HPE Solid State Drives (SSDs)
Excellent solid state storage performance for HPE ProLiant and HPE Synergy 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. HPE Solid State Drives 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
HPE 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
HPE Solid State Drives have the key features you need in your data center—full data path error detection, surprise power loss protection, and HPE SmartSSD Wear Gauge support. We enable the SmartSSD Wear Gauge through the HPE Smart Carrier. With the SmartSSD Wear Gauge utility, HPE 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 HPE ProLiant Server portfolio. The drives are fully qualified and fit seamlessly into the existing HPE 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
HPE SSDs are fully tested and qualified to enable compatibility with HPE ProLiant, HPE Synergy, and HPE BladeSystem solutions. The HPE Qualified Option designation places HPE 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 HPE Qualified Options. For example, the NAND or even the controller in non-qualified products may be different from an HPE Qualified Option. HPE firmware optimizes our qualified SSD performance, wear leveling, and over-provisioning.

The right SSD for every application
HPE SSDs are available in three broad categories based on their typical target workloads: Read Intensive, Mixed Use, and Write Intensive. The HPE 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 workloads that need a balance of strong Read and Write performance, with Endurance typically >1 and

HPE Write Intensive Solid State Drives
HPE Write Intensive 12G SAS and 6G SATA 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.
