IBM System Storage DS Storage Manager
- Full-time storage administrators achieve complete control over their storage configuration, and part-time users have an intuitive and simple interface
- Centralized 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 option delivering enhanced remote mirroring support across Fibre Channel or IP host interfaces
- Auto Support feature allows centralized collection and reporting of key operational statistics for ongoing trend analysis and product improvement
Host interface intermix
- Support for intermixing SAS and Fibre Channel or SAS and iSCSI interfaces enables cost-effective SAN tiering and consolidation
Balanced performance
- Equally adept at IOPS and megabytes per second, DS3500 Express supports applications with wide-ranging performance requirements
- Well suited for consolidation and virtualization environments that have diverse workloads and application requirements
- Designed to support transactional applications and throughput-intensive applications concurrently
Data protection
- Dynamic Disk Pooling (DDP) offers simplified installation, greater data protection and more consistent performance than traditional 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 Ethernet to replicate data for disaster recovery on storage via inexpensive link
Complete testing and integration
- With its simple, efficient and flexible approach to storage, 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
T10-PI data integrity
- Helps assure customers with ultra-sensitivity to data validation that every I/O is protected every step of the way, from application to disk
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, nearline SAS, SAS, SSDs and SED drives enables tiered storage
- Cost-effectively supports an organization’s complete range of data capacity requirements—from nearline to highly used applications—with support for mixed drive types within a single storage system
- Enclosure-based intermixing maximizes efficiency
Nearline SAS drives support
- Nearline SAS drives significantly outperform SATA and do so with greater reliability, for a comparable price
2.5-inch and 3.5-inch 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 DS3500 Express can be used to improve application performance while simultaneously reducing power and cooling requirements
Superior disk utilization use
- Achieve great performance with fewer drives
- Lower drive investment and reduce heat dissipation
Support for greater than 2 TB of logical unit numbers
- Maximizes 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 utilization lowers raw-capacity requirement, and support for intermixing drives enables tiered storage
- Exceptional per-drive performance creates strategic value by delivering 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 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:
- Disaster Recovery option provides 16 Enhanced Remote Mirrors and 32 Enhanced Global Mirrors; offering multiple options for disaster-recovery deployment, this feature supports replication over Fibre Channel 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 utilizes 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
- Organizational productivity and customer satisfaction is assured with data available 24×7
