One common refrain we hear from you is that you appreciate the fact we’re driving down the costs of virtualization and adding more and more capabilities in the box such as Live Migration (LM) and High Availability (HA). We’re happy to do it and we’re just getting started. :) To use both LM and HA, these require shared storage. This shared storage can be in the forms of SAS, iSCSI or Fiber Channel SAN. For many environments this isn't an issue, but there are some specific scenarios where customers need LM and HA and the cost of a dedicated SAN is a blocker. For example,
Wouldn't it be great to have another option? We think so too. Today, as a big THANK YOU to our Windows Server 2008 R2 customers we are taking another step in lowering the barriers and making it even easier to take advantage of Windows Server 2008 R2 Hyper-V High Availability and Live Migration.
The Microsoft iSCSI Software Target 3.3 provides storage (disks) over a TCP/IP network. It turns a computer running Windows Server into a storage device which provides shared block storage. You can use Microsoft iSCSI Software Target 3.3 to perform a variety of storage-related tasks, including the following:
The Microsoft iSCSI Software Target 3.3 is an economical solution suited for a development or test environment and a small, medium, or branch office production environment. It enables storage consolidation and sharing on a Windows Server by implementing the iSCSI (Internet Small Computer Systems Interface) protocol, which supports SCSI-block access to a storage device over a TCP/IP network.
