Lenovo Storage D1212 and D1224 Drive Enclosures

Product Guide

The Lenovo Storage D1212 and D1224 Disk Expansion Enclosures offer 12 Gbps SAS direct-

attached storage expansion capabilities that are designed to provide simplicity, speed, scalability, security,

and high availability for small to large businesses. The D1212 and D1224 deliver enterprise-class storage

technology in a cost-effective solution with flexible drive configurations and RAID or JBOD (non-RAID) host

connectivity.

The D1212 and D1224 expansion units are designed for a wide range of workloads, including big data and

analytics, video surveillance, media streaming, private clouds, file and print serving, e-mail and

collaboration, and databases. They also well-suited for software defined storage (SDS) and Windows

Server solutions with Storage Spaces.

Did you know?

The D1212 and D1224 expansion enclosures offer flexible drive configurations with the choice of 2.5-inch

and 3.5-inch drive form factors, 10K or 15K rpm SAS and 7.2K rpm NL SAS hard disk drives (HDDs) and

self-encrypting drives (SEDs), and SAS solid-state drives (SSDs).

With support for daisy chaining, the D1212 can be scaled up to 960 TB for capacity-optimized

configurations with HDDs, and the D1224 can be scaled up to 192 drives for performance-optimized

configurations.

The D1212 and D1224 expansion units support 12 Gbps SAS connectivity, which doubles the data

transfer rate compared to 6 Gb SAS solutions to maximize performance of storage I/O-intensive

applications.

Documentation package

Host connectivity

The D1212 and D1224 drive enclosures support dual environmental service module (ESM) configurations.

Each ESM has three 12 Gb SAS x4 ports (Mini-SAS HD SFF-8644 connectors) labeled A, B, and C. These

ports are used for connections to a supported RAID adapter or HBA installed in a server and for daisy

chaining the D1212 and D1224 enclosures between each other.

Port A on each ESM is used for connecting the external SAS ports on the RAID controller or HBA to the

enclosure, or for connecting Port C on each ESM in the adjacent enclosure for daisy chaining.

Port B on each ESM is used for connecting the external SAS ports on the RAID controller or HBA to the

enclosure. Daisy-chaining does not use Port B for connections between adjacent enclosures.

Port C on each ESM is used for connecting the external SAS ports on the RAID controller or HBA to the

enclosure, or for connecting Port A on each ESM in the adjacent enclosure for daisy chaining.

Up to eight D1212 or D1224 drive enclosures, or a combination of both, can be daisy-chained with

support for up to four hosts attached to the chain. Without daisy-chaining, a standalone

D1224 drive enclosure can support up to six directly attached hosts.

Lenovo Storage D1212 and D1224 Drive Enclosures 7

The following figures illustrate different host connectivity topologies.

Figure 5. Connectivity topology with one host

Figure 6. Connectivity topology with two hosts

Lenovo Storage D1212 and D1224 Drive Enclosures 8

Figure 7. Connectivity topology with four hosts

For topologies with four or more hosts, SAS Y-cables are required to connect the hosts to the drive

enclosure. The SAS Y-cable allows two hosts be connected to one SAS port on the ESM. The Y-cables

and standard cables are mutually exclusive, that is, either Y-cables or standard cables can be used to

connect the hosts to the same drive enclosure, but not both.

The SAS zoning feature of the D1212 and D1224 specifies how multiple hosts access drives in the

enclosures. If SAS zoning is disabled, all attached hosts can access all drives in the enclosures, which is

typically used in standalone single-host or clustered multi-host environments, where all cluster nodes need

access to all drives. If SAS zoning is enabled, each connected host has exclusive access to a predefined

set of drives, and multiple hosts are isolated from each other.

Note: Attachment of more than one host to the same enclosure without SAS zoning is supported with

HBAs only (RAID controllers are not supported). While all attached hosts are capable of accessing all

drives in the enclosures, the clustering software running on the hosts controls which cluster nodes have

access to the drives at any given time.

The supported zone configurations are shown in the following table.

Note: Mode 0 means that zoning is disabled.
