You choose the conhroller to match your current performance requirements and budget, and IBM offers a way to protect your investment with an upgrade path to later add the options you need. The DS flexibility and options also extends to the disk drives. The DS is available in two models: Disk drives of the same form factor can be intermixed within the appropriate DS or EXP enclosure.
The DS carries on the tradition of DS series data protection features with support for multiple RAID levels 0 1, 3, 5, 6, and 10ztorage partitions to manage volume-to-host access, and FlashCopy and Volume Copy to create logical or physical copies of your data. The DS brings the following new functions ztorage the DS series ccontroller The DS delivers affordable, entry-level configurations for small and medium businesses in compact 2U, inch rack mount enclosures, with the flexibility to scale in capacity, performance, host interfaces, and advanced functions as your business grows or requirements change.
The DS is available in the following models: Contact your IBM sales representative or business partner to obtain a copy of the test result documents.
New technology delivers new levels of performance The DS combines next-generation controller technology with the latest, high-performance host interface technologies to deliver new levels of performance to the DS series.
This balanced performance, combined with the ability to handle concurrent workloads, makes the DS a great fit for consolidation and virtualization environments. With the DS, you choose the initial system configuration that matches your performance requirements and budget: The DS with a single controller provides an entry solution with low initial investment The DS with dual controllers offers higher performance The DS dual controller with the Turbo Performance option offers the highest level of performance Furthermore, the ability to later upgrade your DS to dual controllers and Turbo performance options offers a way to protect your initial investment in a DS entry solution.
Along with 1 Gb per second iSCSI support and the capability to intermix host interface technologies, the DS is designed to address your shared storage requirements within a single system.

With direct attachment support and the capability to be shared by multiple host servers, the DS with SAS provides ease-of-use and simplicity at an affordable price. Fibre Channel, a mature and proven technology now available at 8 Gb, is the host interface of choice for high performance environments. SAS host interface ports are standard on all DS models.
The following configurations are available: High-performance, enterprise class drives 3. Up to disk drives are supported by a single DS storage system with attachment of EXP expansion units, doubling the scalability available, offered by the other DS products. Additional disk drives and expansion units are designed to be dynamically added with virtually no downtime, helping you to quickly and seamlessly respond to your ever-growing capacity demands.
This gives you the added flexibility to mix 3. Energy saving implementations for 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: High-efficiency power supplies designed to meet power efficiency standards for reduce power consumption Small form factor 2.
This reduces the number of disk drives needed to meet performance and capacity demands, resulting in lower acquisition and operational expenditures. High availability with new data protection and security options The DS carries on the DS series legacy of high system and data availability with: Dual-active, intelligent array controllers with mirrored cache Dual port disk drives with automatic disk drive failure detection and rebuild with global hot spares Redundant hardware, including power supplies and fans Hot-swappable and customer replaceable components Automated path failover support for the data path between the server and the disk drives And, the DS carries on the tradition of DS series data protection features with: RAID levels 0, 1, 3, 5, 6, and 10 provide you the flexibility to choose the level of protection required 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: Remote Mirroring to provide storage system-based data replication from one DS system to another DS system using either synchronous or asynchronous data transfers over Fibre Channel communication links.
Full Disk Encryption FDE provides local key management and disk drive-level encryption for comprehensive data security and protection. The DS locally manages and protects the self-encrypting drives SED by utilizing a single authorization scheme or lock key that can be set and applied to all SED drives within a DS The DS Storage Manager maintains and controls the key linkage and communications with the SED drives, secures user-selected logical drive groups, and can even initiate an instant secure erase feature when servicing, decommissioning, or repurposing drives.
The DS FDE engine performs encryption without a performance penalty, which allows you to achieve new levels of data security without sacrificing performance. With these encryption services, FDE key management is transparent to day-to-day storage administration, making SED drives as easy to manage as traditional drives. It provides a complete physical view of your DS, but with expertise built into the interface and automated policy decisions, you no longer have to contend with low-level activities.
Rich set of data replication functions for business continuity needs FlashCopy creates a capacity-efficient, point-in-time copy of a physical volume for data protection uses, such as file restoration and backup. A FlashCopy volume is the logical equivalent of the physical volume, but is created more quickly than a physical copy and with minimal disruption to applications and production processes. Using copy-on-write technology, FlashCopy volumes preserve data in its original form even as data in the physical source volume is changed.
FlashCopy volumes appear and function as standard storage volumes, and restoration of a FlashCopy volume is quick and easy. Volume Copy creates a physical copy of a volume. Volume Copy is used with FlashCopy to create a physical copy of your data with minimal disruption to applications and production processes.
Upon completion of the Volume Copy process, the new volume can be mapped to any host and functions as a standard volume. Remote Mirroring provides storage system-based data replication from one DS system to another DS system over Fibre Channel communications links. Remote Mirroring supports synchronous or asynchronous data transfers, enabling you to choose the replication method that best meets your protection, distance, or performance requirements: Synchronous mirroring is designed to provide continuous mirroring between primary and remote volumes to help ensure absolute synchronization.
Asynchronous mirroring queues remote writes to reduce the latency, thus enabling long distance replication while increasing local system performance. Asynchronous mirroring includes a write consistency option designed to ensure that writes to the remote system complete in the same order as the local system.
