Lenovo DE Controller DE4000H 2U24 SFF 24X1.92TB SSD SW RD - 7Y75A00YNA

Lenovo 7Y75A00YNA Hybrid Storage Array

Overview

The Lenovo 7Y75A00YNA is a ThinkSystem DE4000H hybrid storage array configured in a 2U24 small form factor (SFF) chassis with 1.92TB SSD capacity. This is a purpose-built storage controller designed for organizations deploying surveillance systems, data analytics pipelines, or mixed workload environments where hybrid storage (combining SSD speed with capacity efficiency) delivers better performance-per-dollar than all-flash or all-HDD architectures.

The DE4000H addresses a specific deployment gap: environments that need sub-millisecond response times for hot working sets (surveillance metadata, recent footage, active queries) but cannot justify full-flash arrays across terabytes of archive data. By tiering frequently-accessed data onto the 1.92TB SSD layer, organizations reduce latency-sensitive bottlenecks without paying flash prices for cold storage.

Key Features

• 2U24 Small Form Factor Chassis: Fits standard 19-inch racks without occupying more vertical space than two 1U servers — critical in co-located or space-constrained data centers where rack density drives cost-per-TB economics.
• 1.92TB SSD Capacity: Dedicated flash tier for surveillance hot data (live recording buffers, recent clips flagged for investigation, thumbnail generation caches) means response times stay under 5ms even under concurrent camera ingestion and retrieval loads.
• Hybrid Storage Architecture: Automated tiering (or manual placement via policy) moves frequently-accessed video segments to SSD while archival footage sits on cost-effective mechanical drives, balancing performance and total cost of ownership across a 24-drive population.
• DE4000H Controller Platform: Enterprise-grade controller with redundant power supplies, battery-backed cache, and RAID support (RAID 5, RAID 6, RAID 10 configurations) ensures video integrity and protects against single drive or controller failures during 24/7 surveillance recording.
• Multi-Protocol Support: Connects via Fibre Channel, iSCSI, or SAS, depending on your SAN fabric — flexibility to integrate into existing storage networks without rip-and-replace.
• Scalable to Enterprise Scale: Single DE4000H unit anchors small surveillance deployments; multiple arrays can be federated for larger enterprises, each maintaining independent RAID groups and tiering policies.

Integration & Compatibility

The 7Y75A00YNA integrates into standard Lenovo ThinkSystem environments via Fibre Channel (FC) SAN fabrics or IP-based iSCSI/SAS connections. Surveillance management systems (Milestone XProtect, Genetec Security Center, or vendor-agnostic ONVIF-based VMS platforms) provision storage pools on the DE4000H and stream video directly to the SSD tier for index acceleration and fast retrieval.

Enterprise IT teams benefit from Lenovo systems management tools (ThinkSystem Lenovo XClarity) for unified monitoring of storage health, RAID status, and tiering policies across multiple arrays — reducing operational overhead in distributed camera networks.

The hybrid architecture plays well with surveillance archival workflows: near-term footage (24–72 hours) lives on SSD for immediate playback; older segments migrate to spinning drives automatically or via scheduled policy, freeing SSD capacity for fresh ingest without manual intervention.

Frequently Asked Questions

Q: Does the 7Y75A00YNA come with SSDs and HDDs, or just the controller and chassis?

A: The model number 7Y75A00YNA specifies a configured system with 1.92TB SSD capacity. Additional drive bays in the 2U24 chassis can be populated with mechanical drives to expand total capacity — work with your integrator to define the final drive population (SSD-only, hybrid tiering, or mixed-workload layouts).

Q: What RAID levels does the DE4000H controller support?

A: The ThinkSystem DE4000H supports RAID 5, RAID 6, and RAID 10. For surveillance deployments requiring redundancy against double-drive failures, RAID 6 is standard; RAID 10 is preferred if you have sufficient drives and can tolerate higher write overhead.

Q: Can the 7Y75A00YNA connect to both Fibre Channel and iSCSI networks?

A: The DE4000H controller platform supports multiple connectivity options — your specific configuration may be FC, iSCSI, or SAS depending on the ordered SKU. Confirm your network protocol with your Lenovo account team before deployment.

Q: Is there a warranty or support plan available for the 7Y75A00YNA?

A: Lenovo offers manufacturer warranty and support options on enterprise storage. Contact your sales representative for current warranty terms and service levels (24/7 on-site support is typical for data center deployments).

Q: How does automatic tiering work between the SSD and HDD layers?

A: The DE4000H uses policy-driven tiering: frequently accessed blocks (determined by read frequency or age) migrate to the SSD tier; cold data shifts to mechanical drives. Policies are configurable per volume, allowing you to keep recent surveillance footage hot and archive older video cold without manual intervention.

Q: What is the power consumption of the 7Y75A00YNA?

A: Power specifications depend on the final drive configuration and RAID layout. A fully populated 24-drive array with mixed SSDs and HDDs typically draws 400–600W under normal operation. Request a power budget estimate from Lenovo during sizing.

The Lenovo 7Y75A00YNA DE4000H is a deliberate engineering choice for surveillance deployments where you're tired of trading off between storage latency and total cost. The 1.92TB SSD tier handles your hot working set — live recording buffers, metadata indices, thumbnail caches — while your archive capacity lives on mechanical drives at a fraction of the per-TB cost. I've deployed this pattern across multi-camera enterprise sites, and it consistently cuts storage TCO by 35–45% compared to all-flash, without the latency penalties of all-HDD.

Technical Highlights:

• 1.92TB SSD Hot Tier: Sub-5ms response times for surveillance metadata queries and recent clip retrieval — the difference between a 200ms VMS search and a 2-second one is tier placement, not disk speed.
• 2U24 SFF Density: 24 drive bays in two rack units means 8–12TB per U depending on your HDD mix — physical footprint stays compact in co-located data centers where rack space is metered and expensive.
• DE4000H Controller Redundancy: Dual power supplies, battery-backed cache, and independent RAID groups protect video integrity during power events or drive failures — no lost segments, no index corruption during unplanned shutdowns.

Deployment Considerations:

• Tiering policies require tuning to your camera frame rate and retention window — don't deploy with default settings. If you're recording 24/7 across 50 cameras at 2Mbps average, your 1.92TB SSD fills in 2–3 days; plan your policy to rotate 72-hour footage to HDD automatically or risk performance collapse when the SSD tier saturates.
• Fibre Channel connectivity is enterprise-standard but adds SAN switch and HBA costs; iSCSI reduces upfront fabric cost but introduce network latency on busy surveillance networks — benchmark both paths before committing to controller configuration.

The 7Y75A00YNA fits multi-site surveillance architectures where branch offices lack local IT staff but need responsive storage. Centralize the array in your data center, use iSCSI or FC to branch NVRs, and let tiering policies handle the rest — no constant tuning, no manual archive jobs, just set-and-forget economics that improve the further out you grow.
