153153
| **vSANCacheReservation** | Percentage of cache reservation for the policy. <br>- The default value is `0`. <br>- Valid values are `0` to `100`.|
154154
| **vSANIOLimit** | Sets limit on allowed input/output (IO). <br>- The default value is unset. <br>- Valid values are `0` to `2147483647`. <br>- Input/output operations per second (IOPS) limit for the policy. |
155155
| **vSANDiskStripesPerObject** | The number of hard disk drives (HDDs) across which each replica of a storage object is striped. <br>- The default value is `1`. Valid values are `1` to `12`. <br>- A value higher than `1` might result in better performance (for example, when flash read cache misses need to get serviced from HDD), but also results in a higher use of system resources. |
156-
| **vSANObjectSpaceReservation** | Object reservation. <br>- The default value is `0`. <br>- Valid values are `0` to `100`. <br>- `0` = thin provision <br>- `100` = thick provision.|

| **VMEncryption** | Sets VM encryption. <br>- The default value is `None`. <br>- Valid values are `None`, `Pre-IO`, and `Post-IO`. <br>- Pre-IO allows virtual IO (VAIO) filtering solutions to capture data before VM encryption. <br>- Post-IO allows VAIO-filtering solutions to capture data after VM encryption. |
158158
| **vSANFailuresToTolerate** | Number of vSAN hosts' failures to tolerate. <br>- The default value is `R1FTT1`. <br>- Valid values are `None`, `R1FTT1`, `R1FTT2`, `R1FTT3`, `R5FTT1`, `R6FTT2`, and `R1FTT3`. <br>- `None` = No data redundancy.<br>- `R1FTT1` = 1 failure - `RAID-1` (mirroring).<br>- `R1FTT2` = 2 failures - `RAID-1` (mirroring).<br>- `R1FTT3` = 3 failures - `RAID-1` (mirroring).<br>- `R5FTT1` = 1 failure - `RAID-5` (erasure coding).<br>- `R6FTT2` = 2 failures - `RAID-6` (erasure coding). <br>- The `None` (no data redundancy) option isn't covered under Microsoft's SLA.|

| **vSANSiteDisasterTolerance** | Valid only for stretch clusters. <br>- The default value is `None`. <br>- Valid values are `None`, `Dual`, `Preferred`, `Secondary`, and `NoneStretch`. <br>- `None` = No site redundancy. This option is recommended for nonstretch clusters and not recommended for stretch clusters. <br>- `Dual` = dual site redundancy. This option is recommended for stretch clusters. <br>- `Preferred` = No site redundancy - Keep data on Preferred (stretched cluster). <br>- `Secondary` = No site redundancy - Keep data on Secondary Site (stretched cluster). <br>- `NoneStretch` = No site redundancy - not recommended. For more details, see [For vSAN stretched clusters, don't use a storage policy with locality=none](https://kb.vmware.com/s/article/88358).|
