Restrictions When using Virtual Connect Direct-Attach Fibre Channel for HP 3PAR Storage systems, there are some restrictions and differences in VC functionality:  A VC SAN fabric may only contain uplink ports of either Fabric Attach or Direct Attach type. VC will isolate ports that do not match the specified fabric type. An isolated port will degrade the fabric state with all associated server profiles and VC Domain state.  A server profile migration of a profile assigned to a SAN-booted server between enclosures in the Multi- EnclsoureDomainis notsupported.  A server profile assigned to a SAN-booted server cannot be migrated between enclosures in the Multi-Enclsoure Domain.  When VC Domains are managed by Virtual Connect Enterprise Manager (VCEM), a server profile migration of a SAN- booted server between enclosures within the same Virtual Connect Domain Group (VCDG) or between VCDGs is not supported.  In a Direct-attach architecture,a VC FlexFabric module will not distribute server logins evenly across uplink ports.The features and functionality of server login-balancing and login-distribution do not apply in this case.  Servers connecting to a direct-attach VC SAN fabric will have access to all devices connected on the uplink ports of that fabric. If more than one connection exists from a VC FlexFabric module to the same 3PAR Storage array, each server will see as many paths to the storage logical unit number (LUN) as number of those connections.  A multi-path OS driver must be used to achieve failover to alternate paths and I/O load-balancing. 6
