Disk Groups can be migrated between a Dell PowerVault MD3460/3860i/

Yes Yes Yes
Maximum size of a virtual disk in a dynamic disk pool: 64TB Yes Yes Yes
Disk pools cannot be migrated. Yes Yes Yes
Maximum capacity (disk space) for each array for dynamic disk pooling 1024 TB 1024 TB 1024 TB
Maximum SSD cache size allowed depends on the installed RAM per
controller:
• 4GB RAM per controller supports up to 4TB SSD read cache
• 8GB RAM per controller supports up to 5TB SSD read cache
Yes Yes Yes
All iSCSI host ports on a controller must have the same port speed. N/A Yes N/A
Maximum 12 Gbps SAS cable length supported is 6m. Yes Yes Yes
If the iSCSI initiators are connected to Dell PowerVault MD3800i series
through the network switches, make sure that your switches support IEEE
802.3x ow control, and the ow control is enabled for both sending and
receiving on all switch ports and server NIC ports.
If you do not enable the ow control, your iSCSI storage array may
experience the degradation of the I/O performance.
In addition to enabling the Ethernet IEEE 802.3x ow control, Dell
recommends that you disable unicast broadcast storm control on the switch
ports connected to the iSCSI initiators and target arrays and turn on the
"PortFast" mode of the spanning tree protocol (STP) on the switch ports
connected to the iSCSI initiators and target arrays.
NOTE: Turning on the "PortFast" mode is dierent from turning o
the whole operation of STP on the switch. With "PortFast" on,
STP is still enabled on the switch ports. Turning o STP may aect
the entire network and can leave the network vulnerable to
physical topology loops.
N/A Yes N/A
For optimal I/O performance, avoid having more than one iSCSI session
originating from one host iSCSI port to the same controller. Ideally, the iSCSI
host NIC must connect to only one iSCSI target port on the storage
subsystem.

The number of Virtual Disk (VD) copies is limited to a maximum of 511 with a
maximum of 8 concurrent copies (applicable to RAID controller rmware
version 08.10.05.60 or later).
Yes Yes Yes
Remote replication is not supported in simplex mode. N/A Yes Yes
For Fibre Channel and iSCSI controllers, if you use the SAS host ports, they
must be connected to a SAS HBA on a separate host.
N/A Yes Yes

Replication within iSCSI topology between MD32x0i, MD36x0i, or MD38x0i
arrays is supported regardless of connection speed. Replication between
iSCSI and FC topology is not supported.
