(a)
A group can contain a maximum of two PS4000, PS4100, and/or PS-M4110 arrays.
(b) Includes groups of mixed array types and all other group types except groups containing only PS40x0, PS41x0, and
PS-M4110 arrays. When a group contains a mix of PS40x0, PS41x0, and PS-M4110 arrays and other array models,
the higher limits prevail.
(c) Practical maximum volume size is operating system-specific. A PS Series group can create and present volumes up
to 15 TB.
(d) Up to 16 simultaneous replication operations can take place.
(e) To avoid service outages or possible loss of connectivity during failovers, Dell recommends increasing initiator
timeouts for groups with more than 512 connections. See the iSCSI Initiator and Operating Systems Considerations
document for more information.
(f) Inbound replication connections count towards the total number of connections.
(g) With firmware version 5.1, maximum number of volumes per group and maximum number of connections per pool
increased from 256 to 512
(h) Up to 1024 connections per pool are supported for all groups except groups containing only PS40x0, PS41x0, and
PS-M4110 arrays. This provides increased scalability in virtualized environments. These connections may be
distributed across a maximum of 512 volumes.
(i) Volumes automatically created and managed by the NAS Service inside the NAS Reserve pool used by an FS Series
appliance are fully allocated at creation and cannot be thin provisioned. Once those volumes are created (when
the NAS Reserve is created they cannot be shrunk.
