I was told last year by HPE tech support this is the correct part number to buy if we want to upgrade to 2050:
HPE MSA 2050 SAN Dual Controller SFF Storage Q1J01A
NOTE: Includes an SFF Array Chassis, two MSA 2050 SAN controllers, two AC power supplies, two .7m PDU cords (IEC C14), one rack-mount kit.
Is an equivalent 1050 part number available that will take the SFF disks presently used in our 2040 SAN?? -- is this even possible??
Thank you, Tom
