The HP StorageWorks 4/8 Base SAN Switch and 4/8 SAN Switch offer 4 GB connectivity for entry-level storage area networks (SAN), and the ability to grow to a core-to-edge infrastructure. The simplicity and ease-of-use advantages of these switches help increase administrator productivity and lower the cost of management. Both switches deliver eight (upgradeable to16) high performance Auto Sensing 1, 2, and 4GB/s Fibre Channel ports. An optional 4 port activation license increases the number of active ports to 12 or 16 ports. Plus, the 4/8 SAN switch and 4/8 SAN Switch are fully non-blocking and provide 64 to 128 Gb switching (4Gb full duplex) bandwidth. The 4/8 Base model provides single-switch connectivity for a new, simple SAN installation and connects to storage and servers only. The 4/8 SAN Switch scales to full SAN configurations defined in the SAN Design Guide. Small-form-factor-pluggable optical transceivers (SFPs) must be ordered separately.
