CentOS - Aug 2007 - Who does snapshots other than Network Appliance?

Having snapshot technology is great.   Who else supports it?

Thanks.

Try EqualLogic.  I'm pretty sure they do snapshots.

Thanks,

it can be done at two levels, file system or block.

many SAN (block level) devices have snapshots, including most of the LSI 
Logic Engenio stuff (resold by IBM, Sun, others), EMC, Intransa, 
Equalogic, etc.

NAS devices are really just file servers, so could have snapshot 
implemented either in their backing block storage devices or as a 
feature of their volume management or file system.    NetworkAppliance 
supports this natively, so do generic OS's like Linux (with LVM), 
Solaris (with ZFS), which are often used as the innards of NAS systems.

EMC supports several levels of snaps with their SnapView layered product.? See
their product page at http://www.emc.com/products/software/snapview2.jsp

We didn't buy it, but that's because we are only doing VMware ESX direct
attached hosts, with a single host per CLARiiON, and I'm using VMware's
snapshots for those instances where I need snaps.? Not getting SnapView meant I
could get more terabytes.
