Vitesse Semiconductor Corp. recently developed two PCI Express-based SAS RAID-on-Chip (ROC) controller ICs for the entry-level and volume server markets in an effort to speed up the transition to SAS storage of the next generation.
There are two options for the SAS ROC controller ICs.The VSC7250 has eight 3-Gbit/s SAS ports and eight PCI Express (PCIe) lanes, while the VSC7251 has four 3-Gbit/s SAS lanes.Both the VSC7250 and VSC7251 can be used with any pin.
RAID on Demand technology, which enables customers to use a single board design to meet various data protection requirements with a pay-as-you-need model that reduces development costs and speeds up time to market, is the primary feature of the SAS ROC controller ICs.
A significant amount of the infrastructure in the market is based on SCSI technology because it has been the most popular storage interface.
The serialized version of SCSI known as SAS meets the I/O and direct attach storage requirements that traditional SCSI is unable to fulfill.
The Global RAID-on-Chip ICs market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The LSISAS2208 incorporates LSI MegaRAID technology that has been optimized for dual-core operation and a high-performance dual-core 800 MHz PowerPC processor.
An advanced architecture with multiple 500MHz, 128-bit point-to-point internal data paths is combined with a 72-bit DDR3-1333 SDRAM interface and specialized hardware acceleration engines to further improve performance.
With enterprise-level RAID reliability, the new LSI 6Gb/s SAS ROC will assist users implementing server platforms based on solid-state drive storage in maximizing performance benefits. Storage Components Division, LSI.
The OEM customers can use the product now to gain a performance advantage and provide headroom for SSD performance enhancements in the future.
In RAID 5, 6, and 10 configurations, the eight-port LSISAS2208 ROC offers performance levels of up to 400,000 random IOPS.
In application environments like Microsoft Exchange Server, databases, web serving, and business intelligence, it is intended to double the IOPS per dollar of SSDs.
The controller ICs, expanders, host bus adapters, MegaRAID and 3ware RAID controllers, RAID-on-Motherboard (ROMB) solutions, and storage systems that LSI has produced since SAS’s inception are among the best in the market.LSI is the silicon-to-systems supplier of choice for OEMs that want to provide a wide range of storage solutions. This is due to the company’s extensive validation processes as well as its expertise in both hardware and firmware.
