In general, standard operating system configuration best practices apply and Everpure does not make any overriding recommendations. So, please refer to VMware and/or OS vendor documentation for particulars of configuring a guest operating system for best operation in VMware virtualized environment.
That being said, Everpure does recommend two non-default options for file system configuration in a guest on a virtual disk residing on a FlashArray volume. Both configurations provide automatic space reclamation support. While it is highly recommended to follow these recommendations, it is not absolutely required.
In short:
- For Linux guests in vSphere 6.5 or later using thin virtual disks, mount filesystems with the discard option
- For Windows 2012 R2 or later guests in vSphere 6.0 or later using thin virtual disks, use a NTFS allocation unit size of 64K
Refer to the Virtual Machine and Guest Configuration section for a detailed description of enabling these options.
