Important information about the BOSS device (PCIe
cards M.2 Drive)
The Boot Optimized Server Storage (BOSS) card shipped with XC Series appliances is the appliance boot device. This PCIe card supports
up to two M.2 SATA SSDs congured in RAID1 for high availability.
NOTE: Write intensive activities and processes leveraged by XC Series appliances, are intended to take place on the SSDs and
HDDs and not the BOSS boot device. Any applications defaulting write activity to the BOSS boot drive should be redirected
accordingly.
Examples of write intensive applications not to be run on the
boot device
Following are the examples of write intensive applications not to be run on the boot device:
• System Center Agents.
– System Center Conguration Manager (CCMExec.exe).
– System Center Operations Manager (MonitoringHost.exe).
• Write‐intensive Agents.
• Databases.
• Disk management utilities (third-party disk defragmentation or partitioning tools).
• Additional roles outside of the appliance’s intended use (web server, domain controller, RDS, and so on.).
• Client‐based Antivirus (Hyper-V only).
• Virtual machines. Ensure that the Virtual Machines run only on Solid State Drives (SSDs) and Hard Disk Drives (HDDs).
