nodes. As stated in 2.4.1, “Control canister” on page 48, each canister on the IBM Flex
System V7000 Storage Node has host attachments on one control canister which match the
configuration of the second canister and must use the same slots. The Network Adapter slots
correspond to the following I/O module slots on the IBM Flex System Enterprise Chassis:
򐂰 Network Adapter slot 1 in each node canister connects to IO modules 1 and 2
򐂰 Network Adapter slot 2 in each node canister connects to IO modules 3 and 4
Network Adapter cards must be installed in pairs (one card per node canister) and the
following configurations are supported:
򐂰 Two or four 10Gb CNA cards
򐂰 Two 8Gb FC cards
򐂰 Two 10Gb CNA cards and two 8Gb FC cards
Adapters Supported on IBM Flex System V7000 Storage Node include:
򐂰 IBM Flex System EN2024 4-port 1Gb Ethernet Adapter
򐂰 IBM Flex System EN4054 4-port 10Gb Ethernet Adapter
򐂰 IBM Flex System FC3172 2-port 8Gb FC Adapter
򐂰 IBM Flex System FC5022 2-port 16Gb FC Adapter
򐂰 IBM Flex System FC3052 2-port 8Gb FC Adapter (Emulex)
򐂰 IBM Flex System CN4054 10Gb Virtual Fabric Adapter
򐂰 IBM Flex System CN4058 8-port 10Gb Converged Adapter
The Network Adapter on IBM Flex System V7000 Control Enclosure canister will
communicate to switch modules on the IBM Flex System Enterprise Chassis I/O module
ports. Some pass-through modules are available as an alternative to switches on the IBM
Flex System Enterprise Chassis I/O modules. I/O Modules supported on IBM Flex System
V7000 Storage Node include:
򐂰 IBM Flex System EN2092 1Gb Ethernet Scalable Switch
򐂰 IBM Flex System EN4091 10Gb Ethernet Pass-thru
򐂰 IBM Flex System Fabric EN4093 10Gb Scalable Switch
򐂰 IBM Flex System Fabric EN4093R 10Gb Scalable Switch
򐂰 IBM Flex System Fabric CN4093 10Gb Converged Scalable Switch
򐂰 IBM Flex System FC3171 8Gb SAN Switch
򐂰 IBM Flex System FC3171 8Gb SAN Pass-thru
򐂰 IBM Flex System FC5022 16Gb SAN Scalable Switch
For more information of these modules, refer to 1.5, “I/O Modules” on page 23.
The I/O module will determine the connectivity type of the IBM Flex System V7000 Storage
Node to the compute nodes. The storage node canister must have an appropriate Network
Adapter suitable to the I/O module in order to communicate with the required protocol.
Each of the two node canisters in the IBM Flex System V7000 Storage Node can have up to
two Network Adapter cards. These will connect to the I/O modules so that the Storage Node
can communicate with and present storage to the compute nodes.
Figure 11-1 on page 434 shows the logical connections from the Storage Node canister
Network Adapters to the I/O module switches. Each logical connection shown in the figure
represents four serial links to an I/O module switch. The Network Adapter port uses only one
of these four ‘lanes’ per switch, the unused lanes are provided for future options. Each of
these individual I/O links or lanes can be wired for 1Gb or 10Gb Ethernet, 8 or 16 Gbps Fibre
Channel.
