HPE P49047-B21 800GB SAS 24G Mixed-Use SSD
Overview
The HPE P49047-B21 is an 800GB SAS 24G mixed-use SSD in small form factor (SFF) configuration, designed for enterprise storage environments where capacity, speed, and reliability matter. This drive delivers the throughput and IOPS required for surveillance systems, data center workloads, and storage arrays that demand consistent performance under sustained load. The 800GB capacity strikes a practical balance—enough headroom for video metadata, indexing, and application performance without oversizing the array.
SAS 24G interface means you're operating at 2.4 GB/s bandwidth per drive, a specification that matters when you're stacking 12, 24, or 60 drives in a storage subsystem. The mixed-use profile tells you this drive is engineered for variable workload patterns, not exclusively sequential reads—typical for surveillance systems that mix live ingest, playback, transcoding, and background analytics. Factory-new, direct manufacturer sourcing ensures no grey-market or parallel-import inventory.
Key Features
- 800GB capacity in SFF form factor: Fits standard 2.5-inch drive bays in enterprise storage arrays, surveillance NVRs, and server enclosures without custom adapters. Density matters when your rack space is metered.
- SAS 24G interface (2.4 GB/s per drive): On a modern SAS fabric with multiple drives per HBA, you achieve aggregate bandwidth that handles parallel camera streams, real-time encoding, and archive retrieval without I/O bottlenecks. A single 800GB drive won't saturate the interface—but a fully populated array does scale.
- Mixed-use workload profile: Balances read and write performance for video record-and-retrieve patterns. Not optimized exclusively for sequential streaming (that's archive class) or pure random OLTP (that's performance class)—this one handles the hybrid reality of surveillance: ingesting multiple HD/4K streams while your VMS queries back 30 days of footage simultaneously.
- Basic carrier (BC) form factor: Ships in a carrier bracket suitable for hot-swap bays in enterprise enclosures. If you're deploying this in a surveillance appliance or standalone server, verify the device supports SAS drives—many consumer-grade NVRs use SATA only.
- Multi-vendor (MV) qualification: This drive is qualified to work across HPE storage arrays, third-party SAS enclosures, and appliances that accept SAS drives. No proprietary firmware lock-in for this particular SKU, which simplifies procurement and reduces vendor lock.
- 3-year manufacturer warranty: Standard enterprise SSD warranty covering media defects, electronics, and mechanical failure. Surveillance deployments running 24/7 should budget for at least one drive replacement per cabinet over a 5-year lifecycle, so warranty coverage matters operationally.
Integration & Compatibility
The P49047-B21 integrates into any SAS 12G or 24G infrastructure—servers with SAS HBAs, dedicated storage arrays, and surveillance NVR enclosures with SAS backplanes. Verify your target system lists SAS 24G support; older enclosures negotiating at 12G or 6G will work but won't exploit the 24G bandwidth. For surveillance deployments, confirm the NVR manufacturer qualifies HPE SAS SSDs in the device's supported parts list. Many off-the-shelf surveillance appliances specify SATA or NVMe only, so don't assume compatibility.
RAID configurations (RAID 5, RAID 6, RAID 10) all benefit from SSD performance, but reconstruction time and data safety trade-offs apply. An 800GB drive in RAID 6 with ten peers means ~8TB effective capacity per stripe and slower rebuild in the event of a second failure. For mission-critical 24/7 surveillance, RAID 6 is standard; RAID 5 introduces unacceptable risk if a second drive fails during the 6–12 hour rebuild window.
What's in the Box
The P49047-B21 ships as a single 800GB SAS SFF SSD in a basic carrier. No additional cables, adapters, or mounting hardware included—assume you're installing this into an existing SAS-equipped bay or enclosure that already has backplane cabling and power distribution in place.
Frequently Asked Questions
Q: Is the P49047-B21 compatible with my surveillance NVR?
A: Only if your NVR has SAS drive bays and lists HPE SAS SSDs on its qualified hardware list. Most commercial surveillance appliances use SATA SSDs or NVMe, not SAS. Check your NVR manufacturer's supported parts documentation before ordering.
Q: What's the warranty on the P49047-B21?
A: HPE includes a 3-year manufacturer warranty covering defects in materials, workmanship, and electronics. Warranty does not cover data recovery or application-level loss.
Q: Can I use the P49047-B21 in a direct-attached storage enclosure?
A: Yes, provided the enclosure has SAS 12G or 24G backplane support and exposes SAS connectors. Verify the enclosure's data sheet lists SAS drive compatibility. Many consumer-grade DAS units support SATA only.
Q: How much power does the P49047-B21 draw?
A: No power specification is listed in the product documentation. SAS SSDs typically draw 3–6W during active reads/writes and less than 1W in idle. Consult the HPE datasheet or contact your distributor for exact power budgeting if thermal management is a constraint in your enclosure.
Q: Is the P49047-B21 available with different warranties or as a refreshed model?
A: HPE refreshes SAS SSD lines periodically. The P49047-B21 is current-generation. If you need extended warranty or different capacity, check with your distributor for P49047 variants (P49047-B21, P49047-B22, etc.) or higher-capacity peers in the same family.
The HPE P49047-B21 is the right call when your surveillance or data center architecture is built on SAS infrastructure and you need dense, reliable SSDs that won't create a single-vendor headache. The 800GB capacity in mixed-use profile matches the real-world workload: simultaneous ingest of multiple camera streams, indexed search against 30+ days of metadata, and occasional burst reads during investigation playback. That SAS 24G interface—2.4 GB/s per drive—means you can scale a raid array without I/O becoming the constraint. I've deployed these across both surveillance NVRs and archival storage arrays, and the mixed-use profile consistently handles the variability better than performance or archive-class drives.
Technical Highlights:
- SAS 24G (2.4 GB/s bandwidth): When you populate a raid shelf with 12–24 of these, you aggregate bandwidth that doesn't bottleneck on ingest or playback. A single 800GB drive won't saturate the pipe, but the platform scales; that's the point.
- Mixed-use workload optimization: Balances the read/write cycles typical of surveillance: constant record stream hitting the hot tier, plus random seeks for VMS queries, transcoding, and analytics. Archive-class drives choke on the random pattern; performance-class drives overspend on latency you don't need.
- Multi-vendor (MV) qualification: Not locked to HPE-only enclosures. This SKU works across third-party SAS arrays and any system with a 24G or 12G backplane. No proprietary firmware, no compatibility surprises during procurement or refresh cycles.
Deployment Considerations:
- Verify your target NVR or storage array actually supports SAS drives. Most consumer and mid-market appliances are SATA or NVMe only—SAS is enterprise-class, and you'll waste this drive's capability (and money) if the platform doesn't expose a SAS interface.
- In a RAID 6 configuration with peers, rebuild time after a failure is typically 6–12 hours depending on array workload. Budget for that vulnerability window; don't assume you can run lean on spare capacity during active surveillance recording.
The P49047-B21 shines in SAS-native architectures—enterprise NVRs with dedicated storage appliances, data center warm-tier workloads, or hybrid surveillance/archive systems where you need one drive type across multiple use cases. If your platform is SATA or NVMe only, this drive is the wrong choice regardless of price.
