See "Part III, Host and storage systems rules" of the HP SAN Design Reference Guide and the Quickspecs for HP P6000 Continuous Access and the applicable array model. • • • • Maximum number of single-member DR groups per array7 128 128 256 128 (4400) 128 (4400) 128 (4400) 256 (64/8400) 256 (64/8400) 256 (64/8400) Maximum number of virtual disk members of all DR groups per array7 128 128 256 128 (4400) 128 (4400) 128 (4400) 256 (64/8400) 256 (64/8400) 256 (64/8400) Maximum number of virtual disk members per DR group 8 32 32 32 32 32 Maximum combined capacity (in TB) of a DR group's virtual disk members and those members' snapshots, snapclones, or 16 16 32 80 80 80 mirrorclones Preferred path • • • • Replication relationships 2:1 2:1 4:1 4:18 4:18 4:18 Set access to no-read on remote copy • • • • • Set disk group for log disk (at creation) • • • • • Set host port priority for replication • • • • Set maximum log disk size (at creation) • • • • • Set Vraid on remote copy (at creation) • • • • • Source and destination pair size 1 GB to 2 TB (in 1 GB increments) Suspend on failover (set at creation) • • • • • Switches per fabric9 See "Part II, Fabric infrastructure rules" of the HP SAN Design Reference Guide . 6In XCS versions 6.2xx and 09501x000 or later, the instant restore of the source DR group member results in a Fast Copy of the new data, not a Full Copy. 7For best performance when using HP P6000 Replication Solutions Manager, do not exceed 512 single-member DR groups and 512 source-destination pairs across all arrays. Other limits may apply. 84:1 is only supported when the source of the FAN-out or the target of the FAN-in is a high-end array, which is an array with 4 host ports per controller or 8 host ports per array. Any HP P6000 Continuous Access-supported array can be the target of the FAN-out or the source of the FAN-in. 9The switch restrictions that previously applied to XCS 09003000 have been removed. See Table 7.0, EVA host connectivity, for details on how to locate switch support information. 36
