Hewlett Packard Enterprise Option PN 461201-B21 ETY (Entry) Solid-state drive with 32GB capacity and SATA 1.5G interface.
HP Enterprise Solid State Drives offer exceptional solid state storage performance for ProLiant servers with peak performance for random data applications. They are designed for enterprise environments that have a variety of write-workload applications and random data.
We all know that SSDs provide much better random read and write I/O operations per second (IOPS) compared to 15K SAS HDDs.
However, the real benefit is recognized in random data applications.
So, these high-performance, low-latency, and low-power SSDs provide extreme system benefits for applications that previously over-provisioned capacity to achieve better performance.
They also remove the latency found in conventional spinning HDDs caused by seek time for each read operation, so they deliver high random read performance.
HP Enterprise Solid State Drives also include surprise power loss protection, and SmartSSD Wear Gauge support.
The SmartSSD Wear Gauge is enabled through the HP Gen8 Smart Carrier. This allows the HP Enterprise SSDs to monitor the amount of data written and let you know when the device is nearing its max supported lifetime.
Reliability is critical for any storage medium, especially so when used in your servers. This generation of HP Enterprise SSDs is expected to have an overall reliability similar to traditional HDDs.
HPE SSDs are fully tested and qualified to assure compatibility with your HP ProLiant and HP BladeSystem solutions.
Available form factors include:
- Small form factor (SFF)
- Large form factor (LFF)
- Quick release carriers
- Non-hot plug (NHP) for general use across the ProLiant portfolio.
There is a correct HP Enterprise SSD for you, and are available in four categories:
The categories listed below indicate the number of drive writes per day (DWPD) that you can expect from the drive.
(DWPD is the max number of 4K host writes to the entire drive capacity of the SSD per day over a 5 year time span.)
|Interface||12/6 Gb SAS||12/6 Gb SAS or 6/3 Gb SATA||12/6 Gb SAS or 6/3 Gb SATA||6 Gb SATA|
|Endurance||High endurance||Mainstream endurance||Value endurance||Value endurance|
|Up to 25 DWPD||Up to 10 DWPD||Up to 1 DWPD||Up to 1 DWPD|
|Workload||Unrestricted read/write||Mixed read/write||High read/low write||High read/dynamic throttled write|
HPE also breaks down their categories this way:
|Write intensive||Mixed use||Read intensive|
|Interface||12/6 Gb SAS or 6 Gb SATA NVMe PCIe||12/6 Gb SAS or 6 Gb SATA NVMe PCIe||12/6 Gb SAS or 6 Gb SATA NVMe PCIe|
|Endurance||>=10 DWPD||>1 and <10 DWPD||<=1 DWPD|
|Typical workload||High read/write applications||Mixed read/write applications||High read/low write applications|
