ATTO Technology ESAH-1244-GT0 12Gb/s SAS/SATA PCIe 4.0 expansion card
Connects four external and four internal SAS or SATA drives through a low-profile PCIe 4.0 x8 host bus adapter
- TypePCI Express to SAS/SATA Card
- Features4 external/4 internal ports in a low-profile form factor x8
- 12Gb/s SAS/SATA throughput for fast storage access
- PCIe 4.0 x8 host link with PCIe 3.0 backward compatibility
- Four external and four internal ports in low-profile form
- Broad OS driver support including Windows, Linux, VMware and macOS
- Advanced Data Streaming technology for controlled high-performance data streaming
Host bus adapter for mixed SAS and SATA environments
The ATTO ExpressSAS H1244GT provides eight ports split evenly between external and internal connections in a low-profile card. It targets storage administrators who need to attach both SAS and SATA devices through a single x8 PCIe 4.0 slot while maintaining compatibility with existing 6 Gb/s and 3 Gb/s drives. The board serves workstations and servers that require direct-attached capacity without a separate RAID controller.
Thermals noise and power draw
The low-profile form factor fits restricted airflow paths common in dense chassis, and the adapter operates without an active heatsink. Power is drawn solely from the PCIe slot, so no auxiliary connector is required and acoustic impact is negligible in typical server or workstation deployments. Driver support spans Windows, Linux, VMware, FreeBSD, illumos and macOS for broad OS coverage.
Bundled accessories and management software
Each SKU ships with a low-profile bracket and a printed getting-started guide for immediate installation. ATTO ConfigTool and vConfigTool utilities expose firmware updates, link diagnostics and Advanced Data Streaming tuning from a single interface. A target-mode driver development kit is available for OEMs building storage appliances, while WriteStop support adds a hardware-enforced write-block option for forensic or compliance workflows.

Spørsmål om denne varen
How do I install the ESAH-1244-GT0 in a PCIe 4.0 x8 slot, and what bracket mistake should I avoid?
Insert the card into a PCIe 4.0 x8 slot; it also works in PCIe 3.0 slots. Use the included low-profile bracket for low-profile chassis — do not keep the standard bracket if your case needs the low-profile one.
What maintenance will the ExpressSAS H1244GT card need over time?
No scheduled hardware maintenance is required. Keep drivers current using ConfigTool or vConfigTool for Windows, Linux, VMware, FreeBSD, illumos or macOS. Firmware updates apply through the same utilities when ATTO releases them.
What throughput limit appears first on the ESAH-1244-GT0 during sustained 12Gb/s SAS transfers?
The x8 PCIe 4.0 host link caps aggregate bandwidth. Each of the 4 external and 4 internal ports can run at 12Gb/s, but total throughput cannot exceed the PCIe 4.0 x8 ceiling.
