HPE suggests replacing 10K HDD with QLC SSD VRO series, but not for all workloads / ServerNews


HPE announced a new series of VRO (Very Read Optimized) drives to replace 2.5 ”10K RPM hard drives and are certified for Apollo, ProLiant and Synergy platforms. Up to 175x faster, 5x lower latency and 3x more energy efficient than the fastest HDDs from HPE. But there is one caveat.

This nuance lies in the fact that the new drives are built on the basis of Micron 96-layer QLC memory and are optimized for a certain type of workload, which is why they are called VRO:> 80% for random reading and <20% for sequential writing in large blocks (128 KB ). In this case, the DWPD reaches 0.8. Inappropriate loading - 100% random recording in 4K blocks - reduces this figure to 0.05-0.2, depending on the capacity of the drive.

The drives have a hot-plug SATA3 interface and are available in 2.5 “(960 GB, 1.92 TB, 3.84 TB, and 7.68 TB) and 3.5” (3.84 TB and 7.68 TB) form factors. 68 TB). The maximum read speed for all drives is 500 MB / s, writing is from 135 (2.5 “960 GB) to 340 (3.5” 7.68 TB) MB / s. Typical to show random read and write IOPS 43000 and 1950 respectively for the first drive and 54000 and 4500 for the second. At the same time, the younger model can record only up to 350 TB, and the older one – up to 700 TB.

Typical workloads for VRO SSDs: SQL / NoSQL databases, Big Data systems, vSAN, object storage, Hadoop, storage systems for AI and machine learning, and so on. All drives are backed by a three-year warranty. According to Blocks & Files, the cost of new products starts at $ 739.99. Despite the fact that the cost of an SSD is still higher than an HDD, given the higher performance, the TCO gain, according to HPE, is noticeable.
