A drive for optical discs, either real or virtual. NGT installation requires a VM to have a vacant one on IDE or SATA, and Foundation imaging wants it listed first for BIOS booting.

Each book explains CD-ROM in context, with comparison tables and the common traps.
Terms in this definition
- float
A
FLOATtakes up 4 bytes and has single precision. When exactness counts, convert it toDECIMAL, as totals and averages of it may otherwise make a materialized view refresh in full. - Nutanix Guest Tools
Adds extra management abilities to a guest VM. The bundle holds VirtIO drivers, VSS support and the Nutanix Guest Agent.
- IDE
Visual Studio Code, PyCharm and similar desktop editors are IDEs. Databricks Connect, or the Databricks extension for Visual Studio Code, lets code written in them execute and be debugged on Azure Databricks.
- SATA
A local disk interface, usually slower than NVMe or SAS. vSAN ESA cannot use it since that architecture requires NVMe.
- Foundation
Nutanix's own tool for building clusters, loading nodes first with AOS and a hypervisor that are supported together. Its three forms are the standalone VM, the app and the version in the CVM.
- FIRST
A DAX function available only inside visual calculations. It fetches the value at the start of one axis of the visual's matrix, which makes it handy for comparing each point with the first; its opposite is LAST.
- BIOS
Generation 2 Hyper-V machines use UEFI with Secure Boot; Generation 1 machines rely on this older firmware.
Related terms
- IDE
A VM disk bus that is emulated. Attaching a disk of this type rules out AHV Secure Boot, and Nutanix Guest Tools needs an empty CD-ROM on IDE or SATA.
- SATA
Interface for connecting disks. Nutanix ranks SSDs of this type below NVMe but above HDD, and NGT relies on a VM having a vacant CD-ROM on this bus or IDE.
