FAQ
What types of storage devices can I connect to this SAS controller?
The ATTO ESAH-1280-GT0 supports both SAS (Serial Attached SCSI) and SATA (Serial ATA) storage devices through its eight external 12Gb/s ports. You can connect individual drives, multi-drive enclosures, or storage arrays that utilize SFF-8644 connectors. The controller automatically detects and configures connected devices, supporting mixed environments with both SAS and SATA drives simultaneously.
What RAID configurations does this host bus adapter support?
This adapter provides hardware RAID support for levels 0 (striping), 1 (mirroring), 1E (enhanced mirroring), and 10 (striped mirroring). The hardware-based RAID implementation offloads parity calculations from the host CPU, maintaining performance during RAID operations. These configurations offer different balances of performance, capacity, and data protection suitable for various storage requirements.
Which operating systems are compatible with this SAS controller?
The controller supports Windows (desktop and server editions), multiple Linux distributions including CentOS, Red Hat Enterprise Linux, SuSE Linux Enterprise Server, and Fedora, macOS, FreeBSD, and illumos. ATTO provides certified drivers for these operating systems, ensuring stable operation across diverse IT environments from workstations to enterprise servers.
What is the advantage of PCI Express 4.0 for this storage controller?
PCI Express 4.0 doubles the bandwidth per lane compared to PCIe 3.0, with the x8 interface providing approximately 16GB/s of theoretical bandwidth. This increased throughput reduces potential bottlenecks when multiple high-speed storage devices operate simultaneously, particularly important for the eight 12Gb/s SAS ports. The higher bandwidth supports faster data transfers in demanding applications like video editing, scientific computing, and database operations.
How many storage devices can I connect to this adapter?
The adapter provides eight external SAS/SATA ports, each supporting a direct connection to a storage device or enclosure. Through SAS expanders or multi-drive enclosures, you can connect significantly more devices than the eight physical ports. The 12Gb/s per port bandwidth ensures adequate throughput for multiple high-performance drives operating concurrently in expanded configurations.
What type of warranty comes with this host bus adapter?
ATTO provides a 3-year limited warranty for the ESAH-1280-GT0 ExpressSAS GT host bus adapter. This warranty covers defects in materials and workmanship under normal use conditions. The adapter also features RoHS (Restriction of Hazardous Substances) compliant construction, meeting environmental standards for deployment in regulated environments.
