VO004000KWVUR HPE 4TB Read Intensive SFF Hot Swap Solid State Drive.

HPE VO004000KWVUR 4TB NVMe SSD

Capacity and Form Factor

The HPE VO004000KWVUR delivers 4 terabytes (4TB) of high-performance storage capacity, providing substantial space for read-intensive applications while maintaining consistent performance across the entire storage volume. This capacity is specifically engineered to handle large datasets commonly found in server environments.

Physical Dimensions 

Designed with a 2.5-inch Small Form Factor (SFF) profile, this solid state drive conforms to standard server drive bay specifications. The inclusion of a compatible tray ensures seamless integration into HPE ProLiant Gen10 server infrastructure without requiring additional mounting hardware or modifications.

Interface and Performance Characteristics

PCI Express Architecture

Utilizing a PCI Express x4 (NVMe) interface, this SSD delivers significantly higher bandwidth compared to traditional SATA or SAS interfaces. The x4 lane configuration provides maximum theoretical bandwidth of up to 4 GB/s per direction when using PCIe 3.0, eliminating storage bottlenecks in high-demand server environments.

NVMe Protocol Advantages

The VO004000KWVUR NVMe (Non-Volatile Memory Express) protocol is specifically designed for flash storage, reducing latency and increasing input/output operations per second (IOPS). This protocol enables the drive to handle over 1 million IOPS, with queue depths up to 64,000 commands compared to SAS/SATA's single queue of 32-254 commands.

Performance and Endurance Specifications

Read-Intensive Workload Optimization

Classified as a read-intensive solid state drive, the VO004000KWVUR is engineered for applications where read operations dominate the workload profile. This includes database query operations, web serving, virtual desktop infrastructure (VDI), and content delivery networks where data retrieval frequency significantly exceeds write operations.

Speed and Latency Metrics

Sequential Read/Write Performance

The drive achieves sequential read speeds up to 3,200 MB/s and sequential write speeds appropriate for read-intensive workloads. These performance metrics ensure rapid data access and transfer for large files, database operations, and streaming media applications commonly encountered in enterprise server environments.

Random I/O Performance

For random operations, the SSD delivers exceptional read IOPS performance, typically exceeding 400,000 random read IOPS at queue depth 32. This high random read performance is critical for database applications, virtualization, and other server workloads requiring simultaneous access to multiple small data blocks.

NAND Flash Technology

Utilizing high-quality 3D TLC (Triple-Level Cell) NAND flash memory, this SSD balances cost-effectiveness with performance and endurance characteristics suitable for read-intensive server applications. The 3D NAND structure provides higher density and better performance per watt compared to planar NAND technologies.

Digitally Signed Firmware

The drive features digitally signed firmware that ensures only HPE-authenticated firmware updates can be installed. This security measure prevents unauthorized firmware modifications that could compromise drive performance, reliability, or data security, protecting against malicious code injection and firmware-level attacks.

Data Protection and Encryption

Power Loss Protection

Enterprise-grade power loss protection circuits ensure data integrity during unexpected power failures. This feature includes capacitors that provide sufficient backup power to complete pending writes and commit data from volatile cache to non-volatile NAND memory, preventing data corruption.

End-to-End Data Protection

The drive implements comprehensive end-to-end data protection using advanced error correction codes (ECC) and CRC (Cyclic Redundancy Check) mechanisms. These technologies detect and correct errors throughout the data path from host interface to NAND flash memory, ensuring data integrity at all stages.

HPE ProLiant Gen10 Server Integration

Specifically engineered for HPE VO004000KWVUR ProLiant Gen10 servers, this SSD delivers seamless compatibility with HPE Smart Array controllers, HPE iLO management, and HPE Insight management ecosystem. The drive is recognized and supported by HPE server firmware and management tools without requiring additional drivers or configuration.

Hot-Plug Capability

Designed with hot-plug capability, the drive can be installed or replaced while the server remains operational. This feature minimizes downtime for maintenance and capacity upgrades, supporting business continuity in 24/7 operational environments.

Use Cases and Application Scenarios

Virtualization Environments

Ideal for hosting virtual machine images and supporting virtualization platforms such as VMware vSphere, Microsoft Hyper-V, and Citrix XenServer. The high random read performance accelerates virtual machine boot times and improves responsiveness during concurrent VM operations.

Database Applications

Optimized for database servers including Microsoft SQL Server, Oracle Database, MySQL, and PostgreSQL where read operations dominate transaction processing. The low latency and high IOPS improve query response times and support more concurrent database connections.

Comparison with Other Workload 

Read-Intensive vs Mixed-Use SSDs

Compared to mixed-use SSDs, read-intensive models prioritize cost-effectiveness for workloads with high read-to-write ratios, typically exceeding 70/30 read/write distribution. This specialization allows for optimized performance and endurance characteristics at a lower cost per gigabyte for read-dominant applications.

Read-Intensive vs Write-Intensive SSDs

Write-intensive SSDs feature higher endurance ratings and more sophisticated wear-leveling algorithms to withstand constant write operations, making them suitable for write-heavy applications like transaction logging, but at a higher cost. Read-intensive SSDs provide better value for applications where writes are infrequent but read performance is critical.
