Features and Benefits
- SAS zoning support up to 6 hosts with Y cables
- A simple, affordable, easy-to-deploy storage expansion solution.
- Use one D1224 as a stand-alone JBOD, or daisy-chain up to 7 more per HBA. This provides access for up to 192 HDDs or SSDs using only one HBA.
- Up to 8 D1224 enclosures are supported per SAS Chain
- Each D1224 contains 24 hot-swap 2.5-inch bays, supporting HDDs and SSDs. This means a maximum of 192 drives/384TB supported per HBA
- Available drives include enterprise-class 15,000rpm SAS HDDs, 10,000rpm SAS HDDs, high-capacity nearline (NL) 7,200rpm SAS HDDs, and high-performance/high-capacity SAS SSDs.
- Each enclosure includes dual SAS I/O modules. Each module includes three 12Gb SAS ports (IN and OUT)—six total per enclosure. Using only two ports enables an enclosure to be daisy-chained to the ones before and after it. Using both SAS I/O modules enables high availability.
- Integrates seamlessly with all Lenovo servers.
- High availability via dual I/O modules, redundant PSUs, and hot-swap drives.
- An effective storage solution for workloads such as data backup, data caching, video surveillance, media streaming, email hosting, server virtualization, file management, and print serving.
- Ideal for cost-sensitive customers, space-constrained environments, current and future high-capacity needs, and server/storage virtualization. It reduces the burden on over utilized internal server storage, and offers extreme capacity for archive and cold storage solutions.
- Shares common parts with the D1212 DAS unit.
High-Performance, High-Capacity DAS
The Lenovo Storage D1224 has the flexibility and capacity to handle many different types of workloads. You can start with one D1224 enclosure containing up to 24x 2.5-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 192 drives.
Supported drives include 15,000, 10,000 and 7,200rpm HDDs, secure self-encrypting 10,000rpm SED HDDs, and high-performance/high-capacity SSDs for read-intensive workloads. The D1224 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 3.5-inch HDDs are required, D1212 expansion units may be included in the chain.
Best Value for Storage Capacity
The D1224 is optimized for performance at an affordable price. 2.5-inch NL drives offer up to 48TB of “cold” or archive storage and 384TB per HBA in 8 enclosures. 10,000 and 15,000 rpm 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 D1224 shares common parts with D1212 DAS enclosures, simplifying servicing and reducing 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 D1224 uses ruggedized components that are designed for 99.999 percent availability, along with hot-swap drives and HS/redundant power supplies for maximum uptime. Redundant I/O modules with failover completes the package.
