Brocade Silkworm 3800 and the Sun StorEdge 9900 Series
Two Gb/sec Full Duplex and Smaller Switch Size

Volume 48, Issue 4

The Brocade Silkworm 3800, a 16-port, auto-sensing 2 Gb/sec Fabric Switch, delivering the next generation of performance and functionality for SAN environments, is available for connectivity to the Sun StorEdgeTM 9900 Series. Based on Brocade's third generation ASIC technology, the SilkWorm 3800 incorporates Advanced Fabric Services that enhance integration and management of networked storage. This design results in a faster ROI, higher performance fabric, lower administration cost and the preservation of existing SAN investment.

The SilkWorm 3800 differs from the 2400/2800 with its 2 Gb/sec full duplex vs. 1 Gb/sec full duplex in the older switches. The switch size is smaller (1U vs. 2U), the 3800 has the Brocade third generation ASIC with FabOS 3.0 that provide several new features:

  • Trunking: link aggregation technology
  • Auto-sensing ports to negotiate between 1 Gbps and 2 Gbps products
  • Hardware enforced zoning: new zoning features
  • Advanced fabric watch: simplifying user administration

The SilkWorm 3800 has 1U standard rack mount and third-generation ASIC that enhances security. Through this technology, Brocade provides hardware enforced World Wide Name zoning. WEB TOOLs, an intuitive and easy-to-use interface, enables organizations to monitor and manage single Brocade SilkWorm Fibre Channel fabric switches and small Brocade SAN fabrics. Tasks can be performed by using a JavaTM technology-capable Web browser from standard laptops, desktop PCs or workstations from any location within the enterprise. For mission critical configurations, redundant switches are strongly recommended.

License keys are required for the following options:

  • Advanced Performance Monitoring
  • Advanced Zoning
  • Extended Fabrics
  • Fabric Watch
  • ISL Trunking
  • QuickLoop

The Brocade Silkworm 3800 provides seamless integration with existing Brocade Fabrics and offers 99.999 percent availability with Brocade Intelligent Fabric Services Architecture.

Hardware enforced zoning based on the World Wide Name (WWN):

  • Ensures data access is protected by hardware enforced zoning for secure sharing of storage devices between operating systems
  • Fabric-connected devices are arranged into logical groups over the physical configuration of the fabric
  • Hardware zoning can be configured by WWN, port ID or Arbitrated Loop-Physical Address (AL-PA)
  • When cables or devices are moved, the zoning rules automatically follow
  • Fabric-wide zoning eliminates the need for manual reconfiguration when just one switch is changed
  • WWN zoning provides the flexibility of soft zones plus the additional security of hardware enforced zoning

The operating environment is the SolarisTM Operating Environment (Solaris OE). The recommended service level is SunSpectrum GoldSM. Installation is not included in the purchase price.

The SilkWorm 3000 family will be compatible with older-generation Brocade switches (F, FL and E_port). These different switches can co-exist in the same fabric. The AC units and fans on the SilkWorm 3800 are fully redundant and have no single point of failure.

On a per-port basis, the SilkWorm 3800 is less expensive than comparable director products while providing similar levels of availability, similar performance and advanced manageability features.
