1 Windws Server Administratin Fundamentals Identify Majr Server Hardware Cmpnents

2 Windws Server Administratin Fundamentals Lessn Overview In this lessn, yu will learn: Server frm factrs Server prcessrs Netwrk cmpnents Strage ptins Memry Server cling Server prts

3 Windws Server Administratin Fundamentals Anticipatry Set What prcessr type is required fr Windws Server 2008 R2?

4 Windws Server Administratin Fundamentals Server Frm Factrs Servers are designed t run fr lng perids withut interruptin, which makes hardware reliability and durability extremely imprtant. Servers typically cntain a higher number f cmputer fans r water cling systems t remve heat. Servers will have hardware redundancy such as: Pwer supplies Fans Hard drives

5 Windws Server Administratin Fundamentals Server Frm Factrs (cntinued) Twer-frm factr Free-standing in twer chassis cnfiguratin Twer-based servers have the same capabilities as rack-muntable servers. Typically used in small business that d nt require mre than ne r tw servers

6 Windws Server Administratin Fundamentals Server Frm Factrs (cntinued) Rack-munted servers Typically fund in businesses that have mre than tw servers Typically munted n rails in a rack cabinet Can be stacked n tp f ne anther and accessed by the rail system, which is similar t a cabinet drawer Reduces the ftprint the server leaves in the datacenter 3U rack-munted server Standard 19" rack cabinet enclsure

7 Windws Server Administratin Fundamentals Server Prcessrs Prcessr selectin will be based n the server rle and server perating system that will be installed. Windws Server 2008 has bth 32-bit and 64-bit versins Windws Server 2008 R2 requires a 64-bit prcessr Multi-cre prcessr A single chip cntaining mre than ne micrprcessr cre Multiplies perfrmance with the number f cres Operating system must be designed t supprt and recgnize multiple cres r prcessrs.

8 Windws Server Administratin Fundamentals Netwrk Cmpnents Netwrk interface cntrller (NIC) A hardware device that cnnects a server s interface t a cmputer netwrk and allws a netwrk-capable device t access that netwrk A NIC is bth a physical and data link layer device n the OSI Reference Mdel. A NIC is typically available in 10/100/1000 Mbps. Cntemprary servers typically are cnfigured with at least tw 10/100/1000 Mbps adapters. Multiple server NICs can be teamed tgether t perfrm as ne, thus allwing fr twice the thrughput as a single NIC. Server 1 has tw 1 Gbps NICs. Bth NICs can be cnfigured t perfrm as a single NIC giving it a ttal thrughput f 2 Gbps.

9 Windws Server Administratin Fundamentals Strage Optins Hard disks servers can be cnfigured with Direct Access Strage (DAS) as well as Strage Area Netwrk devices. DAS is made f a data strage device cnnected directly t a cmputer thrugh a Hst Bus Adapter (HBA). Serial Attached SCSI (SAS) is a cmputer bus used t mve data t and frm strage devices such as hard drives and tape drives. SAN is an architecture t attach remte cmputer strage devices t servers such that the devices appear as lcally attached t the perating system. Typically cnnected using the SCSI prtcl fr cmmunicatin between servers and disk drive devices They are mapped t ther prtcls t frm a netwrk: Fiber Channel Prtcl (FCP) the mst prminent prtcl, mapping SCSI ver fiber channel.

10 Windws Server Administratin Fundamentals Memry Refers nly t a cmputer s main memry, the fast semicnductr strage (RAM) directly cnnected t the prcessr. Memry Types

11 Windws Server Administratin Fundamentals Server Cling In 2010, servers were respnsible fr 2.5% f energy cnsumptin in the United States. A further 2.5% f United States energy cnsumptin was used by cling systems required t cl the servers [1]. Server cling reaches beynd internal fans. Heat generated by data center cmpnents must be remved, therwise the heat will cause a malfunctin. Air cnditining is used t cntrl the temperature and humidity in the data center. A uninterruptable pwer supply (UPS) shuld be a standard cmpnent f any server rack enclsure r data center. UPS is nt used t maintain pwer, but t allw fr a graceful pwer-dwn f all cmpnents r t switch t alternative pwer. [1]"ARM chief calls fr lw-drain wireless". The Inquirer. 29 June

12 Windws Server Administratin Fundamentals Server Prts Servers share similar characteristics t desktp cmputers as it relates t the varius prt ptins available. Standard server prts include: Universal serial bus (USB) SVGA Parallel Serial PS/2 SCSI Optinal server prts may include: Fiber channel Firewire

13 Windws Server Administratin Fundamentals Lessn Review What is the standard unit f measurement fr a rack? Why is planning imprtant when selecting a rack enclsure? Why is it imprtant t have a climate cntrlled data center?
