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 N/A same port speed iSCSI Host ports will only auto-negotiate to the port speed N/A set in MDSM If the iSCSI initiators are connected to MD3260i and/or N/A 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 N/A 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. √ For convenience, regarding Dell Oracle Tested and Validated solutions involving MD arrays, please refer to the following site < http://en.community.dell.com/techcenter/enterprise- solutions/w/oracle_solutions/current-release.aspx > The number of VD copies is limited to a √ - maximum of 511 with a maximum of 8 concurrent copies √ √ √ √ √ √ √ √ √ √ Only √ 1Gbps Supported Only √ 1Gbps Supported √ √ √ √ √ √ √ √ √ √ √ √ N/A N/A N/A N/A √ √ Applicable to firmware version 07.84.xx.xx 3
