The NeoSapphire 3501 and 3505 support iSER (iSCSI over RDMA) and SRP. iSER does not carry the TCP layer overhead and provides low latency and high throughput performance. The NeoSapphire 3501 and 3505 4KB random write is up to 360K and 600K IOPS, suitable for write-intensive applications in the existing InfiniBand topology.
