GOLDEN, Colo.--(BUSINESS WIRE)--Demartek, an independent computer industry analyst firm with its own computer test lab, announced that it has evaluated the iSCSI performance of the Chelsio Terminator 6 (T6) 100GbE and 25GbE Unified Wire adapters supporting Target and Initiator offload functionality respectively.
The evaluation showed that for synthetic 4K reads, Chelsio T62100-CR with iSCSI target offload achieved 2.5 Million IOPS or 3 times the IOPS, half the latency, and over 3.5 times the target processor effectiveness compared to 100GbE software iSCSI target. Similarly, for synthetic 4K writes, the T62100-CR with iSCSI target offload achieved 1.4 Million IOPS or 43% more IOPS, 30% less latency, and a 185% increase in target processor effectiveness compared to 100GbE software iSCSI target.
For the Demartek MySQL OLTP real-world workload, the T62100-CR with iSCSI target offload took half the time to complete 5.6 million OLTP transactions, and achieved 78% more IOPS, 41% less latency, and 5.5 times the target processor effectiveness compared to 100GbE software iSCSI target.
“As the enterprise storage systems market sees the increasing adoption of 100Gbps Ethernet network and NVMe flash storage technologies, iSCSI adapters with offload target capabilities are needed to enable maximum performance and efficiency for the broad base of iSCSI applications,” said Dennis Martin, Demartek President. “In our tests, the Chelsio T62100-CR 100GbE adapter with iSCSI target offload significantly outperformed the native iSCSI software target in our synthetic and real-world application tests. In these tests, we measured IOPS, throughput, latency and time to complete the workloads.”
“Our T6 Unified Wire adapters establish a groundbreaking performance bar for Ethernet storage by enabling a 100 Gbps line-rate and extreme IOPS performance for highly efficient iSCSI storage target solutions,” said Kianoosh Naghshineh, CEO at Chelsio Communications. “T6 storage protocol offload technology allows 100 Gigabit Ethernet iSCSI to completely supersede proprietary storage fabrics, while enabling concurrent, future-proof deployment of new Ethernet storage protocols without forcing an infrastructure forklift upgrade. With transition to All-Flash arrays, all storage systems are essentially HPC systems and require offload technology to realize the Flash performance capabilities and value.”
