Summary
DAS, NFS, FC, iSCSI, FCoE (HW&SW), vFRC, SDDC
Details
vSphere 6.0 adds:
- Virtual SAN 6.0
- Virtual Volumes (VVOL)
- NFS 4.1 client
- NFS and iSCSI IPV6 support
- Storage Based Policy Management (SPBM) now available in all vSphere editions
- SIOC IOPS Reservations
- vSphere Replication
- Support for 2000 virtual machines per vCenter Server
vSphere 5.5 adds:
- End-to-End 16Gb FC support: Both the HBAs and array controllers can run at 16Gb as long as the FC switch between the initiator and target supports it.
- vSphere Flash Read Cache that enables the pooling of multiple Flash-based devices into a single consumable vSphere construct called vSphere Flash Resource, replacing the previous Swap to SSD feature
- prior to vSphere 5.5 storage supported in MSCS environments was Fibre Channel (FC). With the vSphere 5.5 release, this restriction has been relaxed to include support for FCoE and iSCSI.
vSphere 5.1 added support for 16Gb HBA (prior to 5.1 you could use them but only at 8Gb speed) - still, in vSphere 5.1 there was no support for full, end-to-end 16Gb connectivity from host to array, to get full bandwidth, a number of 8Gb
connections must be created from the switch to the storage array
- vSphere 5.0 added SSD handling and optimization. The VMkernel automatically recognizes and tags SSD devices that are local to an ESXi host or are on the network. In addition, the VMkernel scheduler is modified to allow ESXi swap to extend to local or network SSD devices, which enables memory over commitment and minimizes performance impact.
- vSphere 5.0 also introduced a software FCoE adaptor. The software FCoE adaptor will require a network adaptor that can support partial FCoE offload capabilities before it can be enabled.
