The following functions are included with every ThinkSystem DE4000H:

• RAID levels 0, 1, 3, 5, 6, and 10: Provide the flexibility to choose the level of performance and data protection required.
• Dynamic Disk Pools (DDP) technology: Helps improve performance and availability with significantly faster rebuild time and reduced exposure to multiple drive failures by allowing data and built-in spare capacity to be distributed across all physical drives in the storage pool.
• All Flash Array (AFA) capability: Meets the demand for higher speed storage and provide higher IOPS and bandwidth with lower power usage and total cost of ownership than hybrid or HDD-based solutions.
• SSD Read Cache: Helps accelerate performance of read-centric workloads.
• Thin provisioning: Optimizes efficiency of Dynamic Disk Pools by allocating storage space based on the minimum space required by each application at any given time, so that applications consume only the space they are actually using, not the total space that has been allocated to them, which allows customers to purchase storage they need today and add more as application requirements grow.
• Snapshots: Enables creation of copies of data for backup, parallel processing, testing, and development, and have the copies available almost immediately. Base software supports up to 128 snapshot targets per system.
• Encryption: Provides encryption for data at rest for enhanced data security with the optional FIPS drives and embedded key management or an external key management server.
• Automatic load balancing: Provides automated I/O workload balancing of I/O traffic from the hosts across both controllers.
• Data assurance: Ensures industry-standard T10-PI end-to-end data integrity in the storage system (from the host ports to the drives).
• Dynamic volume and capacity expansion: Allows the capacity of a volume to be expanded by adding new physical drives or making use of unused space on existing drives.

The ThinkSystem DE4000H capabilities can be expanded with optional licensed functions. Optional licensed functions include:

• Snapshots upgrade: Increase the supported number of snapshot targets to 512.
• Synchronous mirroring: Provides storage system-based online, real-time data replication between the storage systems containing primary (local) and secondary (remote) volumes by using synchronous data transfers over Fibre Channel communication links (both storage systems must have licenses for synchronous mirroring).
• Asynchronous mirroring: Provides storage system-based data replication between the storage systems containing primary (local) and secondary (remote) volumes by using asynchronous data transfers over iSCSI or Fibre Channel communication links at set intervals (both storage systems must have licenses for asynchronous mirroring).

Note: The synchronous and asynchronous mirroring features of the ThinkSystem DE4000H interoperate with other ThinkSystem DE Series storage arrays.

Software maintenance is included in the ThinkSystem DE4000H base warranty and optional warranty extensions, which provides 3-year software support with the option to extend it up to 5 years in 1-year or 2-year increments (see Warranty and support for details).

The ThinkSystem DE4000H supports the following management interfaces:

• Lenovo System Manager, a web-based interface via HTTPS for single-system management, that runs on the storage system itself and requires only a supported browser (Microsoft Internet Explorer, Google Chrome, or Mozilla Firefox), so there is no need for a separate console or plug-in.
• Lenovo SAN Manager, a host-installed GUI-based application, for centralized management of multiple storage systems.
• Command line interface (CLI) via SSH or through serial console.
• Syslog, SNMP, and e-mail notifications.
