Note: The Relationship models of the ThinkSystem DE4000F listed in this section ship without SFP+/SFP28 optical transceivers or DAC cables; they should be purchased for the system (see Controllers for details).

The ThinkSystem DE4000F controller enclosures ship with two DE4000 controllers. A controller provides interfaces for host connectivity, management, and internal drives, and it runs storage management software. Each DE4000 controller ships with 32 GB memory for a system total of 64 GB.

Each controller has one expansion slot for a host interface card (HIC).

The following host interfaces can be added to the ThinkSystem DE4000F controller enclosures with HICs:

• 8x 12 Gb SAS x4 (Mini-SAS HD SFF-8644) ports (4 ports per HIC) for SAS connectivity
• 8x 10/25 GbE SFP28 ports (4 ports per HIC) for 10/25 Gb iSCSI connectivity (require optical transceivers or DAC cables that should be purchased for the HICs)
• 8x 1/10 Gb iSCSI or 4/8/16 Gb FC SFP+ ports (4 ports per HIC) for iSCSI or FC connectivity (require transceivers or DAC cables [10 Gb iSCSI only] that should be purchased for the HICs)
• 8x 8/16/32 Gb FC SFP+ ports (4 ports per HIC) for FC connectivity (require optical transceivers that should be purchased for the HICs)

Each DE4000 controller also provide two 12 Gb SAS x4 expansion ports (Mini-SAS HD SFF-8644 connectors) for the attachment of the ThinkSystem DE Series expansion units.

Configuration notes:

• Both controllers must have the same system memory size, 32 GB.
• Two host interface cards are required for selection (one per controller).
• Both controllers must have the same type of the host interface card installed (12 Gb SAS SFF-8644, 10 Gb iSCSI / 16 Gb FC SFP+, 10/25 Gb iSCSI SFP28, or 32 Gb FC SFP+), and both cards must have SFP+/SFP28 media of the same type (either optical transceivers or DAC cables, but not both types).

The following table lists the DE4000F controller and supported connectivity options.

The ThinkSystem DE4000F supports attachment of up to three ThinkSystem DE240S 2U24 SFF expansion enclosures. The expansion enclosures can be added to the system non-disruptively.

The following table lists the relationship models of the supported ThinkSystem DE240S expansion enclosures.

Note: The Relationship and TopSeller models of the ThinkSystem DE240S listed in this section ship with four 1 m SAS cables; additional SAS cables that are listed in this section can be purchased for the system, if needed.

Each ThinkSystem DE Series expansion enclosure ships with two SAS I/O expansion modules. Each I/O expansion module provides four external 12 Gb SAS x4 ports (Mini-SAS HD SFF-8644 connectors labelled Port 1-4) that are used for connections to the ThinkSystem DE4000F and for daisy chaining the expansion enclosures between each other.

Two expansion ports on the Controller A are connected to the Ports 1 and 2 on the I/O Module A in the first expansion enclosure in the chain, and the Ports 3 and 4 on the I/O Module A in the first expansion enclosure are connected to the Ports 1 and 2 on the I/O Module A in the adjacent expansion enclosure, and so on.

Two expansion ports on the Controller B are connected to the Ports 1 and 2 on the I/O Module B in the last expansion enclosure in the chain, and the Ports 3 and 4 on the I/O Module B in the expansion enclosure are connected to the Ports 1 and 2 on the I/O Module B in the adjacent expansion enclosure, and so on.

Configuration notes:

• The Relationship and TopSeller models of the ThinkSystem DE240S listed in this section ship with four 1 m SAS cables.
• Four SAS cables are needed per each expansion enclosure (two SAS cables per I/O Module) for connections to the controller enclosure and for daisy chaining of the expansion enclosures.

The ThinkSystem DE Series 2U24 SFF enclosures support up to 24 SFF hot-swap drives. The following tables list supported drive options for the 2U24 SFF controller and expansion enclosures.

The following functions are included with every ThinkSystem DE4000F:

• 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.
• 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 (up to 512 snapshot targets per system).
• Encryption: Provides encryption for data at rest for enhanced data security with the optional FIPS 140-2 Level 2 drives and embedded key management (AES-256) 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.
• 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).

The ThinkSystem DE4000F capabilities can be expanded with the optional synchronous mirroring licensed function. 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).

Note: The synchronous and asynchronous mirroring features of the ThinkSystem DE4000F interoperate with other ThinkSystem DE Series storage arrays.

The following table lists the Feature on Demand (FoD) upgrades for the ThinkSystem DE4000F to enable optional software features. Each optional DE4000F function is licensed on a per-system basis and covers both controller enclosure and all attached expansion enclosures.

Software maintenance is included in the ThinkSystem DE4000F 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 DE4000F supports the following management interfaces:

• ThinkSystem 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, so there is no need for a separate console or plug-in. For more information, see the System Manager Online Help.
• ThinkSystem SAN Manager, a host-installed GUI-based application, for centralized management of multiple storage systems. For more information, see the SAN Manager Online Help.
• ThinkSystem DE Series Storage Plugin for vCenter. For more information, see the DE Series vCenter Plugin Online Help.
• Command line interface (CLI) via SSH or through serial console. For more information, see the CLI Online Help.
• Syslog, SNMP, and e-mail notifications.
• Optional Lenovo XClarity Administrator support for discovery, inventory, and monitoring.

The ThinkSystem DE Series 2U24 SFF enclosures ship with two redundant hot-swap 913 W (100 – 240 V) Platinum AC power supplies, each with an IEC 320-C14 connector. The Relationship models of the ThinkSystem DE4000F 2U24 SFF and DE240S 2U24 SFF enclosures listed in Controller enclosures and Expansion enclosures ship with two 1.5 m, 10A/100-250V, C13 to IEC 320-C14 rack power cables.

The CTO models require the selection of two power cables.
