VMware VAAI Support
SANOS 4.0 supports VMware VAAI functionality. VAAI is a set of APIs that allow ESXi hosts to offload specific virtual machine and storage management tasks to the SAN. With the support of SANOS 4.0 VAAI, it can offload the ESXi system overheads and as a result the ESXi system can reduce the usage of its CPU, memory, and storage fabric bandwidth. VAAI for iSCSI and FC supports Hardware Assisted Locking, Block Zero, Full Copy, and Thin Provisioning with space reclaim. Therefore, the XCubeSAM series can greatly enhance the performance of operations in a virtualized environment.
