Introduction

Lenovo ThinkSystem DM7000F is a scalable, unified, all flash storage system that is designed to provide high performance, simplicity, capacity, security, and high availability for large enterprises. Powered by the ONTAP software, ThinkSystem DM7000F delivers enterprise-class storage management capabilities with a wide choice of host connectivity options, flexible drive configurations, and enhanced data management features, including support for NVMe over Fabrics. The ThinkSystem DM7000F is a perfect fit for a wide range of enterprise workloads, including big data and analytics, artificial intelligence, engineering and design, hybrid clouds, and other storage I/O-intensive applications.

ThinkSystem DM7000F models are 3U rack-mount controller enclosures that include two controllers, and 256 GB RAM and 16 GB battery-backed NVRAM (128 GB RAM and 8 GB NVRAM per controller). Universal 1/10 GbE NAS/iSCSI or 4/8/16 Gb Fibre Channel (FC) ports and 1/10 GbE RJ-45 ports provide base host connectivity, with an option for additional 1/10 GbE, 25 GbE, or 40 GbE NAS/iSCSI, or 8/16/32 Gb FC connections with the adapter cards.

A single ThinkSystem DM7000F Storage Array scales up to 384 SFF solid-state drives (SSDs) with the attachment of Lenovo ThinkSystem DM240S 2U24 SFF Expansion Enclosures.



Up to 12 DM7000F Storage Arrays can be combined into a clustered system in a NAS environment, or up to 6 DM7000F Storage Arrays can be combined into a clustered system in a SAN environment.

Did you know?

A single ThinkSystem DM7000F scales up to 5.89 PB of raw storage capacity. A cluster of the DM7000F storage systems scales up to 70.7 PB for NAS or up to 35.3 PB for SAN environments.
The ThinkSystem DM7000F offers unified file and block storage connectivity with support for 1 GbE, 10 GbE, 25 GbE, and 40 GbE NAS and iSCSI, and 8 Gb, 16 Gb, and 32 Gb Fibre Channel protocols at the same time.

Key features

The ThinkSystem DM7000F offers the following key features and benefits:

• All-flash array capabilities to meet 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.
• Scalable, all flash storage with dual active/active controller configurations for high availability and performance.
• NVMe over Fabrics helps achieve up to two times higher performance at a half of the latency.
• Improved performance and data protection with RAID-DP and RAID-TEC, as well as support for traditional RAID 4.
• Flexible host connectivity to match diverse client needs with support for unified NAS and SAN storage protocols, including 1/10 GbE, 25 GbE, and 40 GbE NAS and iSCSI, and 8/16/32 Gb Fibre Channel.
• 12 Gb SAS drive-side connectivity with multipathing with up to 24x 2.5-inch small form factor (SFF) drives in the 2U24 SFF expansion enclosures.
• Scalability to up to 384 SFF drives with the attachment of the ThinkSystem DM240S 2U24 SFF expansion enclosures to satisfy growing needs for storage capacity and performance.
• Rich set of standard storage management functions available at no extra cost, including snapshots, volume copy, quality of service, thin provisioning, compression, deduplication, encryption, disk-based backup, application- and virtual machine-aware backup, quick data recovery, clustering, synchronous replication, and asynchronous replication.
• Optional WORM (write once, read many) (SnapLock) licensed function to reinforce permanence and integrity of stored data and to ensure compliance with applicable regulations.
• Scale-out clustering of up to 12 ThinkSystem DM Series storage systems for NAS connectivity or up to six DM Series storage systems for SAN connectivity.
• Intuitive, web-based GUI for easy system setup and management.
• Lenovo XClarity support for centralized systems management of Lenovo x86 servers, switches, and storage, which provides automated agent-less discovery, inventory, monitoring, and additional platform-specific functions across multiple systems.
• Designed for 99.9999% availability with redundant hot-swap components, including controllers and I/O modules, power supplies, and non-disruptive firmware upgrades.
• Certified Enterprise Storage for SAP HANA Tailored Data center Integration (TDI).
• Certified storage for Oracle VM.
• Certified storage for Citrix XenServer: http://hcl.xenserver.org/storage/910/Lenovo_DM_Series.

The ThinkSystem DM7000F supports attachment of up to 16 ThinkSystem DM240S 2U24 SFF expansion enclosures. The expansion enclosures support 2.5-inch capacity-optimized (1 drive write per day [DWD]) 960 GB, 3.84 TB, 7.68 TB, and 15.36 TB SAS hot-swap SSDs. More drives and expansion enclosures are designed to be dynamically added with virtually no downtime, which helps to quickly and seamlessly respond to ever-growing capacity demands.
The ThinkSystem DM7000F offers high levels of system and data availability with the following technologies:

• Dual-active controllers (high availability pair) with automatic load balancing and failover
• Mirrored, battery-backed controller NVRAM 
• Dual-port SAS SSDs with automatic drive failure detection and rebuild
• Redundant, hot-swappable and customer replaceable hardware components, including SFP+/QSFP+ transceivers, controller and I/O modules, power supplies, and drives
• Automated failover for the data path between the host and the drives with multipathing
• Non-disruptive controller and drive firmware upgrades
• Scale-out clustering
