Excellent solid state storage performance for HP ProLiant servers

It is estimated that 2.5 exabytes (a billion gigabytes) of data are created every day. To tap the potential of Big Data, applications must read and write more data, faster than ever. HP Enterprise Solid State Drives (SSDs) help you access data faster by providing exceptional performance, extended endurance, and consistently low latency—all while using less power.

And with current transitions in the Hard Disk Drive (HDD) industry, many customers are now experiencing the great performance of SSDs at competitive pricing, especially for capacities under 1 TB.

Peak performance for random data applications
HP Enterprise SSDs are suited to enterprise environments with highly random data under a variety of write-workload applications. The SSDs provide significantly better random read and write I/O operations per second (IOPS) compared to HDDs. While sequential read and write throughput is also improved over HDDs, the greatest benefit is recognized in random data applications. As a result, these high-performance, low-latency, and low-power SSDs provide significant system benefits for applications that previously over-provisioned HDD capacity to achieve better performance.

Enterprise features for data center applications
HP Enterprise Solid State Drives have the key features you need in your data center—full data path error detection, surprise power loss protection, and HP SmartSSD Wear Gauge support. We enable the SmartSSD Wear Gauge through the HP Smart Carrier. With the SmartSSD Wear Gauge utility, HP Enterprise SSDs monitor the amount of data written and report when the device may be nearing its maximum supported lifetime.

Targeted at extreme operating environments or local storage, these drives provide higher I/O throughput, excellent latency, reduced power consumption, enhanced reliability, and faster reads and writes when compared to traditional rotating media. They remove the latency found in conventional rotating HDDs caused by seek time for each read operation, so they deliver high random read performance. Most of these SSDs are available as small form factor (SFF), large form factor (LFF), quick release carriers, or non-hot plug (NHP) for general use across the HP ProLiant Server portfolio. The drives are fully qualified and fit seamlessly into the existing HP server infrastructure.

With no moving parts, more reliability, and greater power savings than traditional rotating media drives, SSDs are finding new applications in the Big Data era.

Compatible with your server environment
HP SSDs are fully tested and qualified to enable compatibility with HP ProLiant and HP BladeSystem solutions. The HP Qualified Option designation places HP SSDs among the best of the best compared to products available on the open market. It is important to note that SSDs on the open market—even those with similar vendor model numbers—may not have the same level of performance, endurance, and quality as HP Qualified Options. For example, the NAND or even the controller in non-qualified products may be different from an HP Qualified Option. HP firmware optimizes our qualified SSD performance, wear leveling, and over-provisioning.

The right SSD for every application
HP Enterprise SSDs are available in three broad categories based on their typical target workloads: Read Intensive, Mixed Use and Write Intensive. The HP SSDs categories include both SAS SSDs and also SATA SSDs.

The categories indicate the number of drive writes per day (DWPD1 ) that you can expect from the drive. (DWPD is the maximum number of 4K host writes to the entire drive capacity of the SSD per day over a five-year period.)

Read Intensive SSDs are typically the lowest price, with a typical Endurance of <= 1 DWPD. Write Intensive SSDs typically have the highest Write performance, with a typical Endurance of >= 10 DWPD. Mixed Use SSDs are for workload that need a balance of strong Read and Write performance, with Endurance typically >1 and <10 DWPD

