This white paper is primarily intended for those who are involved in defining, implementing, or supporting an EqualLogic storage network using the new EqualLogic PS-M4110 blade array as part of a strategy that deploys storage with the purpose of providing data for use by the blade servers located in the same Dell M1000e Blade Enclosure.
4 Reference architecture overview The Storage Interoperability Lab conducted preliminary testing on a self-contained M1000e based data center-in-a-box architecture that included testing of multiple networking components as well as using blade servers from the latest two generations of M-Series blade servers. The following sections describe the various sub-systems used: 4.1 PowerEdge M-Series blade servers The blade servers used servers from the last two generations of PowerEdge M-Series servers.
4.2 IO module information LAN IO modules were installed in Fabric Slots A1 and A2 for all tests. SAN IO modules were installed in Fabric Slots B1 and B2 for all tests (except for tests involving the Broadcom 57712k which is a Network Daughter Card (NDC) where Fabric A was used). The IO modules tested are listed in Table 2 below.

5 Switch configuration Any of the currently available 10Gb Ethernet IO modules can be used as SAN switches within this reference architecture. The following sections provide the detailed list of CLI commands used to configure each switch model for use as a SAN switch to support the PS-M4110 Storage Blades as defined in the reference architecture described in Section 4.
5.2 PowerConnect M8024-K 5.2.1 iSCSI Auto-Configuration The PowerConnect M8024-k IO module supports the “iSCSI Auto-configuration” feature. When enabled, the switches will automatically enable link level flow control on all ports of the switch and configure the switch for jumbo frames (mtu 9216). Monitoring for EqualLogic storage arrays via LLDP is also enabled by this command.
Spanning Tree is a global configuration setting for the PowerConnect M8024k. Spanning Tree is enabled by default on the PowerConnect M8024k. Rapid Spanning Tree (rstp) is the default mode for spanning tree for the PowerConnect M8024k. If the state of the spanning-tree settings is unknown, use the following commands to enable spanning tree: console>enable console#config...

6 General recommendations and guidelines • Recommend for use with general purpose small-medium sized consolidated loads. • Not recommended for purpose built heavy I/O applications. • Do not directly attach 10GbE arrays to 1GbE IOMs. • IOMs are just like any other switch and must follow the same configuration recommendations as other Top of Rack (ToR) switches.

A. Port Map This appendix contains the port mapping information for the IOMs used during testing. During testing of each M-Series IO Module, the blade servers and PS-M4110 blade arrays remained in the same server slots, resulting in an internal port mapping that was similar for all three IOMs. The Force10 MXL has 32 internal network connections and the per server slot connection map is illustrated in Figure 4 below.
