Changing the host protocol in the E5600 or EF560 by replacing
hardware components
This documents applies to E5600 storage arrays, including the E5612, E5624, and E5660, and the EF560 flash arrays.
The following image shows all the protocol changes that are possible:
*If you are converting between Fibre Channel and iSCSI, you must use the host interface card (HIC) feature pack conversion
documents, not the procedures in this document.
**If you are converting from iSCSI to SAS or InfiniBand (IB), you might need to swap only the HICs or the controllers and
HICs as a unit, depending on your Replacement Part Number. You can find the instructions for determining the Replacement
Part Number in this document.
For other changes to the HIC protocol, you might need to perform both a HIC hardware upgrade and a HIC feature pack
conversion, or you might be able to perform a HIC feature pack conversion only. For example, if you want to change the
protocol from Fibre Channel to IB, and you want to use iSCSI RDMA Protocol (SRP) instead of iSCSI Extensions for Remote
Direct Memory Access (iSER), you must follow a two-step process:
1. Perform a HIC hardware upgrade to IB-iSER.
2. Perform a HIC feature pack conversion to convert the IB HICs from iSER to SRP.
This document describes how to perform HIC hardware upgrades only; for instructions for performing HIC feature
Note:
pack conversions, see the list of related documents at the end of this topic.
Considerations for this procedure
Before starting the procedure, be aware of the following:
• Because the power is off, you must schedule a downtime maintenance window for this procedure, and you cannot access
data on the storage array or flash array until you have successfully completed the upgrade.
