Whether you’re building a compact NAS, archiving backups, or powering a small office server, the 6805E Single provides predictable, rock‑solid storage performance. Its hardware‑accelerated RAID operations free up CPU cycles for other tasks, allowing your server to serve files, databases, and applications with fewer I/O bottlenecks. And because it’s a true hardware RAID solution, you gain the benefits of cache‑assisted performance, smoother rebuilds after disk failures, and enhanced data integrity features that software approaches simply can’t match.

At its core, this Adaptec card is designed for plug‑and‑play deployment and minimal maintenance. It fits standard PCIe slots in a variety of server form factors and integrates with familiar management software so you can configure arrays, monitor health, and receive alerts with ease. For administrators responsible for uptime and data integrity, the 6805E Single is a dependable partner that balances cost, performance, and reliability in a compact, heat‑efficient card.

• Powerful hardware RAID offloads work from the host CPU. The dedicated RAID processor and on‑board DRAM ensure steady throughput and lower CPU overhead, which translates into smoother application performance even under heavy I/O loads. This is especially noticeable during concurrent backups, virtualization tasks, or multi‑user file access.
• On‑board DRAM cache accelerates reads and writes. Cache memory helps reduce latency and speeds up data access for frequently used files. Write operations benefit from caching as well, enabling faster commit times and improved overall I/O throughput for workloads such as media libraries, databases, and virtual machine storage traffic.
• Flexible, enterprise‑grade RAID capabilities. The 6805E Single supports essential RAID configurations to protect data integrity and optimize performance. With hardware RAID logic handling parity and rebuilds, drive failures can be tolerated with minimal impact on services, and rebuild times are improved compared to software solutions. The card also supports JBOD use cases for direct drive access in certain configurations.
• Intuitive management for easy configuration and monitoring. Admins can set up arrays, monitor drive health, view SMART data, and receive alerts through familiar management interfaces. Clear dashboards and status indicators simplify daily administration, making it suitable for environments where system administrators need reliable visibility without complex setup steps.
• Easy deployment with broad drive compatibility. The 6805E Single works with standard SAS and SATA drives and integrates with existing server backplanes. It’s designed for straightforward installation in PCIe slots, with hot‑swap capable environments and scalable configurations that fit growing storage needs without overhauling the system architecture.

How to install Microchip Adaptec RAID 6805E Single

• Power down and unplug the server. Ensure you follow proper electrostatic discharge (ESD) precautions before touching internal components.
• Open the chassis and locate an appropriate PCIe slot. Choose a slot with adequate bandwidth and clearance for the full card height and length.
• Insert the 6805E Single into the PCIe slot and secure it with a screw. Make sure the card is firmly seated to avoid intermittent connectivity.
• Connect drives to the adapter. Attach the SAS/SATA cables from your backplane or direct‑attach storage to the appropriate ports on the card, ensuring correct lane orientation and cable routing for airflow.
• Power up the server and enter the Adaptec configuration utility. Use the system BIOS or a dedicated hotkey to access the RAID configuration interface. Initialize drives, define the desired arrays, and choose protection levels.
• Install or update management software on the host OS. Deploy the Adaptec management tools to monitor health, performance, and alerts. Apply firmware updates if available to ensure compatibility and stability.
• Verify array health and performance. Run a basic health check, confirm rebuild times, and monitor drive SMART data. Validate that virtual disks appear as expected to the operating system and applications.
• Document configuration for future maintenance. Record array layouts, cache settings, and firmware versions to simplify future upgrades or troubleshooting.

Frequently asked questions

Q: What workloads are best suited for the Microchip Adaptec RAID 6805E Single?

A: The 6805E Single is ideal for entry‑level servers, small business NAS, backups, archival storage, and lightweight virtualization environments where reliable hardware RAID, predictable performance, and simple management are valued. It balances cost with the reliability of true hardware RAID to protect data and speed up storage tasks.

Q: Does the 6805E Single require a battery or cache module?

A: The unit includes on‑board DRAM cache as part of its hardware RAID engine to accelerate I/O. Depending on your configuration and workload, you may opt to implement a battery backup or equivalent cache protection where available, but many configurations operate effectively with standard, non‑battery setups when paired with appropriate backup strategies.

Q: Can I migrate from a software RAID to hardware RAID using this card?

A: Yes. Hardware RAID adapters like the 6805E Single are designed to take over storage protection responsibilities from software RAID formats. Migration paths typically involve configuring new hardware RAID arrays on the card and migrating data through supported tools, while ensuring data integrity and minimizing downtime.

Q: What RAID levels are supported, and how do I choose?

A: The card supports a range of hardware RAID levels suitable for balancing performance and redundancy. RAID 0 offers performance gains without redundancy, RAID 1 provides mirroring for fault tolerance, RAID 5/6 adds parity for data protection with varying fault tolerance, and other configurations may be available depending on the host system. Choose based on your tolerance for data loss, drive reliability, and the importance of write performance for your workload.

Q: Is this card compatible with NVMe or PCIe versions beyond PCIe 3.0?

A: The Adaptec 6805E Single is designed for SAS/SATA storage through PCIe interface capable of standard server configurations. It does not natively provide NVMe support through the same path as NVMe workloads, but it delivers solid performance for SATA/SAS storage in typical enterprise workloads when paired with appropriate drives and backplanes.
