Server Fundamentals Flashcards
Print Server?
Manages print request sent by the network
Mail Server?
Manages the transmission of email
Web Server?
Houses a website and manages requests to view that site
File Server?
Provides centralized file storage that can be accessed over the network
Database Server?
Stores and provides access to a database of information
Application Server?
Dedicated to running certain software applications
Tower Server Pros
Traditional Form Factor
Provides the most internal expandability
Includes all necessary components
Tower Server Cons
Takes up a lot of space
Difficult to add additional servers
Rack Servers
Density (more CPUs and RAM in less space)
Easy to add additional servers
Rack enclosur offers neater cabling
How much is a U?
1.75in.
What are the most common rack sizes?
42U and 48U
PCIe Expansion Slots?
allow for additional and faster network ports
Management Port?
for remote configuration and server management
Relation between CPUs and Power?
More CPUs = More Power needed
Why servers have multiple power supplys?
Redundancy
are hot swappable
Modular Servers?
can support 8 full height / 16 half height / 32 quarter height servers
- 16 half height servers are 60% less dense than 1U rack server
Enclosure houses all power, cooling, networking, and server to server communication (minimizes cabling)
What is point of RAID controllers?
remove the load on the processors
in case of drive failure controller can rebuild data on a “hot spare”
Quoting Chassis?
10 drive or 8 drive chassis
- can’t be changed after point of sale / can’t upgrade after
Motherboard?
The glue
- CPUs plug into sockets
- everything on motherboard ties back to CPUs
- copper lanes tie back to CPUs
- more lanes = more bandwidth
Quoting Processor?
aka CPU
- Intel Xeon or AMD EPYC
- Xeon has no integrated graphics card
- 2.3 GHz Speed -> each core will run at that speed
Quoting Memory?
aka RAM
- applications run in RAM
- measured on DIMM cards -> measured by GBs 8-128gbs
- Sweet Spot = Quad 32 and 64 gbs
What are PSUs?
Power Supply Unit
- device in server that regulates power delivery
- within our server we sell different wattages (495W-3000W) (size power supplies according to wattage)
- Hot swappable but must shut down server to change out
NICs?
cards that give connectivity to the network
- Goes in PCIe in the back
- Has its own CPU
- must come from us
Host Bus Adapter?
special type of card for storage traffic and communication
- PCIe slot
BOSS Card?
Boot optimized storage solution
- Separates the server OS from physical drive
- provides performance benefits and redundancy w/ RAID1
- 240gb or 480gb sizes
PERC?
PowerEdge RAID Controller
- piece of hardware that controls the RAID
- H330 = no cache or RAID 5/6
- H730P = 2GB Cache (Standard)
- H740P = 8GB Cache
