Software defined storage separates the control layer and the data layer of the traditional storage system, which makes the performance grow linearly as the number of nodes increases and cuts down the cost significantly. As a typical branch of software defined storage, ServerSAN with great flexibility is replacing traditional NAS storage and widely applied as the back-end storage system and shared file system of enterprises’ private cloud.
With the rapid development of the software defined storage technology, the number of upper-layer applications is increasing, and the requirements of a single application for I/O performance also become more demanding. Traditional HDD RAID and even SATA SSD RAID solutions cannot meet the requirements any more. It is necessary to fully tap into the performance advantages of flash memory and break the performance bottleneck in the traditional storage architecture in order to build the service capability of response in several seconds and provide excellent I/O performance for users.
QingCloud and Memblaze jointly build a new all-flash storage solution, which deals well with the I/O performance bottleneck and offers high bandwidth, high IOPS and low latency to virtual machines with the aid of PBlaze Series NVMe SSD.
The deployment of only one PBlaze Series NVMe SSD can offer the IOPS 10 times and the bandwidth 8 times that of the SATA SSD.
With fewer hard drive slots required and lower power consumption per I/O, the batch deployment can greatly reduce the hardware input and energy consumption of data centers.
