You'll be hard pressed to find one that isn't. Having a PC input doesn't instantly make a TV set sub standard in some way. The only thing you'll struggle with is aspect ratio. Unless your laptop has a widescreen display, you may find yourself with a strange sized desktop on your TV. That said, it's never been a major problem for me personally. Just play around with the resolution until you find one that suits both. Just buy the best model you can afford. If this is to be your main TV set as well, try and get one with a true HD panel.

Message-ID: Ah yes, now I remember! I've double checked and the community edition does offer iSCSI (and fibre if you wish!). A quick look online I see a few results showing Nexenta is faster than OpenFiler on the iSCSI. After all it is ZFS under the hood, so it's professional level from the ground up. Nexenta (and any ZFS based systems) recommend you don't use hardware raid so you won't be missing anything by not having a card.

Message-ID: Hi Stuart, I'm using the community edition of nexentastor 3.1.1 & its currently connected to a ESXi cluster via iSCSI. The "community" edition has a few limitations around iSCSI but it works fine for a Lab. In theory you should see adequate read performance with 8GB ram coupled with the zfs adaptive read cache. I guess just try it and see, load 3.1.1 & bonnie. All the best, Thomas.

Message-ID: HIya, I did actually change from blockio to fileio and that brought the speed issue under better control. Just before you posted I am moving my important vms from the san to local storage. At that point I am going to blow away the SAN and reinstall it with Nexenta. To reduce the overhead I am tempted to try NFS also. It will take about several hours to copy the 500 GB vm image across. What is interesting is that Nextenta actually mention this box as a soho san, but when you have your DC, VCenter and additional VM, the IO seems to swamp the processor. I can only think it may be the linux software raid. I did try the onboard raid, but Linux ignored it completely ;). Tried it on basis that hardware raid (or hardware assisted raid) may reduce IO commands on processor. Anyhows, will report back.....

I am suddenly very confused. I've put a file on a tmpfs with some random content in /media/FILE for a very unscientific test. I've got /var on lvm on top of an mdadm raid1 of two SATA disks. When I dd from /media/FILE to /var or when I read back from it I get nearly 75MB/s. Fair enough (for me!) However, when I remove a partition from the RAID and write directly to it I get 2.4 MB/s. iotop says there is no other appreciable IO. top says dd is the only real CPU user: #mdadm --fail /dev/md1 /dev/sdb5 mdadm: set /dev/sdb5 faulty in /dev/md1 #mdadm --remove /dev/md1 /dev/sdb5 mdadm: hot removed /dev/sdb5 from /dev/md1 #dd if=/media/FILE of=/dev/sdb5& [2] 2206 #killall -USR1 dd 839856+0 records in 839856+0 records out 430006272 bytes (430 MB) copied, 180.702 s, 2.4 MB/s What am I missing here? Why would it copy so slowly to the raw disk partition? Right now I'm getting over 70MB/s with the RAID resyncing.

You can also give FreeNAS a go, that will do ZFS and iSCSI, however they're not as closely linked as the iSCSI isn't part of their ZFS implementation.
