SolidScale has been around since May and is a serious bit of kit with NVME SSDS and an NVMe over Fabrics class access latency, adding one percent to the access latency of a direct-attached NVMe SSD.
It uses Excelero’s NVMesh server SAN software. SolidScale can function as a shared external array block target, made up from from clustered server nodes, or as a virtual SAN in a hyper-converged style configuration.
The investment is a few million, although no one is saying officially how much.
Excelero was founded in 2014 and has had a single £20 million funding round in 2015.
The investment moves Micron closer access to Excelero’s software development, and a better ability to tune its SSD controller software to optimise SSD performance characteristics of the software.
It might help Excelero software to make better use of QLC (4 bits/cell) flash drives.
