Accelerate your business with all-flash NVMe transformation

The Challenge

Businesses must continually improve the speed and responsiveness of key business operations if they are to reduce time to market and increase customer satisfaction. One key ingredient of this effort is all-flash storage, which greatly accelerates critical workloads.

However, as all-flash becomes prevalent throughout the data center, it soon becomes apparent that enterprise-grade data management capabilities are critical in a shared environment. To deliver the ultimate solution, all-flash storage needs to offer robust data management, integrated data protection, and seamless scalability.

The Solution

To meet enterprise storage requirements, ThinkSystem All-Flash DM Series systems provide high performance, superior flexibility, and best-in-class data management, and includes the industry first full end-to-end NVMe capability. DM Series runs on ONTAP data management software, which gives customers unified storage across block-and-file workloads. It accelerates your business while improving the efficiency, flexibility, and reliability of your IT operations.

This enterprise-class solution accelerates, manages, and protects your business-critical data. Customers who currently do not benefit from all-flash solutions should not be worried about implementing one once they are ready.

ThinkSystem DM Series provides an easy and risk-free transition to all-flash. DM Series systems were purpose-built for flash to deliver industry leading performance, capacity, and density.

Flexible management is also possible through XClarity support. With Lenovo XClarity management software, you can manage your Lenovo ThinkSystem servers, storage and networking together.

Accelerate Your Data

The DM Series all-flash systems are a feature rich and fast storage platform that will beat your expectations of how a storage system should be. They offer superior performance and investment protection and allow you to scale your system up and out as your needs grow. 

When you use the NVMe over Fibre channel protocol you can reduce your latency up to 50%, eliminating the bandwidth bottlenecks inherent in other systems caused by flash storage exceeding the speed of the network.

With Lenovo’s all-flash DM Series systems, you can:

Accelerate the speed of business while increasing operational efficiency:

  • Experience up to 5M IOPS in one cluster using DM Series All-Flash Array systems  

Simplify IT operations while transforming data center economics:

  • All-flash arrays can slash support and performance-tuning costs by up to two-thirds versus hybrid systems
  • Reduce rack space up to 38x and power consumption by 11x with deduplication and compression
  • Guaranteed 3:1 capacity reduction with data reduction technologies
  • Onboard volume encryption, software-based data-at-rest encryption, and multi-factor authentication capabilities

Deploy flash everywhere with maximum flexibility while retaining the control and security of your data:

  • Move data and applications to wherever they run best: on a DM Series system or in the cloud
  • Get the broadest application ecosystem integration for enterprise applications, VDI, database, and server virtualization
  • Integrate flash into your infrastructure nondisruptively, eliminating silos, and scale out as requirements grow

ThinkSystem DM Series All-Flash is ideal for performance-critical applications such as Oracle, Microsoft SQL Server,  VDI, and server virtualization. It is also a great choice for a variety of common data center workloads in shared environments.

ThinkSystem DM Series includes a suite of powerful integrated data-protection software to help protect your competitive advantage. Key benefits include:

  • Deduplication, compression, and compaction paired with cloning and Snapshot copies to reduce storage costs and minimize performance impact
  • Application-consistent backup and recovery to simplify application management
  • Synchronous replication with MetroCluster software ― an industry leading capability for all-flash arrays that delivers zero recovery point objective (possible data loss) and near-zero recovery time objective for mission-critical workloads
  • The ability to meet all of your data compliance and retention requirements via Snaplock.

Optimize Your Data with Flexible Design

The inline data reduction technologies built into DM Series systems typically provide 3x space savings, and the following benefits:

  • Inline data compaction technology uses an innovative approach to place multiple logical data blocks from the same volume into a single 4KB block. It frees up substantial space for database workloads that have relatively small I/O sizes. When combined with inline compression, ONTAP customers have reported space savings as high as 67:1 for an Oracle database.
  • Inline compression has a near-zero performance impact. Detection of incompressible data eliminates wasted cycles.
  • Enhanced inline deduplication maximizes the space savings by eliminating redundant blocks. Some workloads, such as VDI OS patches, can achieve as much as a 70:1 reduction rate.

Whether your performance and capacity needs change or your cloud strategy evolves in the future, your investment is protected:

  • All-flash systems seamlessly cluster with DM Series hybrid systems, enabling you to transparently move workloads between high-performance tiers and low-cost capacity tiers — eliminating any performance silos
  • DM Series enables you to grow and adapt as your business changes. It enables you to intermix different controllers, SSD sizes, and next-generation technologies so your investment is protected. DM Series also provides the industry’s first full end-to-end NVMe solution
  • DM Series has proven cloud connectivity. You can easily move data between the cloud and on premises storage for maximum performance and return on your investment
  • Optimize data management for enterprise workload environments with leading application integration into Oracle, Microsoft, VMware, SAP, and more
