Upon completion of the Volume Copy process, the new volume can be mapped to any host and functions as a standard volume. This gives you the added flexibility to mix 3. Refer to the Chargeable section for feature numbers contorller part numbers: When installed on a DS dual controller system, both cards must be configured to run at the same link speed.
Base 68Y Remote Mirroring: Supported on dual controller systems only: Additional transceivers can be ordered using feature PN 69Y Features – No charge. Windows is a trademark of Microsoft Corporation. This cable must be customer-supplied and is not available for ordering with the DS Feature PN 68Y is required to utilize the self encryption capability. For example with controller firmware level Mutually exclusive with feature PN 68Y RAID levels 0, 1, 3, 5, 6, and 10 Maximum volumes per system: The following cable types and cable lengths are supported: If ordered, feature quantity must equal two of the same type.

Disk drives of the same form factor can be intermixed within the appropriate DS or EXP enclosure. Base No Longer Available as of June 21, This feature provides ststem activation key to increase the quantity of FlashCopy images supported per physical volume from two to four, with: Full Disk Encryption FDE provides local key management and disk drive-level encryption for comprehensive data security and protection.
Supported on ac-powered models only. Supported on Model C2A only. Refer stoorage the Product Number section for feature numbers and part numbers: Both ports on a shstem will run at the same link speed. RAID levels 0, 1, 3, 5, 6, and 10 provide you the flexibility to choose the level of protection storagge Storage partitions that logically divide a single DS into multiple systems to manage volume-to-host access FlashCopy and Volume Copy to create logical or physical copies of data for file restoration and backup The DS brings the following new data protection and data security options into the DS series family: The DS FDE engine performs encryption without a performance penalty, which allows you to achieve new levels of data security without sacrificing performance.
Base No Longer Available as of June 21, This feature provides storzge activation key to the enable the Remote Mirror function with support for eight mirror pairs per system. The DS flexibility and options also extends to the disk drives.
Asynchronous mirroring queues remote writes to reduce the latency, thus enabling long distance replication while increasing local system performance. Energy saving implementations stoage cost savings today and tomorrow The DS was developed with energy savings features designed to help reduce power consumption and provide a lower overall total cost of ownership: This card can be configured to run at either a 1Gb or 10Gb link speed.
