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.
