4 H-series switches and fabric rules This chapter describes the fabric rules for the HP StorageWorks H-series switches. It describes the following topics: • H-series switches, page 83 • Fabric rules, page 86 H-series switches The SN6000 Fibre Channel Switches: • Can be used as core or edge switches. When configured in a core-edge fabric topology, a core switch typically connects to other switches in the SAN; an edge switch typically connects to servers and storage. • Support multi-switch networks with up to 30 switches and 7 hops. • Have twenty 8 Gb ports and four stacking (high speed ISL) 10Gb ports. You can upgrade the10 Gb ports to 20 Gb. Using the 10 Gb/20 Gb ports for ISLs reduces or eliminates the need to use 8 Gb device ports for ISLs, allowing more device connections to the switch. • Can make use of the 10 Gb/20 Gb stacking ports to configure up to six switches into a stack (single manageable unit), resulting in up to 120 usable device ports in a stack. • Support plug-and-play compatibility. • Have two hot-swappable power supplies or one replaceable power supply depending on model. The 8/20q Fibre Channel Switches: • Can be used as core or edge switches. When configured in a core-edge fabric topology, a core switch typically connects to other switches in the SAN; an edge switch typically connects to servers and storage. • Support multi-switch networks with up to 30 switches and 7 hops. • Have 8 or 16 base ports, which you can upgrade to 20 ports in 4-port increments. • Support plug-and-play compatibility. The 8 Gb Simple SAN Connection Kit offers: • Ease of use • Cost efficiency The kit includes: • An 8/20q Fibre Channel Switch (8 base ports that can be upgraded to 12, 16, or 20), • (4) 81Q PCI-e FC HBAs • (10) 8-Gb SFP+ transceivers (SFP+ is the expanded standard for 8-Gb Fibre Channel support.) • (6) Fiber optic cables • Scalability You can expand the SAN in four port increments using license keys and additional HBAs and switches.
