IOCs are PCI Express to SAS+SATA controllers with optional basic integrated RAID (IR) capability supporting RAID levels 0, 1, 1E, 10.Those ICs are known as: SAS/SATA Storage I/O Controllers (IOCs) and RAID-on-Chip ICs (RoCs). LSI makes several types of common architecture ICs that they sell to OEMs as well as use them to power their HBAs and RAID controller cards. 2017, Apr - shipped SAS3408, SAS3508 based Tri-Mode HBAs and RAID adapters ( press release) / first controllers to support SAS/SATA/NVMe moving from PowerPC to ARM A15.2016, Feb - Avago acquired Broadcom Corporation and renamed itself to Broadcom Inc.2013, Dec - LSI acquired by Avago Technologies ( press release).2009, Apr - acquired 3ware RAID adapter business of AMCC ( press release).2008, Sep - sample shipments of SAS2008, SAS2108 ( press release) / second generation SAS/SATA controller, based on PowerPC 440.2006, Feb - introduced first SAS HBAs running Integrated RAID ( press release) / IR firmware.2005, Apr - demonstrated SAS RoC SAS1078 / first SAS/SATA RoC moving from ARM 9 to PowerPC 440.2004, Jan - delivered first SAS controller SAS1064 ( press release) / first generation SAS/SATA controller based on ARM 9.2003 - released LSI53C1035 RoC / first RoC built on Fusion-MPT architecture based on ARM 9 MegaRAID controllers and HBAs start using "same" silicone.
