Description:

The Lenovo ThinkSystem DE4000H is a 2U hybrid SAN array that supports both SSDs and HDDs, delivering enterprise reliability and scalability.

This configuration uses the 2U24 SFF enclosure populated with 24 × 3.84 TB 12 Gb/s SAS SSDs, equating to nearly 92 TB of raw flash storage—spanning 16 SAN modules.

With dual controllers and 64 GB total controller memory, the system enables accelerated performance, ideal for I/O-intensive workloads like virtualization, analytics, and VDI environments .

The DE4000H supports block-level connectivity over 1/10 Gb iSCSI or 4/8/16 Gb Fibre Channel, plus 12 Gb SAS.

It offers dynamic disk pools™, hot-swappable power supplies, redundant I/O modules, and expansion support via DE240S and DE120S enclosures—scaling up to 120 SSDs and 192 drives system-wide.

Key Features:

  • ✅ 2U24 SFF hybrid storage chassis with 24 hot-swappable 2.5″ drive bays (SSDs/HDDs) 
  • ✅ 24 × 3.84 TB 12 Gb/s SAS SSDs—packed into 16 modules (1DWD or FIPS as needed) 
  • ✅ Dual active-active controllers with 32 GB controller memory each (64 GB total) 
  • ✅ Host interfaces: 1/10 Gb iSCSI or 4/8/16 Gb FC, plus 12 Gb SAS backend 
  • ✅ Dynamic Disk Pools™ RAID for optimal rebuild performance and data resilience 
  • ✅ Hot-swappable redundant PSUs and I/O modules for high availability
