Proprietary solution...
Each time I discover another feature on our Isilon iQ 6000 it is deceptive.
For example when you replace an hard drive that is faulty, the reconstruction is all but automagic, you have to enter "isi devices" command by hand on the console, with a risk of human-error (ie: not formating the new hard-drive but another). Terrific!
Moreover, the "famous" OneFS file system that span across a cluster of 5 boxes and 60 hard-drives, that deliver the bandwidth of one good SSD drive on a bsic PC (sic), seems not to be able to use bigger hard-drive when you have a mix, so 80's!
I changed one of the consumer-grade 500GB 7200rpm Hitachi Deskstar that
came within a node (they only use consumer grade hard-drive, not
server-grade, the server-grade you will have it on the billing price of
an Isilon cluster not on it's component!), that has failed and replaced
it by a 1000GB (1TB) 7200rpm SATA hard-drive, and guess what?
The capacity remains the same in the node, only recognizing it as a 500GB hard-drive with 5 logical partitions.
Does OneFS be limited to one-size hard-drive on a box or on a cluster?
Even desktop NAS haven't this kind of limitation anymore, spreading datas (and copies) on many drives of different sizes.
Does ISILON limits usage of their Cluster to force customer to buy new ones when one is full?
(instead of buying inexpensive high-capacity hard-drives and raising 2X to 4X the capacity of their existing system)
Anyway, OneFS & ISILON is a proprietary system, with programmed-obsolescence...

EXANET - Superior Alternative
Good day to all,
I have read this blog, and would like to share thoughts about, what I believe, is a superior alternative to many NAS solutions out there, including Isilon. We have been a specialized storage integrator for 17-years, and have found a couple of years ago a pretty impressive clustered and redundant NAS solution called Exanet. Most places we competed against Isilon we won with Exanet on performance, features, and ease of use. It support simultaneously CIFS, NFS, and AFS (Mac)natively, and can scale linearly both in nodes and capacity. Give me a call to discuss (514) 335-3050 x-104.
