a. A group can contain a maximum of two PS4000, PS4100, PS4110, PS4210, and/or PS-M4110
arrays.
b. Includes groups of mixed array types and all other group types except groups containing only
PS40x0, PS41x0, PS42x0, and PS-M4110 arrays. When a group contains a mix of PS40x0,
PS41x0, PS42x0, 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 EMC 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, PS42x0, 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).
j. This value includes vVols, vVol snapshots, and vVol-lined clones.
k. When mixing PS6XXX and PS4XXX arrays, SyncRep remains at 4 volumes if any PS4XXX
members are in the group.
l. SCSI fencing is not supported for Red Hat

Enterprise Linux

. See the iSCSI Initiator and
Operating System Considerations document for more information.
m. This value includes one local and one root CA certificate; the rest are intermediate CA
certificates.
