SAS HBA Card, LSI SAS 9212-4i4e RAID Card 6Gbps 8-Port PCIe 2.0 x8 | External SAS / SATA, HBA Controller, 256 Devices Connection, Compatible with Wins, Linux, VMware

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 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: The 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 controller chip support for LSISAS2008 and equipped with a 533MHz PowerPC 440 processor, this card boasts an average MTBF exceeding 2 million hours and is compatible with major operating systems, support for Wins, support for Linux (SuSE/), support for 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 support for NVSRAM for stable firmware execution, it supports 320,000 in random read/write performance while maintaining low power consumption under high load scenarios.
