When using two blades, the initiator is registered in both blades for consistency, whether or not you intend to access both blades. Number of paths required per initiator After establishing the number of initiators, determine how many paths are required by each. The number of connections per blade is finite, and every initiator login constitutes a connection to the MPX200. In a multipath environment, HP recommends a minimum of one connection per blade; high-performance applications may require up to four connections per blade (a total of eight). Use of iSNS The MPX200 presents one iSCSI target for each virtual port group (VPG) (a total of four). Each initiator, therefore, discovers four times the number of FC targets. HP recommends that you use iSNS to present to the initiator only the required iSCSI targets. Use of iSCSI ports When configuring the MPX200 for iSCSI, there are four available iSCSI ports per blade. For high performance and maximum initiator connectivity, HP recommends that you use all available ports. Balancing the load HP recommends that you use all iSCSI ports for both 1-GbE and 10-GbE blades. If multiple 1-GbE initiators are required, ensure that logins are spread across all 1-GbE ports. For 10-GbE blades, you can place a higher number of initiators on the 10-GbE ports than on the 1-GbE ports. MPX200 Multifunction Router User Guide 25
