Supersedes Fabric OS 6.4.1b, released March 2011 New features This section describes further details on the new features introduced with Fabric OS 7.0.0a. See the Fabric OS Administrator's Guide for 7.0.0 for further details on the features in this release. In-flight Encryption and Compression on 16 Gbps capable ISLs The in-flight encryption/decryption and compression/decompression features allow frames to be encrypted or compressed while traversing 16 Gbps capable ISLs. In-flight encryption provides security for frames while they are passing between two switches. Compression improves bandwidth utilization on the ISLs, especially over long distance. Encryption and compression are both disabled by default but may be enabled at an individual port level. A maximum of 4 ports at a time on each of the HP SN8000B 16 Gbps 32-port and 48-port Fibre Channel Blades can support encryption and compression. Encryption and compression can be enabled simultaneously on an ISL, or either encryption or compression alone can be enabled. There is no additional license required to use the in-flight encryption or compression capabilities. NOTE: This feature is enabled by the ASIC used on 16 Gbps FC platforms and it is independent of the speed at which the ISL is currently operating. Buffer Credit Loss Detection and Automatic Recovery on 16 Gbps capable ISLs Fabric OS 7.0.0a adds support for the detection and automatic recovery of buffer credits on 16 Gbps capable ISLs (both ends of the link must terminate on 16 Gbps capable ports). Loss of a single buffer credit is detected at individual Virtual Channel level and is automatically recovered without performing link reset. Loss of multiple buffer credits and stuck VC (VC in permanent zero buffer credit condition) conditions are recovered by performing link reset. RASlogs are generated when credit loss is detected and when the link reset is performed. 10 Gbps FC Capability on 16 Gbps FC Platforms Ports on the HP SN8000B 16 Gbps 32-port or 48-port Fibre Channel Blades for the HP SN8000B 8-Slot SAN Backbone Director Switch and the HP SN8000B 4-Slot SAN Director Switch can be configured to operate at 10 Gbps FC. This feature requires a 10 Gbps FC slot based license on the HP SN8000B 8-Slot SAN Backbone Director Switch or the HP SN8000B 4-Slot SAN Director Switch (for each blade that will have 10 Gbps FC ports). In Fabric OS 7.0.0a, this feature is supported only on the first eight ports of each HP SN8000B 16 Gbps blades. 6

Fabric OS 6.4.1b, released March 2011
New features
This section describes further details on the new features introduced with Fabric OS 7.0.0a. See the
Fabric OS Administrator's Guide for 7.0.0
for further details on the features in this release.
In-flight Encryption and Compression on 16 Gbps capable ISLs
The in-flight encryption/decryption and compression/decompression features allow frames to be
encrypted or compressed while traversing 16 Gbps capable ISLs. In-flight encryption provides security
for frames while they are passing between two switches. Compression improves bandwidth utilization
on the ISLs, especially over long distance. Encryption and compression are both disabled by default
but may be enabled at an individual port level. A maximum of 4 ports at a time on each of the HP
SN8000B 16 Gbps 32-port and 48-port Fibre Channel Blades can support encryption and
compression. Encryption and compression can be enabled simultaneously on an ISL, or either encryption
or compression alone can be enabled. There is no additional license required to use the in-flight
encryption or compression capabilities.
NOTE:
This feature is enabled by the ASIC used on 16 Gbps FC platforms and it is independent of the speed at
which the ISL is currently operating.
Buffer Credit Loss Detection and Automatic Recovery on 16 Gbps capable ISLs
Fabric OS 7.0.0a adds support for the detection and automatic recovery of buffer credits on 16 Gbps
capable ISLs (both ends of the link must terminate on 16 Gbps capable ports). Loss of a single buffer
credit is detected at individual Virtual Channel level and is automatically recovered without performing
link reset. Loss of multiple buffer credits and stuck VC (VC in permanent zero buffer credit condition)
conditions are recovered by performing link reset. RASlogs are generated when credit loss is detected
and when the link reset is performed.
10 Gbps FC Capability on 16 Gbps FC Platforms
Ports on the HP SN8000B 16 Gbps 32-port or 48-port Fibre Channel Blades for the HP SN8000B
8-Slot SAN Backbone Director Switch and the HP SN8000B 4-Slot SAN Director Switch can be
configured to operate at 10 Gbps FC. This feature requires a 10 Gbps FC slot based license on the
HP SN8000B 8-Slot SAN Backbone Director Switch or the HP SN8000B 4-Slot SAN Director Switch
(for each blade that will have 10 Gbps FC ports). In Fabric OS 7.0.0a, this feature is supported only
on the first eight ports of each HP SN8000B 16 Gbps blades.
