SANs with Ethernet and IP: iSCSI.

IT managers now have a choice when considering SAN management options. The QLA4050, QLA4050C, and QLA4052C (collectively referred to as the QLA405x) iSCSI HBAs provide connectivity to SANs over Ethernet and TCP/IP network infrastructures (switches, routers, and VPN appliances). Using a widely deployed and familiar networking technology, iSCSI can lower the total cost of ownership to better manage and support storage networking.

Features and Benefits
  • Networking and storage functionality for iSCSI, network attached storage (NAS), clustering, multimedia, distributed network applications, and web-serving
  • Jumbo frames, 802.3x flow control, 802.1p priority service, and 802.1Q VLAN Ethernet networking
  • Storage reliability with iSCSI digests, ECC memory, and overlapping data path parity
  • SANsurfer® storage area network (SAN) device management application and drivers for all major operating systems
  • Microsoft Windows® management interface (MS WMI), Storage Networking Industry Association (SNIA) iSCSI management application programming interface (IMA), and storage management interface specification (SMI-S) compliant for standards based management
  • Low-profile PCI form factor (Low profile and standard PCI bracket included)
  • Universal iSCSI SAN boot for true remote storage boot implementations
  • Complete iSCSI and TCP/IP offload for enhanced performance
  • Auto-negotiated 100/1000 Mbps line rate data transfer
  • PCI-X 133-MHz backward-compatible with 32/64-bit, 33/66-MHz PCI
