HP StorageWorks Fabric OS 5.2.1b Release Notes (AA-RWEYC-TE, June 2007)

Management
• Role-Based Acc
ess Control (RBAC) adds sup port for the new RBAC roles: Operator, Zone
Manager, Fabric Administrator, and Basic Switch Administrator.
• Virtual fabrics through administrative domains (Adm in Domains or AD) provides data,
management, and fault isolation through administrative domains.
• DHCP support f
or B-Series switches.
Security
• Device Connection Control (DCC) and Switch Conn ection Control (SCC) provide the ability to
manually distribute passwords among participating switches in the base Fabric OS.
• Internet Protocol Security (IPSec) ensures private, secure communications over Internet Protocol (I P )
networks to prevent network-based attacks, which could potentially result in denial of ser vice,
data corruption, data theft, user cred ential theft, and so on. The IPSec license is available as an
option bundled with the HP StorageWorks FCIP, IPSec license.
Fibre Channel Routing (FCR) enhancements
FCR enhancements for the 400 MP Router and B -Series Router blade in the 4/256 SAN Director include:
• Front domain consolidation, which provides one front domain per chassis projected to edge
fabrics, regardless of the number of EX_ports connected from the FR4–18i blade to the edge
fabric in the 4/256 Director.
• McDATA in
teroperability in Open Fabric modes.
• EX_port trunking, which provides high bandwidth across the router.
• Router port cost providing users flexibility to determine the preferred route between two
destina
tions across a m eta SAN.
Fibre Channel over I P (FCIP) enhancements
• Internet Protocol Security (IPSec); see the description provided above.
• FastWrite reduces the number of round trips required to comp lete a SCSI Write I/O, which both
reduces I/O completion latency and increases FCIP ISL bandwidth utilization.
• Tape Pipelining accelerates SCSI Write I/Os between geographically remote initiators and tape
devicesonFibreChannelSANslinkedviaFCIPISLs.
• WAN tool; the ipper f option has been added to the portCmd command to characterize
end-to-end IP pa th performance factors, such as bandwidth, loss rate, round-trip time, and path
Maximum Transmission Unit (MTU) between a pair of FCIP ports.
New fe
atures FC4–16IP (iSCSI blade)
The FC4-16IP iSCSI blade enables the HP StorageWorks SAN Director 256 to provide iSCSI initiators
to FC target connectivity. Please see the Application Notes for the HP StorageW orks B-Series iSCSI
Director Blade for more information.
Dynamic Host Configuration Protocol (DHCP) support for embedded switches
Beginning with Fabric OS 5.2.1b firmware, DHCP is now supported on the following embedded switches:
• Brocade 4Gb SAN Switch for HP p-Class BladeSystem
• Brocade 4Gb SAN Switch for HP c-Class BladeSystem
With SAN switch for HP c-Class BladeSystems, DHCP is enabled by default on rev C or later. The status
of DH CP (enabled or disabled) can be observed and changed via either Web Tools or CLI.
