To ensure your cloud and data are kept safe, you need the security, scalability and efficiency of LinuxONE.

IBM® System Storage DS8000® series is a high-performance, high-capacity series of disk storage that supports continuous operations.

The latest and most advanced disk enterprise storage system in the DS8000 series is the IBM System Storage® DS8870. It represents the latest in the series of high-performance and high-capacity disk storage systems. The DS8870 supports IBM POWER7® processor technology to help support higher performance.

The DS8000 series DS8870 supports functions such as point-in-time copy functions with IBM FlashCopy®, FlashCopy Space Efficient, and Remote Mirror and Copy functions with Metro Mirror, Global Copy, Global Mirror, Metro/Global Mirror, IBM z/OS® Global Mirror, and z/OS Metro/Global Mirror. Easy Tier® functions are supported on DS8870 storage units. I/O Priority Manager is also supported on the DS8870 units.

All DS8000 series models consist of a storage unit and one or two management consoles, two being the recommended configuration. The graphical user interface (GUI) or the command-line interface (CLI) provide the ability to logically partition storage and use the built-in Copy Services functions. For high-availability, the hardware components are redundant.

The Tivoli® Key Lifecycle Manager (TKLM) software performs key management tasks for IBM encryption-enabled hardware, such as the DS8000 series by providing, protecting, storing, and maintaining encryption keys that are used to encrypt information being written to, and decrypt information being read from, encryption-enabled disks. TKLM operates on a variety of operating systems.
