SAS HBA Card Compatible with LSI 9212 4i4e RAID Controller, 8 Port 6Gbps PCIe 2.0 x 8, IT IR Mode, 4 Internal SATA and 4 External SAS Ports, for Server NAS Workstation

HIGH SPEED MULTI-CHANNEL STORAGE EXPANSION: Featuring 8 independent channels at 6Gb/s for SAS/Serial ATA, this HBA card supports automatic negotiation of 1.5Gb/s, 3Gb/s, and 6Gb/s rates, significantly enhancing single-channel bandwidth by 100% compared to the previous 3Gb/s model, connecting up to 256 storage devices to meet large-scale data storage needs.
FLEXIBLE INTERNAL AND EXTERNAL PORT: Designed with a combination of 4 internal Serial ATA and 4 external SAS (SFF-8088) ports, this SAS HBA card allows direct connection to standard Serial ATA drives without extra adapters, while the external ports support further storage expansion via expansion enclosures, catering to both local and external storage requirements.
DUAL MODE INTELLIGENT WORKING MECHANISM: This RAID controller card supports seamless switching between IT mode and IR mode. In IT mode, it delivers pure SAS/Serial ATA control capabilities to eliminate soft RAID stack delays, ideal for performance-driven direct attached storage. In IR mode, users can utilize RAID 0, 1, 1E, 10, and JBOD features for data redundancy and read/write acceleration.
ENTERPRISE-LEVEL STABILITY: Built on the LSISAS2008 controller chip and equipped with a 533MHz PowerPC 440 I/O Processor, this enterprise HBA card boasts an average MTBF exceeding 2 million hours and is compatible with major operating systems, including Linux (SuSE), and VMware, ensuring robust data protection through the T-10 data protection model.
LOW POWER CONSUMPTION: Utilizing a PCI Express 2.0 x8 interface with a bus rate of 5GT/s, this HBA card employs spread spectrum clocking (SSC) technology to reduce electromagnetic interference. With onboard flash memory and NVSRAM support for stable firmware execution, it supports 320,000 in random read/write performance while maintaining low power consumption under high-load scenarios.
