Abstract Storage Area Network (SAN) connectivity with HP BladeSystem c-Class server blades is distinctly different from SAN connectivity with other HP ProLiant servers. This paper describes the hardware and software required to connect BladeSystem c-Class server blades to SANs1 using Fibre Channel ( - HP BL460c | HP BladeSystem c-Class SAN connectivity technology brief - Page 3

between the driver and firmware and reduces the number of software components that administrators must mange. The Emulex and QLogic 4-Gb cards are compatible with all ProLiant c-Class and Integrity server blades.

-performance, auto-negotiating external SFP ports. The modules allow moving or replacing server blades efficiently without involving SAN administrators. Each module provides 16 internal ports for connections with server blade HBAs and four or eight external ports (depending on model) for connections - HP BL460c | HP BladeSystem c-Class SAN connectivity technology brief - Page 6
server connectivity within each module is fault tolerant. The HP Virtual Connect Ethernet Module (required when HP Virtual Connect FC Modules are used) can manage server . The Brocade 8-Gb SAN Switch is available in the following configurations: • The12-port model supports any combination of internal - HP BL460c | HP BladeSystem c-Class SAN connectivity technology brief - Page 7
fabric performance. • Virtual SAN (VSAN) support - Up to 16 VSANs per switch can be managed as independent fabrics for more efficiency and lower cost through shared use, and for increased security through isolation of devices on the same physical SAN.

The system status, including interconnect data, appears on the HP Insight Display at the front of the enclosure.

BladeSystem c7000 Enclosure is determined by the number of FC ports per server blade (Table 2). HP recommends the use of redundant SANs. Redundancy for FC HBA mezzanine cards requires the following configurations: • One or more server blades with a dual-port FC HBA card require two FC interconnect - HP BL460c | HP BladeSystem c-Class SAN connectivity technology brief - Page 13
number of the server blades in the enclosure will ever require a SAN connection. Each pass-thru module provides dedicated paths between up to 16 server blades and an equal number of SAN switch ports or SAN target 1-16 to server blades (devices 1-8, port 2) (devices 9-16, port 2)* HP pass-thru - HP BL460c | HP BladeSystem c-Class SAN connectivity technology brief - Page 14
