The Challenge

It’s essential that business-critical applications run with maximum efficiency. Data centers are looking for ways to improve the speed and responsiveness of the applications that control their mission-critical business operations.

One way to differentiate your organization from the competition and accelerate time-to-market is to extract value and insights quickly and reliably from a range of mixed workload environments.

The Solution

The DE6600F offers extreme performance with up to 2M IOPs and 44GBps throughput. This all-flash 2U storage arrays supports 24 NVMe SSDs in the controller enclosure, providing industry leading performance for enterprise workloads, such as Big Data analytics, artificial intelligence, and databases.

The DE6400F provides performance and scale in a 2U design. With support for 24 NVMe SSD drives in the controller enclosure, this all-flash storage array is ideal for enterprise workloads and offers up to 20GBps read bandwidth and up to 670k IOPs and sub-100 microsecond response times.

The compact 2U Lenovo ThinkSystem DE6000F all-flash (SSD) mid-range storage array will accelerate access to your data.

This all-flash array combines industry-leading, enterprise-proven availability features with up to 1M of IOPS, sub-100 microsecond response times, and up to 21GBps of read bandwidth.

Similarly, the entry-level Lenovo ThinkSystem DE4000F all-flash storage system boosts access to your data for greater value in only 2U.

It also combines enterprise-proven availability features with affordable IOPS, sub-100 microsecond response times, and up to 10GBps of read bandwidth.

The ThinkSystem All-Flash array availability features include:

  • Redundant components with automated failover
  • Intuitive storage management with comprehensive tuning functions
  • Snapshot copy creation and volume copy
  • Asynchronous mirroring for data protection (DE6000F and DE4000F only)
  • Data assurance for data integrity and protection against silent data corruption

Both storage subsystems optimize price/performance, configuration flexibility, and simplicity. They enable you to process your critical business data faster and with better insights, for more effective decision-making.

All-Flash Delivers Performance

The DE All-Flash Series delivers the performance of more than 2,000 15k rpm HDDs, yet requires only 2% of the rack space, power, and cooling.

Because it consumes 98% less space and power, DE Series can significantly improve the overall efficiency of your IT operations while continuing to meet your performance requirements.

Protecting Your Competitive Advantage

Dynamic drive pool (DDP) technology allows storage administrators to simplify RAID management, improve data protection, and maintain predictable performance under all conditions.

This innovative technology minimizes the performance impact of a drive failure and can return the system to optimal condition up to eight times faster than with traditional RAID.

With shorter rebuild times and patented technology to prioritize reconstruction, DDP capabilities significantly reduce exposure to multiple disk failures, offering a level of data protection that cannot be achieved with traditional RAID.

With DE Series, all management tasks can be performed while the storage remains online with complete read/write data access. Storage administrators can make configuration changes, conduct maintenance, or expand the storage capacity without disrupting I/O to attached hosts.

DE Series nondisruptive administration features include:

  • Dynamic capacity and volume expansion
  • Dynamic segment size migration
  • Dynamic RAID-level migration
  • Non-disruptive firmware updates

DE Series all-flash arrays protect against data loss and downtime events, both locally and remotely, using advanced data protection features, including:

  • Snapshot / Volume copy
  • Asynchronous mirroring (DE6000F and DE4000F only)
  • Synchronous mirroring (DE6000F and DE4000F only)
  • Full drive encryption

Eventually, all drives get redeployed, retired, or serviced. When this happens, you do not want your sensitive data going out the door with them. Combining local key management with drive-level encryption gives you comprehensive security for data-at-rest with no impact to performance.