HP Qualified Options – HP Enterprise Solid State Drives

  • HP Write Intensive Solid State Drives
    HP write intensive 12G SAS SSDs provide high write performance and endurance. They are best suited for mission-critical enterprise environments with workloads high in both reads and writes. Workloads best suited for these WI SSDs include online transaction processing (OLTP), virtual desktop infrastructure (VDI), business intelligence, and Big Data Analytics
  • HP Mixed Use Solid State Drives
    HP mixed use 12G SAS and 6G SATA SSDs are best suited for high I/O applications with workloads balanced between reads and writes. The SAS and SATA SSDs provide the workload-optimized performance required for demanding I/O-intensive applications. When paired with HP ProLiant servers, these SSDs help you meet the challenges of Big Data. They achieve twice the performance and endurance of previous HP SAS and SATA SSDs. The SATA SSDs come with a six gigabit per second (Gb/s) SATA hot-plug interface.
  • HP Read Intensive Solid State Drives
    HP read intensive 12G SAS and 6G SATA SSDs deliver enterprise features for a low price in HP ProLiant server systems. This entry-level pricing is fueling rapid SSD adoption for read-intensive workloads because the cost per IOPS compares very favorably to HDDs. Read Intensive SSDs deliver great performance for workloads high in reads such as boot/swap, Web servers, and read caching, just to name a few.
  • HP Read Intensive M.2 Solid State Enablement Kits
    The HP M.2 Solid State Enablement Kit is the newest addition to our Read Intensive solid state drive family and is best suited for boot/swap. The M.2 Solid State Enablement Kit is available in dual and single 64 GB capacity with an endurance of 0.3 drive writes per day (DWPD). The kits are compatible to ProLiant Gen9 Blades and currently support a 6 Gb SATA interface. Also, the dual and single 120 GB capacity is available in the M.2 Enablement Kit and currently supports ProLiant ML/DL servers.
  • SAS or SATA Interface Available
    HP has a full portfolio of 12Gb/s SAS SSDs. The SAS SSDs transfer data at full duplex (bidirectional) allowing greater I/O bandwidth to alleviate bottlenecks. Additionally SAS uses SCSI commands for error recovery and error reporting, which have more functionality than the ATA command set used by Serial ATA (SATA). HP has a 12Gb/s SAS Expander to scale storage capacity for multi-workload needs. SATA SSDs are great in half-duplex (unidirectional) direct connect scenarios when lower price is a priority.
  • Boost performance with HP PCIe NVMe 2.5" SSDs
    HP NVMe PCIe 2.5" SSDs talk directly to your applications via the PCIe bus, boosting I/O and reducing latency to scale performance in line with your processing requirements. This means, for example, that you can host your entire database on one or more HP PCIe NVMe 2.5" SSDs for enhanced in-memory access and performance. NVMe, or Non-Volatile Memory Express, is a from-the-ground-up industry specification that focuses on efficiency, scalability, and performance. With the introduction of NVMe, an industry interface specification for accessing solid-state storage through PCI Express, manufacturers have a set of guidelines that seeks to release them from the limitations of previous standards, and also provides a wide range of interoperability benefits.



  • Higher performance and better latency
    HP SSDs enable rapid reads and writes of transactional data. On an HDD, random reads require constant repositioning of the read/write head to seek the exact location of data on the platter before the data transfer can begin. However, SSDs have no moving parts or rotating platters that can cause latency problems, and that results in faster access to data. Therefore, with faster seek times, the drives achieve high IOPS, producing quicker data access and better latency.

    The drives also pack the operating performance of several rotating HDDs into the same space as a single HDD, so you can get more performance out of your existing data center.
  • Lower power consumption
    Steadily increasing storage requirements pose power and performance challenges to data centers. Solid state devices have a significantly better performance-to-power rating than traditional rotating HDDs. The lack of a motor greatly reduces an SSD’s power consumption, so the drives draw less energy—less than two watts idle and less than nine watts maximum—for SSDs.
  • Environmental ruggedness
    The inherent environmental ruggedness of SSDs makes them well suited for extreme environments where traditional drives cannot operate. The drives can tolerate significantly higher operating shock and vibration levels compared to traditional rotating HDDs. In fact, they virtually eliminate rotational vibration problems.
  • High reliability
    Reliability is important for any storage medium, and it is essential when considering a storage device that can be used in servers. HP Enterprise SSDs pass a rigorous HP ProLiant qualification of 2.4 million test hours.
  • Investment protection
    HP Enterprise SSDs are a drop-in replacement for existing HDDs. They fit into existing HDD hot-plug bays and require no modification to operating system or infrastructure tools. The drives are recognized as standard SAS or SATA devices with no special changes in firmware or hardware. Although you cannot mix SSDs and HDDs in the same logical array, you can mix them within the system to provide a more effective use of both technologies.
