pretty good deal on a HP EVA 4400 disk shelf (model number AG638A I think) full with 300GB drives. I have a bunch of Qlogic FC cards and a random IBM server laying around so I was thinking this could be a pretty good storage setup for my offsite lab ESXi cluster. Basically what...

    VMware backup software for home lab

    Well, that's the idea! We run alot of stuff that you would normally see in a production environment. Losing them would just mean that we would have to set them up again, but we have some dirt-cheap dedicated servers in france that we use as our off-site target :) Thanks! I looked that up...

    VMware backup software for home lab

    We have about 60 VM's that we would like to keep backed up offsite. What (free) software do You recommend that we try/use, and why? We are running ESXi 5.5. Currently we have tried Bazaar VCB but we could not figure out how to connect that to vCenter, and connecting to each host was a bit of...

    Performance issue with ZFS and ESXi 5.5

    This is weird. After setting sync=enabled, then changing it back to sync=disabled, I now get the same awesome performance on 5.5 as on 5.1.

    Performance issue with ZFS and ESXi 5.5

    I have no ZIL device. I have already tried sync=disabled, and that did nothing. And when the two 5.5 servers were running 5.1 I did not have this issue.

    Performance issue with ZFS and ESXi 5.5

    Hello! I have been experiencing some issues with my ESXi environment. I have 2 ESXi 5.5 servers, one ESXi 5.1 server and one ZFS server running OmniOS. Datastores are mounted over NFS. On the two 5.5 servers the disk performance is really bad. Read speeds are normal, but writes are horrible...

    ZFS Very slow scrub performance

    I have found what "caused the problem"! It was the scrub priority setting. After setting it to... set zfs:zfs_scrub_delay = 0 ... It runs fast as heck! It completed 1TB in just 30min. And while I'm at it, I got a question regarding allocated space on my pool. It shows that there is 5.4TB...

    ZFS Very slow scrub performance

    I did download a few GB's (maybe 60 or so) of torrents. Could that really be enough to fragment the pool this bad? Also there are a few snaps, but not of the torrents I'm pretty sure. Pool is about 30% filled. I will try to remove the torrents of the pool and delete the snapshots, thanks...

    ZFS Very slow scrub performance

    I'm having some really shitty scrub performance with a new server I just finished setting up. Earlier when there was less data on the pool I saw scrub speed well over 450MB/s. Currently there is about 5.5TB on it and scrub is running at around 4MB/s. Its been running for about 7,5h now and...
