Supermicro Launches Best in Class UIO SAS Cards


Super Micro Computer, Inc. (NASDAQ: SMCI), a leader in application optimized, high performance server solutions, today announced availability of four UIO SAS RAID adapters based on the high performance Intel® IOP348 I/O processor (formerly codenamed “Sunrise Lake”). Supermicro UIO cards with the Intel IOP348 storage system-on-a-chip (core speed 1.2GHz) deliver enterprise-class SAS and advanced RAID data protection. Optimized for Supermicro Universal I/O (UIO) servers, these high-performance UIO SAS cards provide RAID support and internal/external connection to SAS/SATA storage or backup devices. Supermicro AOC-USAS S-Series UIO cards deliver incredible performance, especially in the RAID-5 write cycle.

“These versatile new UIO cards allow users to customize their SAS solution by choosing the card that is best for their specific application,” asserts Charles Liang, CEO and president of Supermicro. “When installed, the UIO SAS card becomes part of the serverboard, and the system still retains all of its PCI-Express and PCI-X slots for expansion cards.”

“Based on high-performance, power-efficient Intel XScale® technology, the Intel® IOP348 I/O processor delivers enterprise-class SAS and advanced RAID data protection with significant flexibility and interoperability”, said Mike Wall, Storage General Manager, Intel® Server and Storage Platform Group. “The Intel® IOP348 I/O processor enables Supermicro to deliver high performance SAS solutions with their new SAS Universal I/O cards.”

With eight ports at 3 gigabits per second each, these SAS solutions can achieve an aggregated 2.4GB per second throughput. All of these new UIO cards support RAID 0, 1, 10 and the two higher end cards also support RAID 5 and 6. For those who want to connect external storage or backup devices, these controllers are capable of supporting up to 128 hard drives. A battery backup option is also available for these cards.

Supermicro UIO servers support Quad-Core Intel® Xeon® processors and feature earth-friendly, high-efficiency power supplies to maximize performance-per-watt savings and reduce total cost of ownership (TCO). Customers can now choose from the following selection of IOP348-based UIO SAS cards:
