The new software release includes a new Random Write Accelerator, which yields up to 30 times faster performance for random-write-heavy workloads that frequently update databases, ERP and OLTP systems. Even greater performance gains can be realized on RAID-5 protected datasets that spread data and reconstruction information to multiple locations across different disk drives.
The remarkable write performance speed-ups are most pronounced when using low-cost spinning disks (e.g., SATA disk drives) where each write incurs significant rotational and seek delays to mechanically update blocks on spinning platters. Higher speed flash-based technologies (SSDs), especially prone to write-amplification and rapid wear, benefit from the Random Write Accelerator as well, delivering up to 3.6 times more IOPS.
Doubling the possible number of nodes in a DataCore Virtual SAN is particularly valuable for latency-sensitive applications distributed over large-scale clusters, as well as virtual desktop (VDI) deployments for thousands of users.
Scaling out the configuration across more nodes enables better distribution of the workloads and segmentation of the physical storage capacity. DataCore’s zero-touch failover capabilities ensure workloads and applications are not disrupted in the event of a node or storage failure. The internode mirrors can also be stretched over metro-wide distances up to 60 miles (100 kilometers) to improve overall availability and business continuity. Scaling out to more nodes also enhances the overall resiliency of the infrastructure.
