Release Notes

Fabric OS v7.3.0c Release Notes v1.0 Page 43 of 52
• Gatekeeper LUNs used by SYMAPI on the host for configuring SRDF/TF using in-band management
must be added to their containers with LUN state as “cleartext”, encryption policy as “cleartext” and
without “-newLUN” option.
• FOS7.2 and later supports KMIP key vault type for Thales e-Security Key Authority SW v4.0.0 KMIP
servers. Please refer to the KMIP Encryption Admin Guide for more details.
• Replication feature from Thales e-Security Key Authority KMIP server is not supported with
BES/FS8-18.
• In FOS 7.1.0 or later the encryption FPGA has been upgraded to include parity protection of lookup
memory (ROM) within the AES engine. This change enhances parity error detection capability of the
FPGA.
• BES/FS8-18 will reject the SCSI commands WRITE SAME, ATS(Compare and Write/Vendor Specific
opcode 0xF1) and EXTENDED COPY, which are related to VAAI (vStorage APIs for Array Integration)
hardware acceleration in vSphere 4.1/5.x. This will result in non-VAAI methods of data transfer for the
underlying arrays, and may affect the performance of VM related operations.
• VMware VMFS5 uses ATS commands with arrays that support ATS. BES/FS8-18 does not support this
command set. Use of a workaround procedure is required in order to configure encryption in a VMFS
5 environment. Please refer to Brocade Tech Note “Deployment Options for VMware VMFS-5 with
Brocade Encryption” for details.
• XIV storage arrays that have been upgraded to firmware 11.2x or later required to support encryption
on thin provisioned LUNs will report all XIV data LUNs as TP=Yes.
FCIP (Brocade 7800 and FX8-24)
• Any firmware activation will disrupt I/O traffic on FCIP links.
• Latency measurements supported on FCIP Tunnels:
o 1GbE & 10GbE - 200ms round trip time and 1% loss.
• After inserting a 4G SFP in GE ports of an FX8-24 blade or 7800 switch, sometimes “sfpshow”
output might display “Cannot read serial data!”. Removing and re-inserting the SFP should
resolve this issue. It is recommended that users perform sfpshow immediately after inserting
the SFP and ensure SFP is seated properly before connecting the cables.
• When running FOS v7.2.0 or later, if the new FCIP Circuit Group feature is configured on any
FCIP Circuits, a downgrade operation to pre-FOS v7.2.0 will be blocked until the feature is
removed from the FCIP configuration(s).
FCIP (Brocade 7840)
• Brocade 7840 does not support FCIP connection to Brocade 7800 or FX8-24.
• FOS v7.3- does not support concurrent non-disruptive firmware download.
• FOS v7.3- does not support 10G speed on the 24 16G FC ports on Brocade 7840.
• FOS v7.3- does not support VEX port on Brocade 7840.
• FOS v7.3- does not support base switch on Brocade 7840.
• FOS v7.3- does not support credit recovery on BI ports on Brocade 7840.
• Running offline diagnostic tests results in FCIP tunnels down. Reboot the switch after offline
diagnostic tests to recover the tunnels.
• Brocade 7840 supports Brocade 10 Gbps Tunable DWDM 80KM SFP+ optical transceiver.
Following CLI command can be used to configure the transceiver usage in Brocade 7840.
