NETSCOUT Unveils First-to-Market Independent Performance Management for Virtual SANs

March 25, 2004

Monitoring and Reporting on Individual VSAN Partitions and Traffic; Efficient Troubleshooting and Lower TCO via New Fibre Channel Switch Roving

WESTFORD, Mass., March 25 /PRNewswire-FirstCall/ -- NetScout Systems, Inc. (Nasdaq: NTCT), a leading provider of enterprise-wide network performance management solutions, announced today that it is the first independent vendor to deliver performance monitoring and reporting for Virtual SAN (VSAN) technology. VSAN is a SAN partitioning technology available through the Cisco MDS 9000 Family of Multilayer Intelligent directors and fabric storage area networking (SAN) switches. In addition, NetScout expanded its Fibre Channel troubleshooting capabilities with new switch roving support. The new features are enabled by firmware enhancements to NetScout's nGenius(R) Fibre Channel Probes and software enhancements in nGenius Performance Manager 2.0.1.

Through VSANs, storage administrators can build more scalable and reliable SANs able to support multiple applications in a single physical infrastructure. Using NetScout's new VSAN monitoring capabilities, SAN managers can identify, analyze and trend the traffic being delivered for each VSAN for real-time troubleshooting and long-term capacity planning. In addition, they can understand the resource requirements of each VSAN and its contributions to overall interswitch link traffic. NetScout's ability to monitor and report on individual types of SAN activity complete the necessary visibility needed by a SAN manager to proactively optimize the SAN.

"We have introduced VSAN and Inter-VSAN routing features in the Cisco MDS 9000 in order to provide SAN managers with the means to better control and segment their storage traffic," said Bill Erdman, director of marketing in the Storage Technology Group at Cisco Systems. "The Cisco MDS 9000 also offers other innovative features such as switch port roving that help customers accelerate troubleshooting. By supporting these features within their nGenius Solution, NetScout is helping our mutual customers effectively address the growing challenges of deploying and managing large SAN infrastructures."

"NetScout continues to anticipate the needs of large enterprises by introducing performance management for important new technologies such as VSAN," said Nancy Marrone-Hurley, senior analyst with Enterprise Storage Group. "VSAN technology and diagnostics features as well as switch roving are two of the key features driving customers to choose Cisco solutions. By supporting these features, NetScout is providing a level of visibility into SANs that no other vendor can provide today."

The nGenius 9800 Fibre Channel Probe can be configured to automatically discover and monitor Virtual SANs present on Enhanced Inter-Switch Links (EISL) in Cisco Fibre Channel SAN implementations. All the network performance analysis details provided on Fibre Channel segments are now extended to the VSANs. SAN managers can identify, monitor and report protocol details for the link and its associated VSANs, incorporating Fibre Channel specific details such as:

    * Traffic statistics of symptoms that may cause performance degradation
      including Frame Busy and Rejects, Port Busy and Rejects, Zero Credit
      Events and Initializations.
    * New Fibre Channel traffic views that detail Fibre Channel Protocol
      (FCP), Extended Link Services (ELS) and Basic Link Services activity.
    * Detailed views of Upper Layer protocol session activity including SCSI
      Initiator to Target/LUN conversations for such exchanges as SCSI reads
      and writes in FCP or Login traffic for ELS.

The addition of switch roving capabilities in the nGenius Fibre Channel Probes offers a cost-effective way to troubleshoot Fibre Channel segments and switches. Connected to a mirror port on a switch, an nGenius Probe can rove to all ports in the switch, allowing SAN managers to troubleshoot under- or over-utilization on a port, identify bandwidth hogs on a port, or execute a packet capture on a port to perform in-depth decode analysis. This new feature makes switch troubleshooting more efficient and also lowers the TCO for enterprises seeking proactive performance management in their Fibre Channel environments.

"Many of our enterprise customers are suspecting that the growth and complexity in their Fibre Channel SANs are contributing to slow downs in application performance for their users," said Michael Szabados, senior vice president of product operations for NetScout Systems. "We are committed to supporting innovative features such as VSAN that are helping the SAN industry mature and embrace the best elements of other networking technologies, so that true enterprise-wide network and application performance management can be achieved in a cost-effective manner."

The new enhancements are available in nGenius Performance Manager 2.0.1 Service Pack 1 and nGenius Probe Firmware CDM 2.1 for nGenius 9800 Fibre Channel Probes at no additional charge.
