Host port protocol conversion

You can convert the protocol of a host to a different protocol so that compatibility and communication can be
established.

Overview and requirements

Learn about the requirements you need to know about before converting the host protocol.

Requirements for changing the host protocol

Learn about the requirements you need to keep in mind when changing the host port protocol.
• You have scheduled a downtime maintenance window for this procedure.
• You must stop host I/O operations when you perform the conversion. You cannot access data on the storage
array until you have successfully completed the conversion.
• You are using out-of-band management. (You cannot use in-band management to complete this
procedure.)
• You have obtained the necessary hardware for the conversion. Your Fujitsu Sales Representative can help
you determine what hardware you need and help you order the correct parts.
• Dual-protocol SFP transceivers support both FC (at 4 Gbps, 8 Gbps, 16 Gbps,) and iSCSI (at 10 Gbps), but
they do not support 1 Gbps iSCSI.
This section describes how to change the host port protocol for the following controller shelves:
• AB6100 controller shelf

Change host protocol

If you have an Infiniband (IB) HIC, you can convert the protocol of the IB HIC from NVMe to InfiniBand, or from
NVMe to RoCE.

Determine whether you have dual-protocol SFPs

You can use SANtricity System Manager to determine what type of SFP transceivers you have. Because these
SFPs can be used with both FC and iSCSI protocols, they are referred to as dual-protocol or unified SFPs.
Procedure
1. From SANtricity System Manager, select Support.
2. Select the Support Center tile.
3. On the Support Resources tab, locate and select the Storage Array Profile link.
4. Type SFP in the text box, and click Find.
5. For each SFP listed in the Storage Array Profile, locate the entry for Supported data rate(s).
6. Refer to the table to determine whether you can reuse the SFPs, as follows:
