HP StorageWorks 2/32 HP StorageWorks Fabric OS 5.2.1b Release Notes (AA-RWEYC- - Page 6

Management • Role-Based Access Control (RBAC) adds support for the new RBAC roles: Operator, Zone Manager, Fabric Administrator, and Basic Switch Administrator. • Virtual fabrics through administrative domains (Admin Domains or AD) provides data, management, and fault isolation through administrative domains. • DHCP support for B-Series switches. Security • Device Connection Control (DCC) and Switch Connection 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 (IP) networks to prevent network-based attacks, which could potentially result in denial of service, data corruption, data theft, user credential 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 interoperability 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 destinations across a metaSAN. Fibre Channel over IP (FCIP) enhancements • Internet Protocol Security (IPSec); see the description provided above. • FastWrite reduces the number of round trips required to complete 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 devices on Fibre Channel SANs linked via FCIP ISLs. • WAN tool; the ipperf option has been added to the portCmd command to characterize end-to-end IP path performance factors, such as bandwidth, loss rate, round-trip time, and path Maximum Transmission Unit (MTU) between a pair of FCIP ports. New features 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 StorageWorks 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 DHCP (enabled or disabled) can be observed and changed via either Web Tools or CLI. 6
