  • Page 2: Abstract

    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 SANs using Fibre Channel (FC) interconnect technology.
  • Page 3 The HP BladeSystem c3000 enclosure (Figure 2) is similar in design and functionality to the c7000 enclosure but has a compact 6U chassis that can be installed in a rack or deployed as a stand-alone tower. The c3000 enclosure supports the same c-Class server blades and interconnects used in the c7000 enclosure.

    c-Class server FC interconnect options All c-Class server blades have expansion slots that accept optional mezzanine cards in support of several fabric options. Half-height server blades have two mezzanine slots; full-height blades have three slots (Figure 3). Figure 3.

    c-Class FC SAN interconnect modules The following FC options are available for connecting the c-Class FC HBAs to a SAN: • HP Virtual Connect 8Gb 24-Port Fibre Channel Module for BladeSystem • HP Virtual Connect 8Gb 20-Port Fibre Channel Module for BladeSystem •...
  • Page 6 HP Virtual Connect Fibre Channel Modules provide the highest levels of availability and reliability by ensuring that 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 profiles and can be deployed anywhere within a Virtual Connect domain.
  • Page 7: Port Mapping Of Server Blade Fc Hba Mezzanine Cards

    HP 4Gb Pass-Thru Module for the HP c-Class BladeSystem The HP 4Gb Pass-Thru Module provides transparent, 1:1 port connectivity (16 internal/16 external) between HBA mezzanine ports and external SAN devices or switches. The module, which has 16 ports with short-wave 4-Gb SFP transceivers, provides a solution for connecting c-Class FC HBAs to a local SAN.
  • Page 8 Figure 5 shows the mapping of the FC connectivity options for the c7000 enclosure. Figure 5 illustrates the maximum FC connection capability of the c7000 enclosure. In practice, server blades can support a mix of mezzanine cards of different interface types (FC, Ethernet, or InfiniBand) simultaneously within the enclosure.
  • Page 9 Figure 6 illustrates the mapping of FC connectivity options for the c3000 enclosure. Figure 6 illustrates the maximum FC connection capability of the c3000 enclosure. In practice, server blades can support a mix of mezzanine cards of different interface types (FC, Ethernet, or InfiniBand) simultaneously within the enclosure.
  • Page 10 HP BladeSystem c-Class enclosures include an HP Onboard Administrator. The Onboard Administrator provides run-time management and configuration of all components in the enclosure. When the system is booted, the Onboard Administrator of the enclosure checks the configuration of server blades and interconnect modules for errors. The system status, including interconnect data, appears on the HP Insight Display at the front of the enclosure.

  • Page 12: Port Redundancy Strategies

    The number of FC interconnect modules required for an HP 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: •...
  • Page 13: Selecting Interconnect Module Types

    Selecting interconnect module types The optimum type of interconnect module for use in a system will be determined by several factors such as SAN proximity, fabric size, number of server blades to be connected, and performance and availability goals. Pre-existing SAN attributes also affect the choice of interconnects. Connecting with pass-thru modules The HP 4Gb FC Pass-Thru Module provides a solution for connecting server blades to a SAN when the customer does not want to deploy Fibre Channel switches in the BladeSystem enclosure.
  • Page 14: Connecting With Hp Virtual Connect Fibre Channel Modules

    Connecting with HP Virtual Connect Fibre Channel modules HP Virtual Connect Fibre Channel (VC-FC) modules provide the ability to quickly assign SAN storage to a server. Virtual Connect also provides the ability to quickly migrate server SAN storage assignments from one server to another for easy reallocation of servers and storage resources. In the event that a server needs to be taken offline, Virtual Connect allows another server to quickly assume the identity of the original server such that the assigned SAN Storage is accessible by the replacement server.
