Frequently Asked Questions
What is the primary function of the HPE 878366-B21 HDD Bay Kit? +
The 878366-B21 is a specific drive cage expansion kit designed for the HPE ProLiant DL580 Gen10 server. It allows administrators to increase the local storage density of the chassis by providing the necessary mounting hardware and drive bays to support an additional 8 Small Form Factor (SFF) hard drives or solid-state drives.
Is the 878366-B21 compatible with server models other than the DL580 Gen10? +
This HDD bay kit is engineered specifically for the mechanical and electrical specifications of the HPE ProLiant DL580 Gen10 server series. Using this accessory in non-supported server platforms may lead to fitment issues or improper alignment, so it is strictly recommended for use within the DL580 Gen10 ecosystem to ensure seamless integration.
Does the 878366-B21 kit include the drive caddies or SAS cables? +
This kit includes the internal drive cage components required to expand the storage capacity of your DL580 Gen10. While it provides the physical framework for adding 8 SFF bays, please verify your specific configuration needs regarding drive caddies, as these are often sourced separately to match the specific media types you intend to deploy.
How does installing the 878366-B21 affect the cooling profile of my DL580 Gen10? +
The HPE DL580 Gen10 is designed with modular airflow baffles to maintain thermal efficiency even when fully populated. Adding this 8SFF HDD bay kit keeps your server within HPE's thermal operating guidelines, provided that the system fans and internal air shrouds are correctly seated. Always ensure your server’s BIOS is updated to manage thermal profiles effectively after upgrading hardware.
Do I need a specific RAID controller to utilize the drives installed in the 878366-B21? +
To manage the storage devices installed in this bay kit, your server must have a compatible HPE Smart Array storage controller or a supported Host Bus Adapter installed. The drives will interface with the controller via internal backplane cabling, allowing you to configure them in various RAID levels through the HPE Smart Storage Administrator utility.
Can I mix SAS and SATA drives within the 878366-B21 expansion bays? +
The 878366-B21 backplane supports both SAS and SATA drives, provided they are of the SFF (2.5-inch) form factor. However, for enterprise-grade performance and reliability, we recommend grouping drives of similar interface and speed within the same logical volume or RAID array to prevent performance bottlenecks or management inconsistencies across your storage tiers.
What is the physical installation process for the 878366-B21? +
Installation involves mounting the cage into the front drive section of the DL580 Gen10 chassis and connecting the high-speed data cables to the server's storage controller or internal backplane expander. It is a tool-less or semi-tool-less procedure typical of HPE’s modular design, though we advise reviewing the DL580 Gen10 maintenance guide for specific cable routing instructions.
Does this 878366-B21 kit require additional licensing or firmware updates? +
No specific licensing is required for the hardware itself. However, after installing the bay kit, it is best practice to perform a system-wide firmware audit using the HPE Service Pack for ProLiant (SPP). This ensures that your storage controller and system ROM fully recognize the new hardware and can manage the additional drive capacity correctly.
