HPE P21868-B21 – 32GB microSD RAID 1 USB Boot Drive
Overview
HPE P21868-B21 is a dedicated OS boot device designed for HPE ProLiant server environments requiring resilient and isolated operating system storage. It provides RAID 1 mirrored boot functionality using dual microSD media.
The device integrates two 32GB enterprise-class microSD cards with dedicated hardware RAID 1 functionality to improve boot reliability and redundancy.
It is commonly deployed in virtualization and enterprise server environments where administrators want to separate operating system storage from primary data drives.
The module connects through an internal USB interface and is optimized for VMware, Linux, and Windows server deployments.
It is designed for HPE ProLiant Gen10 and Gen10 Plus server ecosystems supporting dedicated boot device infrastructure.
Typical Deployment Scenarios
Used in enterprise virtualization hosts for isolated hypervisor boot environments without consuming front drive bays. Common in HPE ProLiant servers running VMware, Linux, and Windows workloads requiring mirrored OS boot protection. Also deployed in data centers where simplified boot management and storage segregation are required.
