Should you use InfiniBand or RDMA over Converged Ethernet as an interconnect? We discuss each technology's effect on performance features such as latency, IOPS and throughput

"Storage sharing has been an important aspect of storage cost control and performance optimization for more than two decades," writes Marc Staimer, in SearchStorage. "The goal has been to squeeze the best performance for the lowest cost out of the shared storage.

"There are essentially four types of shared storage -- block, file, object and parallel file -- commonly found in high-performance computing (HPC) environments. And while each approach must solve multiple storage bottlenecks to achieve its optimal performance, this article focuses on issues related to external interconnect performance to client endpoints..."

Troubleshoot SAN Issues To Improve Performance
SearchStorage, September 3rd, 2020
Common SAN problems include compatibility issues, hardware failures and sluggish storage response times, but a few proven strategies can easily resolve these issues

Brian Peterson and Rich Castagna write in SearchStorage, "Storage area networks can be complicated and temperamental beasts. This is especially true when they're poorly managed. Troubleshooting is tough because a good design isn't always obvious, and Fibre Channel standards are just loose enough to make interoperability a concern.

Fibre Channel (FC) storage area networks have been largely displaced by iSCSI SANs as the block storage choice for many data centers. But while iSCSI is a lower cost alternative that is somewhat easier to manage, can use familiar Ethernet networking technology and might share an existing LAN, FC is still the protocol of choice when high-performance block storage is required. As such, it remains an important storage alternative in most shops, despite the emergence of other alternatives..."

New End-to-End 64Gb/s Storage Solutions Boast Industry-Leading Switches, Adapters, and Transceivers

Broadcom Inc. (NASDAQ: AVGO) announced the availability of the industry's first Gen 7 64Gb/s Fibre Channel switching platforms- the Brocade X7 Directors and G720 Switch, that are foundational infrastructure for the on-demand data center. Additionally, the company today announced the industry's first 64Gb/s Fibre Channel optical transceiver, that is being qualified for use in Brocade switches and Emulex adapters, for end-to-end Gen 7 performance.

Brocade Gen 7 Fibre Channel combines unmatched performance, powerful analytics and advanced automation capabilities to enable an autonomous SAN. New 64Gb/s speed and 50 percent lower latency, powers the network for storage innovations like NVMe flash arrays. Gen 7 also adds new self-learning, self-optimizing and self-healing capabilities to automate SAN management. With the launch of Gen 7 Fibre Channel switching platforms, Broadcom is demonstrating its commitment to develop innovative Fibre Channel technology for the most trusted network for storage.
