The following functions are included with every ThinkSystem DS2200:

• Intelligent Real-time Tiering for HDDs: Storage tiering helps optimize storage use with intelligent data placement to improve system performance, reduce costs, and simplify management. The DS2200 automatically and dynamically moves frequently accessed data to higher performing HDDs in the system without manually creating and managing storage tier policies.
• 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.
• Rapid Data Protection Technology (ADAPT): Helps improve performance and availability with significantly faster rebuild time and built-in spare capacity by allowing data to be distributed across all physical drives in the storage pool (drives do not need to be of the same capacity) and sustaining up to two concurrent drive failures.
• RAID levels 1, 5, 6, and 10: Provide the flexibility to choose the level of data protection required.
• Virtualized storage pools: Enables rapid, flexible storage provisioning and simple configuration changes. Stored data is distributed across all drive groups in the pool (wide striping) which helps improve performance, lower latency, and achieve higher volume capacities. When a new drive group is added to the pool, the system performs automatic rebalancing to utilize all drives in the pool for better performance.
• Thin provisioning: Optimizes efficiency by allocating drive storage space in a flexible manner among multiple applications, based on the minimum space required by each application at any given time. With thin provisioning, applications consume only the space they are actually using, not the total space that has been allocated to them, which allows clients to purchase storage they need today and add more as application requirements grow.
• SSD Read Cache: An extension of the controller's cache to improve performance of read-centric workloads
• Rapid RAID Rebuild: Helps significantly decrease the time to recover lost data by only rebuilding the stripe where the corruption occurred, not the empty space or other stripes
• 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.

The ThinkSystem DS2200 capabilities can be expanded with optional licensed functions.

Optional licensed functions include:

• Intelligent Real-time Tiering for SSDs: The SSD tiering upgrade option allows the use of SSDs as read and write storage in the hybrid HDD and SSD storage configurations. Also, this option makes it easy and economical to deploy hybrid storage by dynamically moving frequently accessed data to SSDs in the system, resulting in flash drive performance without manually creating and managing storage tier policies.
• Snapshots upgrade: The snapshot upgrade options increase the supported number of snapshot targets to 512 or 1024 per system.

• Asynchronous Replication: The asynchronous replication feature provides storage system-based data replication between primary (local) and secondary (remote) systems by using asynchronous data transfers over IP (iSCSI) or Fibre Channel communication links. The secondary system can be a replication target for up to four primary systems.

  The replication is performed manually or at predetermined schedule with at least 60 minutes between consecutive runs. For ultimate flexibility, DS2200 asynchronous replication interoperates with the ThinkSystem DS4200 and DS6200, as well as Lenovo Storage S2200 and S3200.

  The asynchronous replication option must be acquired (or licensed) for both primary and secondary systems.

The following table lists the Feature on Demand (FoD) upgrades for the ThinkSystem DS2200 to enable optional software features. Each optional DS2200 function is licensed on a per-system basis and covers both controller enclosure and all attached expansion units.

Configuration notes:

• The SSD Data Tiering Upgrade option is not required for all flash array configurations (a storage system with SSDs only; no HDDs installed) and for hybrid configurations (a storage system with SSDs and HDDs) in which SSDs are used exclusively for SDD read cache; however, it is required for any other hybrid configuration (a storage system with SSDs and HDDs) even when the SSD storage tiering is not used.
• Asynchronous Replication requires an FC/iSCSI Controller-based DS2200 storage unit.

Software maintenance for standard software features is included in the ThinkSystem DS2200 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 services and upgrades for details).

Optional software features include 3-year software maintenance with the ability to extend it up to 5 years in 1-year or 2-year increments with the purchase of the software maintenance extension options that are listed in the following table.

Note: The ThinkSystem DS2200 must have active warranty coverage for the duration of an intended software maintenance extension period.

The ThinkSystem DS2200 supports the following management interfaces:

• Lenovo Storage Management Console (SMC), a web-based interface (WBI) via HTTP, that 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.
• Command line interface (CLI) via Telnet or SSH or through Direct Connect USB.
  Note: Direct Connect USB may require device drivers on the connected computer that uses older Windows operating systems. Drivers are provided on the Lenovo support site, if needed.
• SNMP and e-mail notifications.
• Optional Lenovo XClarity for discovery, inventory, monitoring, alerts, and firmware updates.
