61. High Availability Hardware Design
•
Hardware redundancy
• Redundant, hot-swappable controllers, PSUs and fans eliminate
single point of failure
• Read/Write on RAID building
• No need to wait until your RAID building is finished, start your
service at the time you finish storage configuration!
•
CacheSafe technology
• During a power outage, BBU provides power to write cache data
into flash for permanent retention
•
LEDs and audible alarms
• Easy component status monitoring

92. Virtual Desktop Infrastructure
• Virtual Desktop Infrastructure = VDI
• Virtual desktop infrastructure (VDI) is the practice of
hosting a desktop operating system within a virtual
machine (VM) running on a hosted, centralized or
remote server.
– From Wikipedia
• VDI = Desktop Virtualization!

95. Application Virtualization
• Virtual application delivery lets IT manage a single instance of each
application in an application hub in the datacenter. Applications are then
delivered via application streaming to Windows PCs for offline use or run
on high-powered servers in the datacenter for online use on any device or
operating system.
