Lenovo ThinkSystem DM7100H

Unified Hybrid Storage Array

Lenovo ThinkSystem DM7100H is a scalable, unified, hybrid storage system that is designed to provide high performance, simplicity, capacity, security, and high availability for large enterprises. Powered by the ONTAP software, Lenovo ThinkSystem DM7100H delivers enterprise-class storage management capabilities with a wide choice of host connectivity options, flexible drive configurations, and enhanced data management features.

Lenovo ThinkSystem DM7100H

The Lenovo ThinkSystem DM7100H 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.

A single Lenovo ThinkSystem DM7100H Storage Array consists of the 4U rack-mount controller enclosure and one or more expansion enclosures. The controller enclosure includes two controllers, 256 GB RAM (128 GB RAM per controller), and 32 GB battery-backed NVRAM (16 GB NVRAM per controller). 25 GbE SFP28 NAS/iSCSI or 4/8/16 Gb Fibre Channel (FC) ports on the controller’s mezzanine cards provide base host connectivity, with adapter card options for additional 1/10 GbE, 25 GbE, or 40/100 GbE NAS/iSCSI, or 8/16/32 Gb FC connections.

The attachment of the Lenovo ThinkSystem DM240S 2U24 SFF, DM120S 2U12 LFF, and DM600S 4U60 LFF Expansion Enclosures to the controller enclosure provides scalability up to 720 drives and flexible drive configurations with the choice of 2.5-inch (SFF) and 3.5-inch (LFF) form factors, 10K rpm SAS and 7.2K rpm NL SAS hard disk drives (HDDs), and SAS solid-state drives (SSDs).

Optimise your data

For an enterprise-class hybrid cloud that offers predictable performance and availability, combine your DM Series storage array with Cloud Volumes ONTAP. This seamlessly integrates with and replicates data to multiple clouds, such as IBM Cloud, Amazon Web Services (AWS), or Microsoft Azure.

FabricPool allows you to tier cold data to the cloud to free up space on expensive and high performing flash media. When using FabricPool you can tier data to Amazon Web Services, Microsoft Azure, Google Cloud, IBM Cloud and Alibaba cloud.


The following features are included with the Lenovo ThinkSystem DM7100H ONTAP software:

  • RAID-4, RAID-DP, and RAID-TEC data protection: Provides the flexibility to choose the level of data protection required and helps improve performance and availability with built-in spare capacity and by distributing data across all physical drives in the aggregate, sustaining to up to one (RAID-4), two (RAID-DP), or three (RAID-TEC) concurrent drive failures.
  • SyncMirror data protection : Adds extra level of data protection and availability by mirroring a pair of RAID aggregates.
  • Flash Cache : Helps accelerate performance of read-centric workloads with read caching on the onboard NVMe flash module.
  • Flash Pool : Helps accelerate performance of read- and write-centric workloads with read and write caching on aggregates with HDDs and SSDs.
  • FlexVol : Provides abstraction layer between the logical volume and its physical location in the storage array.
  • FlexGroup : Enables a single volume to span across multiple clustered storage arrays to maximize storage capacity and automate load distribution.
  • FlexCache : Speeds up access to data and offloads traffic from heavily accessed volumes for read-intensive workloads by placing frequently used data in cache locally or remotely (closer to the point of client access) and serving the data to the clients directly from cache without accessing the data source.
  • Thin provisioning : Optimizes efficiency 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.
  • Compression : Provides transparent inline and post-process data compression to reduce the amount of storage that customers need to purchase and manage.
  • Compaction : Works with compression to pack more data into each storage block to further reduce the amount of storage that customers need to purchase and manage.
  • Deduplication : Performs general-purpose deduplication for removal of redundant data to reduce the amount of storage that customers need to purchase and manage.
  • Snapshots : Enables creation of read-only copies of data for backup, parallel processing, testing, and development, and have the copies available almost immediately.
  • FlexClone :References snapshot metadata to create writable point-in-time copies of a volume.
  • Encryption : Provides software-based encryption for data at rest for enhanced data security with the traditional drives and embedded key management (requires the encryption-capable version of the ONTAP software).
  • Balanced placement : Provides automated workload distribution across the cluster to help increase utilization and performance.
  • Dynamic capacity expansion : Allows the capacity of a volume or aggregate to be expanded by adding new physical drives.
  • Adaptive Quality of Service : Simplifies operations and maintains consistent workload performance by defining QoS policies and automatically adjusting storage resources to respond to workload changes.
  • SnapVault disk-based storage backup : Enables data stored on multiple systems to be backed up to a central, secondary system quickly and efficiently as read-only snapshot copies.
  • SnapRestore : Enables quick recovery of data by reverting a local volume or file to its previous state from a particular snapshot copy stored on the file system.
  • SnapCenter : Provides application- and virtual machine-aware backup and restoration of data by using the Snapshots technology and leverages the SnapMirror capabilities of storage systems to provide onsite or offsite backup set mirroring for disaster recovery.
  • MetroCluster : Provides storage system-based clustering with online, real-time data mirroring between the local and remote sites by using synchronous data transfers over IP or Fibre Channel communication links to deliver continuous availability with zero RPO and near-zero RTO. Note : All storage systems in a MetroCluster configuration must be of the same model.
  • SnapMirror synchronous and asynchronous replication : Provides storage system-based data replication between the storage systems containing source (local) and destination (remote) volumes by using synchronous (as soon as the data is written to the source volume) or asynchronous (at specified regular intervals) data transfers over IP communication links.

Note : The SnapMirror feature of the Lenovo ThinkSystem DM7100H interoperate with other ThinkSystem DM Series storage arrays.
