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 for hybrid cloud environments.

The Solution

To meet enterprise storage requirements, ThinkSystem All-Flash DM Series systems provide high performance, superior flexibility, best-in-class data management, and includes the industry first full end-to-end NVMe capabilities.

DM Series data management software gives customers unified storage across block, file, and object 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 should now consider all-flash solutions because they simplify data management at the same or better cost as traditional HDD-based arrays.

ThinkSystem DM Series provides an easy and risk-free transition to all-flash. Customers can seamlessly cluster DM Series hybrid and flash as well as multi-generational systems together to ensure absolute investment protection. DM Series systems were purpose-built for flash to deliver industry leading performance, capacity, and density.

Simplified Monitoring and Management

ThinkSystem Intelligent Monitoring is an intelligent and intuitive digital advisor which uses AI and predictive analytics to provide imperative insights, proactive care and optimization, and customized dashboards enabling users to manage multiple DM and DE Series systems in a single web-accessible platform. Preemptive system information and alerts will expose risk factors and prevent problems before they affect your business and cut down on support costs and engagements. Intelligent capacity and performance monitoring will allow you to stay ahead of the curve and plan accordingly to meet your business’s growth needs.

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
  • Reduce latency by 50% when using end to end NVMe over FC infrastructure
  • Leverage Ethernet infrastructure to reduce latency and lower TCO with NVMe over TCP
  • Tier cold data off your SSDs to lower cost object storage to optimize your flash performance

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
  • ThinkSystem Intelligent Monitoring that uses AI and predictive analytics to provide essential insights, prescriptive guidance, and proactive support to simplify your support experience and optimize your Lenovo Storage Environments.

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 non-disruptively, 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:

  • Automatic ransomware protection against cyberattacks with preemptive detection and enhanced recovery, based on machine learning.
  • 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
  • Flexibility and efficiency to support backup, data distribution, and disaster recovery with SnapMirror replication, including cloud-native S3 backup.
  • Zero data loss and transparent application failover with SnapMirror Business Continuity leveraging simple administration and platform flexibility to retain high performance and business resiliency.
  • 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 workload
  • 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 will 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, 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:

  • DM Series has proven cloud connectivity. Easily tier data between the cloud and on-premises storage for maximum performance and return on your investment.
  • Replicate your critical data to the cloud using Cloud Volumes, enhancing: data protection, security, and compliance.
  • Data can be tiered or replicated to multiple cloud vendors, ensuring the best value and cloud features with no vendor lock-in.
  • 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.
