Dell EMC PowerVault MD Series storage array

rules

This section contains both general and model-specic connectivity and consideration rules for Dell EMC PowerVault MD storage arrays.

The rules listed in Table 2 apply to all storage array models. For rules applying to specic Dell EMC PowerVault MD models, see Table 3 and

Table 4.

NOTE: Dell EMC PowerVault MD3460, MD3860i, and MD3860f platforms are supported in dual-RAID controller (duplex)

congurations only.

SAS HBA cards for all redundant cabling congurations.)

A hot-spare for a disk group must be a physical disk drive of equal or greater

size than any of the member disks.

Yes Yes Yes

When using out-of-band management with SMcli by specifying the RAID

controller management port IP addresses on the Dell PowerVault 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 a best practice to

specify both management port IP addresses on the SMcli invocation:

• SMcli 192.168.129.101 192.168.129.102 –c (2U Array)

• SMcli 192.168.128.101 192.168.128.102 –c (4U Dense Array)

Yes Yes Yes

On Linux systems, Device Mapper multipath drivers are required for

multipath support.

Yes Yes Yes

Coexistence of several Linux multi-path drivers is not supported. When using

a Dell PowerVault MD3400 or MD3800 series array with Linux host servers,

only the Linux Device Mapper failover driver is supported.**

Yes Yes Yes

Virtual disks on Dell PowerVault MD Series Storage Arrays cannot be used

for booting.

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

3860f by following the appropriate disk group migration procedure.***

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 dierent 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 aect

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.

N/A Yes N/A

For Dell-Oracle Tested and Validated solutions on the Dell PowerVault MD

arrays, refer to the following site https://www.dell.com/support/

Yes Yes Yes

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

Maximum number of iSCSI sessions N/A 512 per port N/A

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.

Replication within FC topology between MD36x0f or MD38x0f arrays is

supported regardless of connection speed. Replication between iSCSI and

FC topology is not supported.

N/A N/A Yes

Online Physical Disk Firmware Upgrade is supported. Yes Yes Yes

When using physical disks of 6 TB or larger capacity, it is recommended to

use either a RAID 6 Disk Group or a Dynamic Disk Pool (DDP). Due to the

increased amount of time taken to reconstruct and copy-back, the chances

for a second drive failure increases on either a RAID 1/10 or a RAID 5 Disk

Group.

Yes Yes Yes

Data Assurance capable drives are supported in the array, however the Data

Assurance feature is not an available option for these arrays.

Yes Yes Yes

Support for up to 192 physical disk drive slots using a premium feature

option.

Up to 15 MD1200 and/or MD1220 series expansion enclosures can be

attached to a Dell PowerVault MD storage array. Any mixture of MD1200

and MD1220 enclosures for a total of 192 physical slots is supported.
