All of these features combine to create a system you can trust your data to.

Increase performance

The DS5020 offers high-performance storage to help manage compute-intensive workloads. It is a great t for both transaction-oriented and bandwidth-intensive applications. The DS5020 is also a great choice for environments with intense replication requirements, because it can efficiently handle the additional performance demands of FlashCopy, VolumeCopy and Enhanced Remote Mirroring.
The DS5020 Express Model 20A has up to eight independent 8 Gbps Fibre Channel (FC) host ports for direct attachment to servers or fabric attachment to SANs. One of the rst enterprise-class storage systems based on 8 Gbps FC technologies, the DS5020 can help you prepare for the future while making the most of your current infrastructure. It provides auto-negotiate FC connection speeds, allowing integration into an existing 2 Gbps or 4 Gbps infrastructure. The storage system can also deliver performance and connectivity improvements, while helping you prepare for when the SAN inevitably becomes 8 Gbps. The four 4 Gbps drive connections support up to 112 disk drives with up to six attached EXP520 disk enclosures. The DS5020 Express is designed to support more than 50.4 TB of Fibre Channel physical storage capacity. The DS5020 is available with up to 4 GB of physical cache memory (2 GB per controller). The DS5020 runs the same robust, yet intuitive storage management software as previous storage systems in the series. It is designed to allow maximum utilization of storage capacity and complete control over a rapidly growing storage environment. In the same way customers have beneted from tiered storage (using high-performance FC drives for primary storage and low-cost SATA drives for secondary storage), they can now benet from tiered SANs. IBM DS series storage systems offer high performance, highly reliable FC interfaces for production servers, and low-cost iSCSI interfaces for secondary servers. This combination allows customers to implement a single storage system to support all their shared storage requirementsmaximizing productivity, reliability and costs.
