    • Metro Mirror (synchronous copy)
    • Global Mirror (asynchronous copy)
    • Data migration
  • Space management:
    • Easy Tier function to migrate the most frequently used data to higher-performance storage
    • Metering of service quality when combined with Spectrum Control Base Edition. For information, refer to the Spectrum Control Base Edition documentation.
    • Thin-provisioned logical volumes
    • Compressed volumes to consolidate storage

Figure 1 shows a Lenovo Storage V series system as a traditional RAID storage system. The internal drives are configured into arrays. Volumes are created from those arrays.

Figure 1. Lenovo Storage V series system as a RAID storage system
This figure shows an overview of a RAID storage system.

The two node canisters are known as an I/O group. The node canisters are responsible for serving I/O on the volumes. Because a volume is served by both node canisters, no availability is lost if one node canister fails or is taken offline. The Asymmetric Logical Unit Access (ALUA) features of SCSI are used to disable the I/O for a node before it is taken offline or when a volume cannot be accessed via that node.

Volumes types

You can create the following types of volumes on the system.
  • Basic volumes, where a single copy of the volume is cached in one I/O group. Basic volumes can be established in any system topology; however, Example of a basic volume shows a standard system topology.
    Figure 2. Example of a basic volume
    This figure shows an example of a basic volume in a standard system configuration.
  • Mirrored volumes, where copies of the volume can either be in the same storage pool or in different storage pools. The volume is cached in a single I/O group, as Example of mirrored volumes shows. Typically, mirrored volumes are established in a standard system topology.
    Figure 3. Example of mirrored volumes
    This figure shows an example of a mirrored volume in a standard system configuration.
  • HyperSwap volumes, where copies of a single volume are in different storage pools that are on different sites. As Example of HyperSwap volumes shows, the volume is cached in two I/O groups that are on different sites. These volumes can be created only on Lenovo Storage V5030 and Lenovo Storage V5030F systems when the system topology is HyperSwap.
    Figure 4. Example of HyperSwap volumes
    This figure shows an example of HyperSwap volumes in a HyperSwap system configuration.

System topology

The topology property of a system can be set to one of the following states:

The node canisters can be arranged in different topologies.

Note: You cannot mix I/O groups of different topologies in the same system.

System management

The Lenovo Storage V series nodes operate as a single system and present a single point of control for system management and service. System management and error reporting are provided through an Ethernet interface to one of the nodes in the system, which is called the configuration node. The configuration node runs a web server and provides a command-line interface (CLI). The configuration node is a role that either node can take. If the current configuration node fails, the other node becomes the configuration node. Each node also provides a command-line interface and web interface for servicing hardware.

Fabric types

I/O operations between hosts and Lenovo Storage V series nodes and between Lenovo Storage V series nodes and RAID storage systems use the SCSI standard. The Lenovo Storage V series nodes communicate with each other by using private SCSI commands.

Fibre Channel and Fibre Channel over Ethernet (FCoE) connectivity is supported on Lenovo Storage V series system with the optional FCoE feature installed.

Lenovo Storage V series communications types shows the fabric types that can be used for communicating between hosts, nodes, and RAID storage systems. All installed fabric types can be used at the same time.

Table 3. Lenovo Storage V series communications types
Communications type Host to Lenovo Storage V series Lenovo Storage V series to storage system
iSCSI (1 Gbps Ethernet) Yes No
iSCSI (10 Gbps Ethernet) Yes
Note: Lenovo Storage V3700 V2 and Lenovo Storage V3700 V2 XP systems must have the optional 10 Gbps Ethernet host interface adapter to use Ethernet for host attachment. Lenovo Storage V5030 and Lenovo Storage V5030F systems have a 10 Gbps Ethernet port that is preinstalled on the system for host attachment.
 No
iSCSI (25 Gbps Ethernet) Yes No
Fibre Channel over Ethernet Yes, with 10 Gbps Ethernet host interface adapter Yes, with 10 Gbps Ethernet host interface adapter
