Key technical characteristics and what they mean for your environment

Capacity and form factor

With a usable capacity of 400 gigabytes, the HPE 849937-001 is positioned as a mid-capacity enterprise SSD that fits the 3.5-inch LFF bay standard. The choice of a 3.5" form factor allows organizations that already have large form factor enclosures—like the D6020—to populate densified drive drawers with fewer, higher-end SSDs without redesigning the chassis or caddies. The 400GB density is especially useful for applications that require predictable, fast IOPS rather than large single-disk capacity, and it pairs well with tiered storage architectures where high-performance SSDs sit in front of higher-capacity HDD tiers. :contentReference[oaicite:1]{index=1}

Interface and transfer rate

The drive uses a 12Gb/s Serial Attached SCSI (SAS) interface, delivering higher link bandwidth than legacy 6Gb/s SATA channels and enabling better multi-queue performance and lower command latency in heavily loaded systems. 12Gb/s SAS is the enterprise standard for modern HPE disk enclosures and Smart Array controllers, allowing the SSD to reach its designed sequential and random throughput when paired with compatible controllers. This makes the drive a natural choice for HPE-certified enclosures and controllers which advertise 12Gb/s connectivity. :contentReference[oaicite:2]{index=2}

Drive class: Mixed-Use (MU)

The Mixed-Use (MU) classification indicates that the drive’s flash media and firmware are tuned for a balanced mix of read and write activity. MU SSDs are engineered to sustain higher write workloads than read-intensive drives while offering higher endurance than consumer or workload-specific parts. This makes MU drives ideal for virtual machines, database logging, and other transactional workloads where both reads and writes are frequent but not constant full-drive write saturation. Enterprise MU drives typically include advanced wear-leveling, power-loss protection and robust error correction to meet 24/7 data center reliability expectations. :contentReference[oaicite:3]{index=3}

Compatibility and enclosure integration

Designed for HPE D6020 enclosures

The part is widely referenced in compatibility lists and resellers as intended for use in HPE D6020 12Gb/s SAS disk enclosures. The D6020 is a 5U storage enclosure that supports hot-plug LFF drives in pull-out drawers and is commonly used to extend storage capacity for ProLiant rack and blade servers. Because the D6020 was designed for 12Gb/s SAS, the 849937-001’s interface and form factor allow plug-and-play installation, predictable performance scaling as drives are added, and support for cascading multiple D6020 enclosures behind appropriate Smart Array host bus adapters. For deployments using the D6020, the drive’s certification and part-number references simplify procurement and inventory management. :contentReference[oaicite:4]{index=4}

Server and controller support

When planning an installation, check compatibility with HPE Smart Array controllers and server platforms. The MU-class drive is intended to interoperably work with a wide range of ProLiant and BladeSystem controllers that support SAS 12Gb/s devices. Typical pairings include Smart Array controllers that provide RAID features, online capacity expansion and background patrol reads. These controllers enable array health features and firmware updates that are essential for long-term reliability in enterprise deployments. Always cross-reference the drive's part number with your server’s compatibility matrix and current firmware revision guidance before mass deployment. :contentReference[oaicite:5]{index=5}

Performance profile and workload suitability

IOPS, latency and sequential throughput

Mixed-use enterprise SSDs like the 849937-001 are optimized to deliver high sustained random IOPS while maintaining low latency for both read and write operations. In real-world mixed transactional workloads—such as small block database requests and virtual machine storage—the drive will deliver significantly higher IOPS and lower tail latency than spinning disks, improving application responsiveness and reducing queuing on controllers. Sequential throughput benefits from the 12Gb/s SAS link, helping with large file transfers, snapshot consolidation and backup windows. Specific numeric IOPS and MB/s figures vary by firmware, controller, queue depth and system configuration; consult your benchmark results in a lab prior to production roll-out to set accurate SLA expectations.

Endurance and reliability expectations

Endurance for mixed-use drives is rated to support moderate to heavy write cycles over enterprise service lifetimes. Enterprise SSDs include overprovisioning and advanced wear management to extend drive longevity. They also typically offer enterprise grade features such as power-loss protection capacitors or firmware mechanisms to protect in-flight data, background garbage collection designed not to interfere with foreground I/O, and adaptive read/write ECC to maintain data integrity. For critical applications, factor drive endurance into your capacity planning and use techniques like wear leveling, thin provisioning awareness and balanced I/O distribution across the array to maximize useful life.

Deployment scenarios and architecture patterns

Primary acceleration tier

The 400GB MU SSD functions well as a front-end acceleration tier in hybrid architectures in which a small number of fast SSDs serve active datasets while bulk capacity is served by dense HDD tiers. When combined with HPE Smart Array or third-party caching solutions, the drive can host hot data sets, pagefiles, swap volumes and VM OS disks to reduce storage latency and improve application throughput across the environment.

All-flash arrays and cache layers

For smaller all-flash arrays, these drives can be used in RAID groups to deliver consistent low latency and predictable QoS. In large systems, they are suitable for read/write caches, log journals or metadata storage where fast synchronous IO is critical. Their MU class makes them versatile for both read-and-write sensitive roles, including database commit logs and distributed storage metadata tiers.

Virtualization and VDI

Virtualized environments and VDI deployments are classic use cases for MU drives: they offer the random write endurance and IOPS characteristics needed to boot hundreds of VMs, handle snapshot churn and maintain acceptable login times. When configured with balanced RAID and proper overprovisioning, a pool of 400GB MU drives can support significant consolidation ratios depending on workload type and optimization practices like linked clones and user profile management.
