| Up to 60 nearline SAS drives in 4U |
- Maximise rack space efficiency and reduce costs with 60 nearline SAS drives in 4U expandable to 180 drives or 360 drives with IBM DCS3700 with Performance Modules option
- Lower overall annual energy expenditures with 45 TB per U providing highly efficient enclosures
|
| Redundant, hot-swappable components |
- Ensure your data is always accessible with fully redundant components, automated I/O path failover and online administration
- Extend front-load, 12-drive drawers while drives remain active
|
| 6 Gbps SAS host interface (standard on base DCS3700 system and optional on DCS3700 with Performance Modules system) |
- Helps improve bandwidth utilisation, management and network robustness
- Second-generation, 6 Gbps SAS builds upon the solid foundation of 3 Gbps SAS with performance improvements and reliability enhancements
- Direct attachment support and the capability to be shared by multiple host servers offers ease of use and simplicity at an affordable price
|
| 8 Gbps Fibre Channel host interface (standard on DCS3700 with Performance Modules system and optional on base DCS3700 system) |
- Fibre Channel, a mature and proven technology now available at 8 Gbps, is the host interface of choice for high-performance environments
|
| 10 Gbps iSCSI host interface (optional on DCS3700 with Performance Modules system) |
- 10 Gbps Ethernet infrastructures are pervasive throughout the IT industry and enable cost effective deployment of IP networking for storage and/or disaster recovery implementations.
|
| Backup and replication capabilities |
- 32 IBM Enhanced FlashCopy images are included per storage system to support granular backup and recovery and reduce backup times
- Backup and Restore option increases the number of Enhanced FlashCopy images to 512 for base DCS3700 and 2,048 for the DCS3700 with Performance Modules system
- Disaster Recovery option delivers enhanced Global Mirroring with checkpoint-based asynchronous mirroring to provide storage system automatic resynchronization from primary DCS3700 storage system to secondary over Fibre Channel or IP (for DCS3700 with Performance Modules system) communication links
|
| Data protection |
- New Dynamic Disk Pooling offers simplified installation, greater data protection and more consistent performance than traditional RAID options
- RAID levels 0, 1, 3, 5, 6 and 10 provide flexibility to choose the level of protection required
|
| Storage partitions |
- Storage partitions logically divide a single DCS3700 storage system into multiple systems to manage volume-to-host access
- The base DCS3700 has 128 storage partitions included standard with firmware 7.84 or later
- The DCS3700 with Performance Modules system has 512 storage partitions included standard with firmware 7.84 or later
|
| Drive intermix support |
- Supports intermixing of SSDs, high-performance SAS drives and nearline SAS drives
|
| Intuitive IBM DS Storage Manager |
- A powerful yet easy-to-use and intuitive graphical user interface for DCS3700 administrative activities
- Includes configuration, reconfiguration, expansion and routine maintenance, as well as performance tuning and management of advanced functions
|
| Thin provisioning with DDP |
- Thin provisioning is designed to manage storage space and avoid unused resources
- No more unnecessary storage expenses: thin provisioning can help to save storage capacity, helping to remove the need to purchase all storage up front for each request
|
| Performance |
- Performance Read Cache option utilises SSDs as a level two data cache, significantly improving read performance from spinning media; this option is extremely easy to set up and, once implemented, automatically identifies the data that is read most frequently and copies it into cache for fast access
|
| Energy-saving features |
- Power supplies are designed to meet multiple efficiency standards and variable speed fans help reduce power consumption and provide a lower overall total cost of ownership
- Optimised for maximum storage density, with 60 drives housed within just a 4U enclosure
