Brocade to ship 64-port 'integrated fabric'
Partly in response to competition from 32-port and 64-port director-class switches, Brocade has announced a 64-port integrated switch configuration. The SilkWorm 6400, due in March, combines six 16-port Fibre Channel switches, for a total of 64 usable ports (the extra 32 ports are used for inter-switch links).
In contrast, Fibre Channel directors provide 32 or 64 ports in one switch. Directors are available from vendors such as Inrange, McData, and QLogic. But Brocade claims its configuration is about half the price of directors. The SilkWorm 6400 costs $150,000, or $2,344 per usable port. Jay Kidd, vice president of marketing, says Brocade will eventually offer 64-port and 128-port director-class switches, called "core fabric switches," but the company has not committed to a delivery time frame. (A formal announcement is expected within the next couple of months.)
The SilkWorm 6400 comes in a 14U enclosure and includes hardware-based zoning, which allows administrators to isolate groups of servers and storage devices.
On the software front, Brocade introduced Fabric Manager, an application that provides a centralized view of the 6400 switch, and Fabric Watch software for SAN monitoring via SNMP. A QuickLoop feature allows the connection of Fibre Channel arbitrated-loop devices to the 6400. The switches ship with Brocade's Fabric Operating Systems code. www.brocade.com.

LSC, Tivoli enable 'true' file sharing
LSC Inc. announced it has developed application programming interfaces (APIs) that enable its QFS and SAM-FS file-system and management software to work with Tivoli SANergy 2.2 for high-performance file sharing in heterogeneous storage area networks (SANs).
While other programs have tried to accomplish heterogeneous file sharing in SANs, Tivoli points to inefficiencies with the meta data controller in the Unix UFS (Universal File System) as gating factors, which may be responsible for up to a 50% reduction in SAN performance.
The file-management structure of SAM-FS and QFS avoids these inefficiencies, creating a high-performance file-management software setup for heterogeneous SANs, company officials claim.
LSC is the first vendor to be certified Tivoli Ready for SANergy, and is the first company to take advantage of the new APIs in SANergy 2.2.
With SANergy, QFS and SAM-FS can also operate with MacOS, Irix, AIX, Tru64, DG/UX, Windows NT/2000, Solaris, and Red Hat Linux.
Tivoli incorporates T11
Separately, at Storage Network World, Tivoli unveiled its Storage Network Manager software, which incorporates the recently defined ANSI T11 SAN discovery and management standards. Storage Network Manager enables users to manage heterogeneous SANs across several platforms using hardware and software from various vendors. (For more information, see InfoStor, November 2000, p. 1.)
The ANSI FC-MI (Fibre Channel Methodologies for Interconnects) ensures interoperability and standardized discovery and management when implementing Fibre Channel networks. The FC-MI profile was created by Agilent, Brocade, Compaq, Cross-roads, EMC, Emulex, Gadzoox, Hewlett-Packard, IBM, LSI, McData, Pathlight, JNI, QLogic, Seagate, Sun Microsystems, StorageTek, Tivoli, and Troika. www.tivoli.com.
