Windows Server 2012 Storage: Windows Gets a Bit SANer Presented by Mark Minasi firstname.lastname@example.org @mminasi on twitter 1 V2.00. contents copyright 2013 Mark Minasi. Copying and redistribution is strictly forbidden. Thank you for respecting our copyrights.
Windows Clusters Basic Prototype 9 shared storage Two or more SQL, Hyper-V, file etc. servers attached to the shared storage acting as "nodes" in the "cluster" SQL databases, virtual machine disks (VHDs), DHCP scopes, regular old files, etc Shared storage allowing both systems to do block I/O on the same sectors… iSCSI One of the servers actually reads/writes the shared storage and is the "active" node; the others just wait for the active one to die, and they're the "passive" nodes. In a few special cases, all nodes are simultaneously active; need R2 or 2012 for that
What a SAN Does 12 Take a bunch of actual disks… Clump them together into what now looks like a single big pool of storage…
What a SAN Does 13 And SANs then let us carve out pieces of the pool called "LUNs" which look like actual physical hard drives… Each of which is available to a server that understands how to speak the iSCSI protocol, which lets us talk SCSI over TCP/IP. The server thinks it's a physical hard disk that it's talking to.
