| Host interface intermix |
- Support for intermixing Fibre Channel and iSCSI interfaces allows for cost-effective SAN tiering
|
| Balanced performance |
- Equally adept at input/output operations per second (IOPS) and MBps, DS3950 is able to support applications with wide-ranging performance requirements
- Well suited for data warehousing, consolidation and virtualization environments that have diverse workloads and application requirements
- Designed to concurrently support transactional applications, such as databases and online transaction processing (OLTP), and throughput-intensive applications, such as high-performance computing (HPC) and rich media
|
| Up to 112 intermixed drives |
- Supports intermixing of Fibre Channel, FC-SAS and SATA disk drives for tiered storage
- Fibre Channel disks can be allocated to applications that demand high performance and have high I/O rates; less-expensive SATA disks can allocated to applications that require less performance. In addition, FC-SAS disks can help ensure data integrity with support for the T10 Protection Information (T10-PI) standard
- Enclosure-based intermixing helps maximize efficiency
|
| Built-in efficiencies |
- Modular design avoids over-configuration for an affordable, entry-point price while offering seamless “pay-as-you-grow” scalability as requirements change
- Efficient utilization lowers raw capacity requirements, and support for intermixing high-performance and high-capacity drives enables tiered storage
- Exceptional per-drive performance creates performance value by getting the most performance out of the fewest drives
|
| IBM System Storage DS Storage Manager software |
- Feature-rich storage management software enables maximum utilization and uninterrupted data availability
- Configuration flexibility supports custom LUN tuning to ensure maximum performance or utilization
- Centralized management of all local and networked based systems
- Quickly configure and monitor storage from a centralized interface
- Configure volumes, perform routine maintenance and add new enclosures and capacity without interrupting access to data
|
| Dynamic expansion capabilities |
- Designed to offer the ability to bring unused storage online for a new host group or an existing volume to provide additional capacity on demand
- Designed to eliminate application interruptions due to growth, reconfigurations or tuning
|
| Up to 128 partitions |
- Effectively support medium-scale consolidation or virtualization environments—thus helping to reduce hardware and storage management costs
|
| Fully-integrated replication features |
- Multiple replication options allow administrators to deploy the one that best fits their needs
- Local or remote copies can be used for file restoration, backups, application testing, data mining or disaster recovery
|
| Support for heterogeneous, open operating systems |
- Support for Microsoft Windows, UNIX and Linux systems enables the storage system to operate in a variety of open-system environments
|
| Custom XOR engine for RAID-parity calculations |
- Efficiently handles compute-intensive parity calculations enabling exceptional disk-based performance that’s ideally-suited for RAID 5 and RAID 6 configurations
|
| Support for multiple RAID levels; including RAID 6 |
- Designed to support high availability and security for mission-critical data
- Offers flexibility to configure the system to address varying service levels
|
| Redundant, hot-swappable components |
- Designed to maintain data availability by allowing components to be replaced without stopping I/O
|
| Persistent cache backup |
- Ensures any data in cache is captured and safe in the event of a power outage
|
| Up to four 8 Gbps Fibre Channel host ports |
- Designed to deliver high bandwidth for the most demanding applications
- Provides up to 3,200 MBps cache burst rate for high-throughput applications through the four channels
|
| Backward compatibility with 2 Gbps and 4 Gbps devices |
- Plan for the future while leveraging current investments
- Auto-negotiate connection speed to ease configuration in mixed environments
|
| Up to 112 Fibre Channel drives |
- Upgrade from a workgroup SAN to an enterprise network storage system with a single DS3950 Express
|
| T10-PI data integrity |
- Help assure customers with ultra-sensitivity to data validation that every I/O is safeguarded every step of the way, from application to disk
|
| Dynamic capacity expansion |
- Add EXP395 enclosures to an existing DS3950 Express without stopping operations
- Bring unused storage online for a new host group or an existing volume to provide additional capacity on demand
|
| Dynamic volume expansion |
- Expand logical volumes without disrupting operations
