6.4 Scalability enhancements made in v7.1 compared to v6.4
The following enhancements are made in v7.1, which enable IBM Flex System V7000
Storage Node to handle larger configurations with more hosts using more volumes with more
virtual machines:
򐂰 Increased number of hosts per I/O group from 256 to 512, and for a cluster, the previous
limit has been changed from 1024 to 2048 per cluster. This increase in number of hosts
can be used for any host type subject to limit restrictions for that host type.
򐂰 Increased number of volumes or LUNs per host from 512 to 2048. This increase is
applicable to any host type subject to host limitations. This increase is applicable also to
FC and FCoE host attachment types (subject to host limitations), but not for iSCSI.
򐂰 Increased number of host WWPNS per I/O group from 512 to 2048 and per cluster from
2048 to 8192. This increase applies equally to native FC and FCoE WWPNs and is a
fourfold increase between SVC 6.4.1 and 7.1.x.
