Configuring Local Storage

Basic Disk
 -Default Disk type, Widely compatible, Easily accessible
 -Up to 4 primary or <4 with Extended + Logical
 -No fault tolerance (apart from Raid controller)

Dynamic Disk
No Direct performance benefit
Volumes (not partitions)
Allows for Multi-Disk configurations
 -Simple
 -Spanned (2 disks or more; data faill over to 2nd disk after 1st one is full)
 -Striped (RAID-0) (data is written across all available disks; if one disk fails,remaining disk has no meaningful data on them; no failover,redudancy)
 -Mirrored (RAID-1) (
 -Stripe set with parity (RAID-5) (3 or more diks;data is written to 2 disks with parity data written to 3rd disk.If one of the first 2 disks fail,data can still be retrieved using paritial data from remaining disk and parity data on 3rd disk)
Most Admin don't use
RAID-10 not available

File Systems
FAT/FAT32/exFAT
 -No security, widely compatible
NTFS
 -Security permission,encryption or compression,auditing,quotas,file tagging,large files+Vols
ReFS (Resilient File System)
 -Even larger files,directories, volumes
 -High resiliency: error correction, verification
 -Backward compatible

Partition Types
MBR Disks
 -Traditional partition table, 2TB max
GPT Disks
 -128 partitions;
 -partition up to 8ZB
 -HD up to 18GB
Create+mount VHD, VHDX (can create VHD in Disk management,attach,online and use as a drive)

Storage Spaces (Poor Man's SAN)
SANs are very expensive + require high expertise
Win12 + Win8
Virtual Disks
 -Not VHD, VHDX (virtual hard disks)
 -Formed from storage pooll
Storage Pools
 -1 or more disks (Internal, external, various interfaces)
 -Easily extended with more unformatted disks
 -Can  be fault tolerant
 -Can be thin provisioned (starts with minimum amount needed and still can grow as necessary)

Virtual Disk (Configuration)
Storage layout
 -Simple (no redundancy)
 -2 or 3 way mirror
 -Parity
Provisioning
 -Fixed
 -Thin
Allocation
 -Data Store
 -Manual
 -Hot Spare (in the event of one hard dik failure, hot spare disk is automatically used)
Replacement + Hot spare automatically sync

Steps-> Take physical disks and create storage pool. Then create virtual disk using that storage pool

Storage Tier (hot files<frequently accessed> and cold files)
