Storwize V7000 terminology
Control enclosure
A hardware unit that includes the chassis with a midplane for connection of node
canisters, drives, and power supply units with batteries
Node canister
A hardware unit that includes the node electronics, fabric, and service interfaces,
serial-attached SCSI (SAS) expansion ports and direct connections to internal
drives in the enclosure
Expansion enclosure
A hardware unit that includes the chassis with a midplane for connection of
expansion canisters, drives, and power supply units without batteries
Expansion canister
A hardware unit that includes the electronics to provide serial-attached SCSI
(SAS) connections to the internal drives in the enclosure and SAS expansion
ports for attachment of additional expansion enclosures
System
Two node canisters in a control enclosure. Up to four control enclosures can be
clustered to form one system.
Managed disk (MDisk)
An SCSI logical unit (also known as LUN) built from an internal or external RAID
array
Internal storage
Physical SAS drives within a Storwize V7000 control or expansion enclosure
used to create RAID arrays and managed disks
External storage
Managed disks that are SCSI logical units (aka LUNs) presented by storage
systems that are attached to the SAN and managed by the system

• Two node canisters (each with an
8-core processors and integrated
hardware-assisted compression
acceleration
• New cache architecture
▪ 64 GB cache per system
(standard)
▪ Optional 128 GB cache per
system for Real-time Compression
workloads
• Host connectivity support:
▪ 8 Gb /16 Gb Fibre Channel (FC)
▪ 10 GbE iSCSI / Fibre Channel
over Ethernet (FCoE), and 1 Gb
iSCSI
• Dual redundant power supplies

• Storwize V7000 nodes are logical nodes.
 One node in the system serves as the configuration node, but any node can
assume the roll of a configuration node.
 Node canisters are active/active storage controllers, where both node canisters
are processing I/O at any time and any volume can be accessed by either node
canister.

System switch port connection
• Supports 2 Gb, 4 Gb, 8 Gb, or 16 Gb FC fabric speeds
• Recommend connecting the Storwize V7000 controller and the
disk subsystem to the switch operating at the highest speed

For 8 Gb connect the
P3 and P4 ports to
the same fabrics as
P1 and P2 ports
respectively.
Connect the P1
ports to one fabric
and the P2-ports
to the other fabric.

Host connection verification
• Verify host HBA using the vendor-supplied to display the Fibre Channel
configuration.
• Verify host zoning using management GUI: Settings > Network > Fibre
Channel.
−Change view connectivity to Hosts and the host name.
• Each host WWPN is zoned with one Storwize V7000 WWPNs per node.
