Supersedes
Fabric OS 7.0.0b, released September 2011
New features
This section describes further details on the new features introduced with Fabric OS 7.0.0x. See
the Fabric OS Administrator's Guide for Fabric OS 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 2 ports at a time on the
HP SN6000B 16Gb FC Switch and maximum of 4 ports at a time on each of the HP SN8000B
16Gb 32-port and 48-port FC 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 7.0.0x 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 SN6000B 16Gb FC Switch or on the HP SN8000B 16Gb 32-port or 48-port FC
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 and 10
