|
A physical SteelFusion Core supports the following network/storage protocols? |
iSCSI |
|
|
A virtual SteelFusion Core supports the following network/storage protocols? |
iSCSI & FC |
|
|
Type of Core VE Fibre Channel LUNs? |
FC with RDM (Fiber Channel with Raw Device Mapping) |
|
|
Fibre Channel LUNs are distinct from iSCSI LUNs in these ways: |
- No MIPO - SCSI reservations are not taken on the FC LUNs - Additional HA configuration required, each appliance must be deployed on a seperate ESXi system for failover peers - Maximum 60 Fibre Channel LUNs per ESXi system, ESXi allows a max of 60 RDMs into a VM. Within the VM an RDM is presented as a virtual SCSI device. |
|
|
Where do you configure LUNs in the Core? |
Configure -> Manage -> LUNs |
|
|
Where do you configure iSCSI? |
Configure -> Storage Array -> ISCSI, Initiators, MPIO |
|
|

iSCSI target - as the edge holds the data. |
|
|
