When using out-of-band management with SMcli by
specifying the RAID Controller management port IP
addresses on the MD Storage Array, SMcli commands
that change the attributes of a virtual disk, virtual disk
copy, or snapshot virtual disk, must have management
access to the owning RAID Controller Module. Where
applicable it is best practice to specify both management
port IP addresses on the SMcli invocation: SMcli
192.168.128.101 192.168.128.102 -c.
On Linux systems Device Mapper multi-pathing drivers
are required for multi-path support
Virtual disks on MD Series Dense Storage Arrays cannot
be used for booting.
Disk Groups can be migrated between a Dell PowerVault
MD3260/3260i/3660i/3660f by following the appropriate
Disk Group migration procedure***
Disk pools cannot be migrated.
All iSCSI Host ports on a controller have to be at the
same port speed
iSCSI Host ports will only auto-negotiate to the port speed
set in MDSM
If the iSCSI initiators are connected to MD3260i and/or
MD3660i series through the network switches, make sure
that your switches support IEEE 802.3x flow control, and
the flow control is enabled for both sending and receiving
on all switch ports and server NIC ports.
If you do not enable the flow control, your iSCSI storage
array may experience the degradation of the I/O
performance.
In addition to enabling the Ethernet IEEE 802.3x flow
control it is also recommended to 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.
Please note that turning the "PortFast" mode on is
different from turning off the whole operation of STP on
the switch. With "PortFast" on, the STP is still enabled on
the switch ports. Do not turn STP off because it may
affect the entire network and can leave the network
vulnerable to physical topology loops.
To get the 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
should be connected to only one iSCSI target port on the
storage subsystem.
