Complementing other elements of your IT Infrastructure
You can incorporate DataCore storage virtualization software into your existing IT infrastructure with the confidence that it is compatible with the other software and hardware elements of your environment. That compatibility is achieved through strict adherence to standard interfaces well established in the industry. The software has been designed and coded to be hardware and operating system independent.
From each host’s perspective, DataCore presents virtual disks that appear to be well behaved, logical disk drives with ideal characteristics. To the physical storage devices under DataCore’s virtualization control, the software appears to be a well behaved application consuming disk capacity.
In the most typical scenario, the DataCore software is installed on a pair of standard Windows servers inserted between your server farm and the physical storage devices. These two dedicated servers take on the specialized role as DataCore storage virtualization nodes. The DataCore nodes thus front-end the physical storage pool on behalf of the server farm to cache disk I/O’s and to transparently perform all the added value storage virtualization functions, including mirroring and replication.
Disks that were formerly locally-attached to the servers in the farm will be disconnected and re-attached to the DataCore nodes. Internal disks are usually combined in trays (disk shelves) for better mechanical organization. External SAN connected disks will be rezoned to connect only to the DataCore nodes.
The servers in the farm will either use Ethernet NICs for iSCSI connections to the SAN or Fibre Channel host-bus adapters (HBAs). These will be zoned to connect only to the DataCore nodes. That is, they are no longer directly accessed by the server farm.
