| DS Storage Manager |
- Full-time storage administrators achieve complete control over their storage configuration and part-time users have an intuitive and simple interface
- Centralised management of all local and networked IBM System Storage DS5000, IBM System Storage DS4000 and DS3500 Express storage systems – means increased management efficiencies and a reduced learning curve with simple management
- Investment protection with optional Disaster Recovery (DR) option delivering enhanced remote mirroring support across FC or IP host interfaces
|
| Host interface intermix |
- Support for intermixing SAS and FC or SAS and iSCSI interfaces enables cost-effective SAN tiering and consolidation
|
| Balanced performance |
- Equally adept at IOPS and megabytes per second (MBps), the DS3500 Express supports applications with wide-ranging performance requirements
- Well suited for consolidation and virtualisation environments that have diverse workloads and application requirements
- Designed to support transactional applications and throughput-intensive applications concurrently
|
| Data protection |
- DDP offers simplified installation, greater data protection and more consistent performance than traditional redundant array of independent disk (RAID) options
- RAID levels 0, 1, 3, 5, 6 and 10 give you the flexibility to choose the level of protection required
|
| 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 save storage capacity, no longer requiring users to purchase all storage up front for each request
|
| IP replication |
- Provides mirroring over internet protocol (IP) networks to replicate data for DR on storage via inexpensive link
|
| Complete testing and integration |
- With its simple, efficient and flexible approach to storage, the DS3500 Express is a cost-effective, fully integrated complement to System x, BladeCenter and Power Systems servers
|
| Support for SED drives |
- Comprehensive protection for data-at-rest ensures data is secured throughout the drive’s lifecycle without sacrificing performance or ease of use
|
| Scalability up to 192 drives |
- Provides the flexibility to grow with your data needs
- Not locked into high quantity drive purchase at initial purchase
|
| Support for drive intermix |
- Ability to intermix high performance SAS, SAS-NL, SAS, SSDs and SED drives enables tiered storage
- Cost-effectively supports an organisation’s complete range of data capacity requirements – from NL to highly used applications – with support for mixed drive types within a single storage system
- Enclosure-based intermixing maximises efficiency
|
| SAS-NL drives support |
- SAS-NL drives significantly outperform serial advanced technology attachment (SATA) and do so with greater reliability, for a comparable price
|
| 2.5 in. and 3.5 in. drive support |
- Additional drive flexibility supports both high performance and great IOPS/Watt requirements
- Tray-level drive intermix cost-effectively meets all application, rack and energy-efficiency requirements within a single storage system
|
| SSD support |
- The SSDs supported by the DS3500 Express can be used to improve application performance while simultaneously reducing power and cooling requirements
|
| Superb disk utilisation use |
- Achieve great performance with fewer drives
- Lower drive investment and reduce heat dissipation
|
| Support for greater than 2 terabytes (TB) of logical unit numbers (LUNs) |
- Maximises capacity use for applications that need to move large amounts of data with maximum throughput performance
|
| Built-in efficiencies |
- Modular design avoids over-configuration for an affordable entry point while offering seamless 'pay-as-you-grow' scalability as requirements change
- Efficient utilisation lowers raw-capacity requirement and support for intermixing drives enables tiered storage
- Exceptional per-drive performance creates performance value by getting the most performance out of the fewest drives
|
| DS3500 Express DC model |
- Meets the standard -48 V DC requirements of telecommunications and related industries
- A NEBS/ETSI-compliant storage system provides assurance of resiliency in the most intense and harsh environments
|
| Redundant, hot-swappable components |
- Fully redundant components, automated input/output (I/O) path failover and online administration that create 'always-on' availability to ensure data is always accessible
|
| Optional premium features |
Simplifies ordering of software features:
- DR option provides 16 Enhanced Remote Mirrors and 32 Enhanced Global Mirrors; offering multiple options for DR deployment, this feature supports replication over FC or IP
- Backup and Restore option allows 512 Enhanced FlashCopy images on the DS3500 system; IBM Enhanced FlashCopy technology delivers easier setup of shared vs. dedicated repositories and reduced capacity requirements and copy-on-write capacity consumption
- Performance Read Cache option utilises SSDs as a level-two data cache, significantly improving read performance off of spinning media; Performance Read Cache 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
- Super Key option combines all of the above features into one single key for easy deployment and management of these features
- Turbo Performance option key provides up to a two times performance boost to the system
- Drive Expansion option enables attachment of drives over 96 drive base offering to 192 drives
|
| Online firmware upgrades |
- Firmware upgrades can occur while data accessibility continues in dual controller configurations
- Organisational productivity and customer satisfaction is assured with data available around-the-clock
