LSI SAS9211-8i 6Gb/s SAS HBA Controller Price in Bangladesh

If you’re putting together a home server, NAS build, or just need more drive bays for a workstation, this Sun/LSI SAS9211-8i is exactly the kind of card storage enthusiasts hunt for. It’s one of the most trusted HBA controllers out there, and this unit is in genuinely fresh, like-new shape — not a beat-up pull that’s been cycling through eBay for years. It still comes with the original heatsink and box.

What makes this card worth grabbing is its IT Mode support. Instead of forcing your drives behind a hardware RAID layer, it passes each drive straight through to the OS — which is exactly what ZFS-based systems like TrueNAS need, and what Unraid users typically prefer for flexibility and easier drive management. No fighting with proprietary RAID metadata, no surprises if a drive needs to move to another machine.

On the hardware side, you’re getting two internal Mini-SAS (SFF-8087) ports, each capable of connecting up to four drives — so eight drives total off a single card, running at a full 6Gbps per port whether you’re using SAS or SATA drives. It connects over PCI Express x8, so it’ll have more than enough bandwidth even if you’re loading it up with multiple SSDs.

The LSI SAS9211-8i is one of the most trusted and widely used enterprise storage controllers in the server and storage industry. Designed specifically for high-performance storage applications, this SAS Host Bus Adapter provides reliable connectivity between servers and storage devices while delivering exceptional compatibility and performance.

Powered by the proven LSI SAS2008 controller, the SAS9211-8i supports both SAS and SATA drives with transfer speeds up to 6Gb/s per port. The card connects through a PCI Express 2.0 x8 interface, providing ample bandwidth for demanding storage workloads and enterprise applications.

One of the biggest advantages of the LSI SAS9211-8i is its support for up to 8 internal SAS or SATA drives through two Mini-SAS SFF-8087 connectors. This makes it an ideal solution for expanding storage capacity in rack servers, tower servers, NAS devices, virtualization hosts, and enterprise storage platforms.

The controller is particularly popular among professionals building:

• TrueNAS Storage Servers
• Unraid Systems
• Proxmox Virtualization Hosts
• VMware ESXi Servers
• Backup Servers
• Enterprise File Servers
• Data Center Storage Arrays
• High-Capacity NAS Systems

The SAS9211-8i supports both IT Mode and IR Mode firmware.

IT Mode Benefits

In IT Mode, the controller presents each storage device directly to the operating system without RAID abstraction. This mode is highly preferred for:

• ZFS Storage Systems
• TrueNAS Deployments
• Unraid Servers
• Software RAID Solutions
• Storage Virtualization

IR Mode Benefits

In IR Mode, the controller supports hardware-assisted RAID functionality including:

• RAID 0
• RAID 1
• RAID 10

This provides flexibility for organizations requiring storage redundancy and improved performance.

The card offers outstanding operating system compatibility and works seamlessly with:

• Windows Server
• Linux Distributions
• VMware ESXi
• TrueNAS Core
• TrueNAS Scale
• Proxmox VE
• Unraid
• FreeBSD

Its broad compatibility makes it one of the most versatile storage controllers available for enterprise and professional environments.

The PCIe x8 interface ensures sufficient throughput for multiple SSDs and hard drives operating simultaneously. Whether deploying SATA SSDs, enterprise SAS drives, or hybrid storage systems, the LSI SAS9211-8i delivers stable performance and low latency.

For enterprise deployments, the controller is commonly installed in:

• Dell PowerEdge Servers
• HP ProLiant Servers
• IBM Servers
• Lenovo Servers
• Supermicro Systems
• Custom Storage Servers

The card supports both low-profile and full-height brackets, allowing installation in 1U, 2U, and tower server chassis.

This card carries the original Sun/LSI part numbers (N34791-001 / 375-3640-02), so if you’re trying to match an existing Sun/Oracle server setup or just want confirmation it’s the real thing, that’s your reference. It’s a great fit for anyone building or upgrading a TrueNAS box, Unraid server, media server, or general-purpose storage rig where reliability matters more than flashy extras.
