Hi, I'm looking at using Linux as a NAS / SAN device, and would like some input from other's who have done this before? How would it compare to commercial SAN devices, Thecus N8800SAS (http://www.thecus.com/products_over.php?cid=11&pid=177&set_language=english) or something similar to these? I would probably use hardware RAID 10, and could go with either SAS / SATA, and then probably offer iSCSI, Samba. NFS & rsync. In terms of servers hardware, well either Tyan / SuperMicro / Intel / Dell would be fine as well. But, my question is rather from a linux point of view, how would Linux compare to dedicated NAS devices, in terms of the OS managing the device? -- Kind Regards Rudi Ahlers CEO, SoftDux Hosting Web: http://www.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Of course you wouldn't know they ran Debian or linux unless you tried to telnet to them on port 22 and saw the SSH banner. http://www.3par.com/inservtclass/ My active-active NAS head units runs CentOS 4.4 on IBM hardware (back end disk storage provided by above array) http://www.exanet.com/default.asp?contentID=209> How would it compare to commercial SAN devices, Thecus N8800SAS > (http://www.thecus.com/products_over.php?cid=11&pid=177&set_language=english) > or something similar to these? > > I would probably use hardware RAID 10, and could go with either SAS / > SATA, and then probably offer iSCSI, Samba.

I used openfiler about 1.5 years ago mostly for iSCSI and it worked ok, at one point had 4 shelves of HP MSA SCSI disk drives attached to it each connected to dedicated RAID cards on an older HP DL585. I'm looking to get a Thecus N770 myself pretty soon, mainly for the smaller integrated form factor with many drive bays. nate

I had a simarly question: building one self, or buyding dedicated hw. Looked through several specs of different boxes, and decided for an ICY-box, that can hold two sata-disks, raid0/raid1/jbod, has an GB-ethernet interface and capable of doing NFS. (which is actually an Linux-box) However, the box is as slow as a proverbial civil-servant, although the link is realy set to GB, it just might as well have been 100MB. And even that its not capable of filling to the max. (60Mb) Found out (afterwards ;-) on the relevant product mailing lists that it's the max the box can do. hans ______________________________________________________________________ Dit bericht kan informatie bevatten die niet voor u is bestemd.
