Whether for processing the data generated by your business or keeping that deluge of data protected, boosting storage performance is always a priority. With its parallel data streams and low-latency access, NVMe was designed to capitalize on flash’s groundbreaking performance and get around SCSI’s inherent bottlenecks.
Now, with Purity//FA 6.4.2, FlashArray supports NVMe/TCP, the final missing piece required for mainstream adoption of NVMe over Fabrics, in addition to FC and RoCE. Since NVMe/TCP runs on the ubiquitous Ethernet network, businesses get end-to-end performance on an easy-to-deploy and manage network. What’s more, since Ethernet is the network of choice for the cloud, NVMe/TCP enables seamless hybrid cloud deployments and paves the path for cloud operating models such as Pure Fusion.
With NVMe/TCP, organizations now get all the benefits of an NVMe fabric without committing to a dedicated storage network like Fibre Channel or adding specialized RoCE equipment to their Ethernet network. NVMe/TCP delivers the same advantages as NVMe/FC and NVMe/RoCE: increased throughput and decreased latency, and benefiting from using Transport Control Protocol (TCP), which offers:
- Scalability: TCP supports widely available, easy-to-expand networks for growing needs.
- Ease of use: TCP is a “simple” protocol with common and well-known standards that IT staff are already familiar with and trained to manage.
- Reliability: TCP has always been one of the most reliable Ethernet transports, with features such as packet acknowledgment, packet loss recovery, congestion control, etc.
- Worldwide usage: TCP/IP is widely deployed and especially prevalent in cloud and hybrid environments.
35% Better Performance than iSCSI for Demanding Workloads
NVMe/TCP gets around the bottlenecks that made iSCSI less than ideal for performance intensive applications, and unlike iSCSI, NVMe protocol was designed for flash media instead of spinning media. Why is this important? Modern-day applications with strict service level agreements drive the need for the low-latency, high-performance, on-demand networks that NVMe-oF can deliver. In particular, applications that use microservices, everything-as-a-service, or another cloud or hybrid cloud model will benefit from a more efficient storage protocol that runs on Ethernet.
To help customers make the rapid decision to adopt NVMe/TCP, we had a clear goal: to provide significant performance improvements, so they see instant results. The performance advantage of NVMe/TCP over iSCSI was clear in recent benchmark testing. Testing on the FlashArray//X 90R3, comparing NVMe/TCP results to iSCSI results, we saw up to 35% improvement in latency and a 25% increase in throughput/IOPS with FlashArray//X under a heavy load. Squeezing out additional performance in an already existing network shows why we think NVMe/TCP will increase in popularity rapidly.
And unlike some of our competitors, the benefits of NVMe/TCP are available across our full FlashArray product line, not just our performance-oriented FlashArray//XL™ and FlashArray//X R3 systems. So even if you’re using FlashArray//C™ R3 for storing snapshots or running less-demanding workloads, you’ll be able to use NVMe/TCP and see benefits.
