Lenovo ThinkSystem DE4800H HICless Hybrid Flash Array 2U24 - SAN - SAS1

For data centers that demand high throughput and adaptive capacity, the Lenovo ThinkSystem DE4800H Hybrid Flash Array 2U24 SAN Storage System delivers a dual-controller architecture with 64GB of total cache and support for up to 1.8PB of raw storage. This 2U rackmount unit houses 24 small form factor drive bays and can scale to 192 drives with expansion enclosures, making it a flexible foundation for mixed workloads.

Highlights

• Hybrid flash array with 24 SFF drive bays (2.5-inch) for SAS SSDs and HDDs
• Dual active/active controllers with 32GB cache per controller (64GB total)
• Supports 12Gb SAS host connectivity, with options for 16/32Gb Fibre Channel and 10/25Gb iSCSI
• Scalable up to 1.8PB raw capacity with DE120S, DE240S, or DE600S expansion enclosures
• Comprehensive data services: thin provisioning, snapshots, volume copy, remote replication, dynamic tiering, SSD cache, and data assurance
• Redundant hot-swappable power supplies and non-disruptive upgrades for high availability

In daily use

The DE4800H is engineered for environments where performance and reliability are non-negotiable. Its dual controllers ensure continuous operation, while the ThinkSystem Storage OS provides an intuitive web-based management interface. Administrators can leverage ADAPT dynamic disk pools alongside traditional RAID levels (0, 1, 3, 5, 6, 10) to balance performance, capacity, and protection. The hybrid design allows intelligent tiering between flash and spinning media, optimizing cost per IOPS without sacrificing latency-sensitive applications.
