High-Performance, High-Capacity DAS

The Lenovo Storage D1212 has the flexibility and capacity to handle many different types of workloads. You can start with one D1212 enclosure containing up to 12x 3.5-inch drives as a simple JBOD, and later daisy-chain up to 8 enclosures per SAS Chain (using multiple ports). One chain supports up to 96 drives.

Supported drives include 10,000rpm and 7,200rpm HDDs, secure self-encrypting 7,200rpm SED HDDs, and high-performance/high-capacity SSDs for read-intensive workloads. The D1212 supports RAID-0, 1, 10, 5, 50, 6, and 60, using a variety of RAID HBAs. A single chain can contain a combination of HDDs and SSDs with multiple speeds and capacities. If 15,000rpm and 2.5-inch HDDs are required, D1224 expansion units may be included in the chain.

Best Value for Storage Capacity

The D1212 is optimized for performance at an affordable price. With support for daisy chaining, the D1212 can be scaled up to 1.92 PB for capacity-optimized configurations with HDDs. 10,000rpm 12Gbps SAS drives offer the speed needed for many performance-intensive workloads, and SSDs provide the extreme throughput necessary for the most I/O-intensive jobs, along with high capacity.

The D1212 shares common parts with D1224 DAS enclosures. This simplifies servicing and reduces spare parts on hand, helping to reduce costs further.

Easy to Deploy and Highly Available

Simply cable-connect new units and they come online immediately (OS-dependent) with instant drive identification. Virtual machines can share these expansion chassis as well.

And because storage is useless when it’s offline, the D1212 uses ruggedized components that are designed for 99.999 percent availability and NEBS3 compliance, along with hot-swap drives and hot-swap/redundant power supplies for maximum uptime. Redundant I/O modules with failover complete the package.
