3. MD3000i Introduction The Dell™ PowerVault™ MD3000i storage solution can enable either a standard or high
availability configuration. The standard model has a single controller with two 1GbE iSCSI ports.
It can be deployed to support up to 16 hosts non-redundantly. The high availability model has
dual controllers with two 1GbE iSCSI per controller for a total of four 1GbE ports. The dual
controller option can connect up to 16 fully redundant hosts. Each MD3000i controller also
contains an Ethernet port (not an iSCSI port) for out-of-band management.
Provisioning of storage on servers in a VM environment is a multiple step process starting with
definition of the server names for host access. The iSCSI connection is then established from the
storage subsystem, and after detection and configuration is established as a two way link with the
associated ESX server(s), completing the iSCSI communication subsystem. The final step
allocates the detected storage to the individual virtual machines (VM’s), where all or part of the
configured storage can be assigned to individual VM’s.
Note: NIC teaming is supported by the MD3000i only with VMware ESX/ESXi 3.5. The
MD3000i does not support NIC teaming with other operating systems.
Note: All NICs in a vSwitch must be in the same broadcast domain. If you connect the NICs
directly to the MD3000i, they will not be accessible on a broadcast.
4. MD3000i Reference Solution The following configurations illustrate recommended deployment for the MD3000i with ESX.
4.1 Up to 16 SAN-Configured Servers, Redundant Data Path, Dual Controllers (Duplex)
In this configuration, up to 16 VMware ESX servers are connected to the MD3000i via two
dedicated Ethernet switches. On each server, a Virtual NIC Team is created with one NIC
connected to Ethernet switch 1 and a second NIC is connected to Ethernet switch 2. Controller
ports 0-0 and 1-0 are connected Ethernet switch1, while controller ports 0-1 and 1-1 are
connected Ethernet switch2. A third NIC, not a member of the team, is connected to a
management network with one link from the management network going into each controller’s
management port. Up to two additional MD1000 enclosures can be daisy-chained to the
MD3000i.

Dell Inc Page 8 6. MD3000i Storage Setup and Configuration After opening the Modular Disk Storage Manager and selecting the MD3000i storage array to
be configured, select the Configure tab.
NOTE: in the examples to follow the Storage array “sg23_training” is an MD3000i with
virtual disks already configured using the Create Virtual Disks selection. The new server
being added to an existing host group is named “Valhalla”.
Host Group configuration starts from the following screen titled “Configure Host Access (Manual)
– Specify Host Group”. For ESX servers supporting VMotion, HA, and DRS, a host group must be
defined so the MD3000i storage subsystem has a configured iSCSI path to each of the hosts.
•
•
•
Select “Yes: This host will share access to the same virtual disks with other hosts”
If a new host group is desired select the radio button for that option and enter in a name
for your host group using standard host naming conventions (e.g. no spaces etc).
Should you already have one or more host groups assigned, select the radio button
enabling selection from a drop down list of existing host groups. This option is to be
used when configuring the second, third, etc. host in a group. Once the host group is
selected previously configured hosts for that host group will be displayed.
NOTE: These are shown as Linux hosts even though they are configured as ESX servers.
Selecting Next provides a Confirmation screen in which the new server being configured is shown
and the other previously configured associated hosts are named. For the first server configured
in a new host group there will be no associated hosts listed under the Associated host group.
From the Configure tab
1. Select Configure Host Access (Manual).
2. Enter the host name for the server which has the ESX Server software is installed.
3. Select Linux as the host type.
Figure 9: Configure Host Access – Specify Host Name and Host Type
Dell Inc Page 9 Note: If you are using MD3000i controller firmware that is earlier than Dell Version A02 version
06.70.15.60, then you are limited to 31 characters for the iSCSI alias. ESX generates the iSCSI
alias from the FQDN of the ESX server. As best practice, always update to the latest A-rev
firmware. If you are using A02 or later firmware, you will not have the 31 character limitation.
To find your controller firmware version, click on the support tab in MDSM. Then, click on View
Storage Array Profile. On the Summary tab, scroll down until you find firmware version.
4. Click on your iSCSI initiator and click Add to place into Selected iSCSI initiators.

Dell Inc Page 13 8. NX1950 Introduction Dell™ PowerVault™ NX1950 is a unified network storage solution that simultaneously stores
both file and application data while supporting a wide range of operating environments and
communication protocols, including the iSCSI standard. The PowerVault NX1950 can be
deployed as an integrated solution (Basic and High Availability configuration) packaged with a
Dell PowerVault MD3000 Storage Array or as a Gateway connecting directly to existing Dell|EMC
SAN. However, ESX only supports a subset of the available solutions for the PowerVault
NX1950.
This document provides instructions to setup an NX1950 Integrated Basic Configuration to
provide iSCSI storage for usage with VMware ESX Server software. The PowerVault NX1950
integrated basic storage solution consists of single-node configuration running Microsoft®
Windows® Unified Data Storage Server (WUDSS) 2003 operating system and is pre-configured
from Dell with a PowerVault MD3000 Storage Array.
Note: The Dell PowerVault NX1950 is supported only in integrated basic configuration with
VMware ESX using only the iSCSI protocol and not NFS. NX1950 is not supported in
Integrated High Availability configuration with VMware ESX.
The Microsoft iSCSI software target functionality included as part of WUDSS uses the Windows
TCP/IP network stack on NX1950 to provide block storage services to ESX server. The Microsoft
iSCSI software target creates storage devices as iSCSI virtual disks, which are files in the virtual
hard disk (VHD) format. These iSCSI virtual disks are assigned to specific iSCSI targets. Only the
iSCSI virtual disks assigned to an iSCSI target (exported to the iSCSI target) are available to the
iSCSI initiator running as part of VMware ESX server or inside a virtual machine. This storage
can be used by ESX server to create VMFS datastores or used directly by virtual machines as
block storage. This section covers NX1950 deployment instructions using the iSCSI initiator
within VMware ESX/ESXi. For instructions on using an iSCSI initiator inside a virtual machine,
refer to your specific initiator and guest operating system documentation.
9. NX1950 Reference Solution The following figure illustrates a typical setup for using NX1950 in an ESX Server farm. As a best
practice, Dell recommends using dedicated Gigabit Ethernet network to handle iSCSI storage
traffic.
Note: The Dell PowerVault NX1950 is supported only in integrated basic configuration with
VMware ESX using only the iSCSI protocol and not NFS. NX1950 is not supported in Integrated
High Availability configuration with VMware ESX.
