2012 Server - Microsoft iSCSI Software Target 3.3

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:

• Provide shared storage for Hyper-V to enable high availability and live migration
• Consolidate storage for multiple application servers (i.e. Microsoft SQL Server or Hyper-V)
• Provide shared storage for applications hosted on a Windows failover cluster
• Enable diskless computers to boot remotely from a single operating system image using iSCSI

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.

----------------

Microsoft ha messo a disposizione gratuitamente un target iSCSI, chiamato Microsoft iSCSI Software Target, al momento disponibile nella versione 3.3.

Di iSCSI si parla quando parliamo della Live Migration di macchine virtuali su Hyper-V sfruttando un volume CSV (Cluster Shared Volume). 

Microsoft iSCSI Software Target consente di esporre i dischi collegati ad un server come LUN accessibili via rete tramite appunto il protocollo iSCSI.

L’utilizzo insieme ad Hyper-V e in particolare l’attivazione dei Cluster Shared Volumes e l’utilizzo del MultiPath IO (MPIO) consente di abilitare scenari di alta disponibilità con Live Migration molto rapida delle macchine virtuali. Infatti, l’utilizzo di uno storage CSV su LUN iSCSI consente a tutti i nodi del cluster di vedere nello stesso momento il disco base della/e Virtual Machine, non rendendo necessario lo spostamento del disco da un host di virtualizzazione ad un altro.
