HPE Nimble Storage Connection Manager
When you deploy VMware ESXi on HPE Nimble Storage arrays, you must install the HPE Nimble Storage Connection Manager (NCM) on the ESXi host. NCM consists of the HPE Nimble Storage Connection Service (NCS) and the HPE Nimble Storage path selection policy (PSP). NCS is essential for optimizing iSCSI sessions from the ESXi host to the HPE Nimble Storage storage group. The PSP optimizes I/O multipathing.
Note: Prior to vSphere 6, VMware required
enterprise-level licensing for the use of third-party multipathing solutions such as the
HPE Nimble Storage PSP. For vSphere 6, this functionality is supported with the standard
license.
