We have EMC VNX 5100. In that we populated 75 drives and now we want to add two more disk shelves based on the business requirement. I know VNX 5100 supports maximum of 75 drives. Is there a way to change/upgrade the VNX5300's SP like NetApp's Head Swap? meaning only replace hardware portion of 5100's DPE with 5300's SP unit along with existing disk shelves.Please suggest me on this.
Within the same generation though (which I believe you asked about: VNX 5100 to VNX 5300), there is an option to do a DIP (Data in Place) conversion from VNX5100 (Block) to a larger VNX configuration such as VNX5300 (Block). It requires a service window and downtime to complete, but yes as you noted it would involve, amongst other tasks, swapping SP's.
