INTRODUCTION Slack space plays a vital role in the forensic study of any storage media. To do so would be terribly inefficient because the system needs some way of keeping track of which ones are used and which are free (i.e., a list), so doing so for each byte separately would create too much overheard (for each individual byte, i.e. so image I have a hybrid cluster with FTT=1 and RAID1 for all my VMs ( I understand that RAID1 only is available with VSAN standard ), I understsand that if I have 20TB of raw disk capacity, I would have around 10TB usable for this policy.

A file of size 12,500 bytes is to be stored on a hard disk drive where the sector size is 512 bytes, and a cluster consists of 8 sectors. If you enter a deadline date before the end of the task's total slack, total slack will be recalculated by using the deadline date rather than the task's late finish date. This is the best case scenario for vSAN and we still see 31.45% lower usable capacity for vSAN compared to Nutanix, again for the exact same hardware and resiliency level.
