Virtualization - Hyper V

Virtualization (Hyper-V)
Application virtualization
Service + Application isolation
Easy Deployment
 -VMM (virtual machine manager) templates
 -Self-service portals
Legacy Apps + OS
 -Client Hyper-V
 -MED-V

Server consolidation 
Current hardware is under-utilized
Benefits
 -Higher density
 -Less or centralized management
 -Optimized resources + very high ROI
 -Sand boxing labs
 -Efficient virus scan, Backup
 -Greener
 -Can replicate, migrate

Hyper-V Requirements
Win-12 Full/Core/Hyper-V server
X64 with Second level address translation (SLAT) + Data Execution Prevention (DEP)
Processing - Up to Host + Guest Requirements
Memory - Up to Host + Guest Requirements
Storage - Up to Host + Guest Requirements
 -I/O is Critical
 -Conisder VMs on different Disks+SAN,RAID,SSD,Hybrid SSD
 -Multiple NICs
GUEST MAX
 -1TB RAM, 32 CPU

Hyper-V Client Configuration:Settings
Dynamic Memory
Smart Paging
Resource metering (for billing purpose, etc)
Guest integration services

Hyper-V Settings:Storage
VHD-Original Recipe 2TB Max
VHDX
 -64TB MAX,more resilient,better aligned to large sectors,larger block size(Dynamic/Diff)
Modify VHD (using powershell, we could add/remove features offline without starting OS)
Edit virtual disk wizard (VHD <--> VHDx)
Differencing drives (keeping tomorrow' data/image on different disk/drive)
Pass through disks (add external disk/drive in local OS without the need to go through Hyper-V adapter? performance increase; disk must be offine on host machine first)
Snapshots (point in time instance of the OS)
Fibre Channel Adapter

Hyper-V Settings:Network
Network Virtualization with Vlans
Configure switches (same as VM host only adapter,bridge mode, etc.)
COnfigure available MAC addresses
Synthetic + Legacy virtural network adapters
