The Challenge

Enabling the data-driven business across flash, disk, and cloud

Storage has evolved from an IT afterthought to a crucial component within a company’s infrastructure. Businesses are feeling the pressure to keep up with the explosive data growth. Standard hard disks are no longer an acceptable medium to keep up with the always-adapting needs a company has when it comes to storage.

Shrinking budgets, overextended staff, and the never-ending growth of data that must be stored and accessed efficiently dictate the need for a new approach.

You still must consider storage uptime, scalability, and cost efficiency, but now you also need to take advantage of flash acceleration, cloud integration, unified support for SAN and NAS, and simplified data mining for competitive advantage.

For those data centers hampered by structural limitations in legacy storage and data architectures, this can be problematic. Traditional storage arrays tend to consist of isolated data silos and cannot meet today’s service-level requirements or easily leverage public or private clouds.

The Solution

Unified scale-out hybrid storage with best-in-class data management

A new approach to storage is needed that combines high-performance hardware and adaptive, scalable storage software into an integrated solution. It must support current workloads, yet also take advantage of the new applications and evolving IT models.

DM Series Hybrid systems support a broad range of unified workloads and can seamlessly scale performance and capacity, simplifying the task of managing growth and complexity. This flexibility enables you to place your data in the precise storage environment that delivers the ideal combination of performance, capacity, and cost-effectiveness so you can keep up with changing business needs while meeting your core IT requirements.

For growing organizations that are concerned about budgets and meeting challenging IT needs, Lenovo ThinkSystem DM Series Hybrid systems are the perfect choice.

Scale and adapt to meet changing needs

Expand from a base of two nodes to a 6-array cluster containing up to 13.8PB (SAN) or a 12-array cluster containing up to 27.6PB(NAS).For flexible development as required by your organization, you can cluster DM Series all-flash models.

Adding and replacing storage systems and components is non-disruptive. This enables you to perform updates while running your usual workloads, without having to worry about maintenance windows.

Extreme availability, non-disruptive operations

Lenovo ThinkSystem DM Series arrays are designed to meet high availability requirements for mission critical operations. Through redundant hardware design and advanced software availability features, including snapshotting, replication, , and advanced ransomware protection, ThinkSystem DM Series can be implemented to deliver high application availability. Software and firmware updates, hardware repair and replacement, and load balancing are performed in real-time, with no need for planned downtime. Integrated data protection technologies protect your data, accelerate recovery, and integrate with leading backup applications for easier management.

MetroCluster expands your data protection to eliminate the risk of data loss by synchronously mirroring data between locations for nonstop availability of information. You can configure a MetroCluster storage array to mirror data within a single data center, or between two different locations up to 700 km away.

Reduce your TCO and improve your ROI with technologies such as deduplication, compression, compaction, thin provisioning, and space-efficient snapshot copies — all leading to a lower cost per effective gigabyte of storage.

Optimize hybrid cloud deployment

Many organizations today use cloud IT models as a service-oriented IT architecture to enhance return on investment and assets. For this reason, we optimized DM Series hybrid arrays running for private and hybrid cloud with secure multitenancy, quality of service (QoS), nondisruptive operations, and easily defined tiers of service.
