Vexata has added NVMe over Fabrics access to its VX-100F array, prodding it to higher performance.
The VX-100F array uses 64 x NVMe flash drives and has FPGA-enhanced controllers accessing the drives in parallel over lossless Ethernet. It delivers 70GB/sec throughput and 7 million IOPS with a 200μs response time.
The 6U arrays now support 8TB drives, giving a maximum raw capacity of 512TB (64 x 8TB SSDs), and 435TB of useable capacity.
VX-OS 3.5 adds NVMe over Fabrics (NVME-oF) support and pumps the performance higher, to 80GB/sec and up to 8 million IOPSin a fully loaded VX-100F 6u chassis.
The improved performance with VX-OS 3.5 comes from:
- Improvements in the scheduling algorithm within the VX-100F system that provides improved latency and hence better throughput performance across all protocols
- VX-OS 3.5 is the first release to support the NVMe over Fabric (NVMe-oF) protocol, so the latencies specified (35μs write and 90μs read) are a result of to the improved efficiency of the NVMe-oF host stack
The system supports all NVMe-oF (NVMe-oF via GbitE using RoCE v2 and NVMe-oF via Fibre Channel) or mixed modes of NVMe-oF and standard FC (SCSI) within the same chassis to allow customers to non-disruptively migrate to NVMe-oF services.
The new software also provides new policy based management and native integration with Active Directory and role-based access control to provide better management in large-scale deployments.
