iSCSI Cake, www.iscsicake.com, is a Windows based iSCSI target which shares server's disk, partition, VMDK file, cluster, ESX or ISO file with iSCSI initiators/clients. iSCSI Cake provides another choice for enterprise storage virtualization. Client can access remote iSCSI storage as local disk, which supports all disk operations such as partitioning, formatting, read, and write. iSCSI Cake uses copy-on-write mechanism to handle client write requests which means client can write, delete, format and repartition iSCSI disk without changing any bytes in server's storage resource.
