HPE 15.3TB NVME RI E3S EC1 CM7 SSD - P61187-B21

HPE P61187-B21 15.36TB NVMe Gen5 E3.S Read-Intensive SSD

Overview

The HPE P61187-B21 is a 15.36TB NVMe Gen5 solid-state drive in the E3.S form factor, purpose-built for read-intensive surveillance and archival workloads. This drive delivers the capacity density your surveillance infrastructure needs without sacrificing performance or reliability. The P61187-B21 (often searched as P61187 B21) supports next-generation NVMe Gen5 interface speeds while maintaining a 3-year manufacturer warranty, making it a practical choice for large-scale video storage deployments where capacity and sustained throughput matter more than peak performance.

Key Features

• 15.36TB Capacity: Eliminates the need for multiple smaller drives in surveillance-grade storage arrays. A single P61187-B21 holds approximately 1,500–2,000 hours of compressed HD video (depending on bitrate), reducing the number of drive slots consumed and lowering rack space requirements in multi-camera deployments.
• NVMe Gen5 Interface: Delivers up to 128 Gb/s theoretical bandwidth, enabling high-speed data transfer when reading recorded footage or backing up surveillance streams. Practical benefit: faster evidence recovery and reduced latency during multi-stream playback on security workstations.
• E3.S Form Factor: Designed for enterprise storage systems and purpose-built surveillance appliances. The E3.S (Enterprise 3.5-inch Small Form Factor) footprint fits directly into standard 2U/4U rackmount enclosures without adapters, simplifying installation and hot-swap drive replacement.
• Read-Intensive Profile: Optimized for sustained read operations typical of surveillance retrieval, evidence export, and continuous archival access. Write endurance is lower than mixed-use drives, which is acceptable for surveillance scenarios where footage is written once and read many times over weeks or months.
• 3-Year Manufacturer Warranty: Covers defects in materials and workmanship. In a 24/7 surveillance context, this warranty provides confidence in long-term reliability without immediate replacement cost if a drive fails within the warranty period.
• Enterprise-Grade Reliability: Built to HPE's qualification standards for data center and surveillance environments. Meets SMART monitoring and predictive failure detection, integrating with most enterprise storage platforms' health dashboards to alert you before catastrophic failure.

Integration & Compatibility

The HPE P61187-B21 is compatible with any enterprise storage system, NVR, or archival appliance that supports NVMe Gen5 drives in E3.S form factor. Common integration points include:

• Enterprise NVRs and SAN arrays: Direct installation into NVMe bays (no adapters needed) in storage enclosures from Milestone, Genetec, Axis, and other manufacturer appliances that feature native E3.S slots.
• Hyperconverged surveillance infrastructure: Use alongside compute nodes in distributed surveillance platforms, where the high capacity and Gen5 speed reduce network congestion during evidence retrieval or multi-site archival sync.
• Backup and retention tiers: Deploy in secondary or tertiary storage for long-term retention (30-90 day archives) where read frequency is lower but capacity density is critical to cost control.

Verify your storage appliance's NVMe bay specifications and firmware support for Gen5 drives before ordering; some legacy systems may require firmware updates or be limited to Gen3/Gen4 support.

What's in the Box

The HPE P61187-B21 arrives as a single factory-sealed drive with standard ESD protective packaging and no additional accessory hardware included. Installation into an enterprise enclosure typically requires no additional components beyond the drive itself.

Frequently Asked Questions

Q: What is the warranty duration on the P61187-B21?

A: The HPE P61187-B21 includes a 3-year manufacturer warranty covering defects in materials and workmanship.

Q: Is the P61187-B21 suitable for write-heavy surveillance applications?

A: No. The P61187-B21 is optimized for read-intensive workloads (retrieval, archival, playback). If your surveillance system requires frequent multi-stream simultaneous write operations at very high bitrates, consider a mixed-use or write-optimized NVMe variant instead.

Q: What is the storage capacity of the P61187-B21?

A: The P61187-B21 provides 15.36TB of usable storage capacity, offering significant density for multi-month or multi-year retention tiers in large surveillance deployments.

Q: Does the P61187-B21 require any special installation hardware or adapters?

A: No. The E3.S form factor mounts directly into enterprise enclosures and storage systems with native E3.S slots. No bridge cards or adapters are needed. Always verify your appliance supports NVMe Gen5 and E3.S before purchasing.

Q: Can I use the P61187-B21 in surveillance systems with older storage enclosures?

A: Only if your enclosure has E3.S NVMe bays and supports NVMe Gen5. Legacy systems with Gen3 or Gen4 slots will not recognize this drive. Check your storage system's technical specifications and firmware version before ordering.

The HPE P61187-B21 is a purpose-fit storage component for surveillance deployments at scale. At 15.36TB capacity in a single E3.S form factor, this drive eliminates the physical footprint penalty of older, lower-capacity modules—critical when you're managing retention across multiple camera sites or consolidating evidence archives into a central NVR appliance. The Gen5 NVMe interface ensures that when you're pulling evidence for export or running forensic queries across months of footage, you're not bottlenecked by drive throughput.

Technical Highlights:

• 15.36TB capacity in E3.S form factor: Delivers roughly 1,500–2,000 hours of compressed HD surveillance per drive, depending on codec and bitrate. In a 4U storage enclosure with 8 bays, you're looking at petabyte-scale capacity in a single unit—far denser than traditional 2.5-inch SSD approaches.
• NVMe Gen5 (128 Gb/s): Supports concurrent reads from multiple simultaneous playback streams without introducing latency. When forensic reviewers are pulling clips from multiple camera zones simultaneously, sustained read performance is what prevents timeouts and sluggish UI response in your VMS.
• Read-intensive optimization: Write endurance is lower than mixed-use drives, but surveillance workloads are naturally read-biased (record once, retrieve many times). This trade-off significantly reduces cost-per-terabyte compared to enterprise mixed-use alternatives.

Deployment Considerations:

• Verify your storage appliance or NVR explicitly supports E3.S NVMe Gen5 drives. Legacy systems with Gen3/Gen4 NVMe slots or 2.5-inch SSD bays will not recognize this drive. Firmware updates may be required on newer appliances.
• Read-intensive profile means this drive is not suitable for write-heavy real-time analytics platforms or distributed edge nodes with high concurrent write load. If your system demands sustained multi-stream writes at high bitrate, specify a mixed-use or write-optimized variant.

The P61187-B21 is the right choice for centralized NVR storage, long-term evidence tiers, and multi-site surveillance consolidation where capacity density and evidence retrieval speed matter more than peak write performance. Pair it with enterprise enclosures supporting hot-swap NVMe and SMART monitoring for a reliable, scalable surveillance archive.
