STA Plugfest: Microchip/Microsemi Brings 24Gb SAS Storage Expanders and Controllers
Driving toward vendor interoperability and demonstrating how 24Gb SAS alleviates storage bottlenecks in data centers
This is a Press Release edited by StorageNewsletter.com on July 3, 2019 at 2:07 pmMicrochip Technology Inc., via its Microsemi Corporation subsidiary, participatee in the industry’s plugfest for the SCSI Trade Association‘s 24Gb SAS standard that defines how data is moved to and from storage devices in data centers.
As a first company to demonstrate 24G SAS expanders and storage controllers, the firm is playing a role in validating the specs in a broad test environment.
In addition to providing products for use in the STA plugfest tests, the company demonstrated how these solutions deliver capabilities beyond the standard to further improve performance and efficiency.
The firm’s SmartROC 3200 and SmartIOC 2200 storage controllers and SXP 24Gb SAS expanders all support Dynamic Channel Multiplexing (DCM) technology which utilizes 24Gb SAS uplinks between controllers and expanders by aggregating connections from lower speed expander-attached SAS-3, SAS-2 or SATA drives. This enables data centers to exploit 24Gb SAS and PCIe Gen 4 infrastructure when using lower-speed drives and removes performance bottlenecks compared to legacy SAS-3 solutions.
Created to support the latest PCIe Gen 4 data center I/O specifications, the 24Gb SAS (SAS-4/SPL-5) standard doubles the storage interconnect bandwidth of the prior SAS standard, eliminates bottlenecks at the CPU host interface and allows more efficient use of legacy storage infrastructure. Product vendors consider the STA plugfest to be a milestone for gauging 24Gb SAS market readiness and aligning roadmaps with upcoming PCIe Gen 4 server launches.
The STA plugfest ran from June 25-27, 2019, at Teledyne LeCroy, Inc.‘s Protocol Solutions Group (PSG) facility in Milpitas, CA.
