Why we build Data Centre

Data center is a term used to descr ibe the physica l host ing of comp uterequipm ent in a shared data center environment that is mutual ly benef icial to

var ious tenants wi tho ut each in curr ing the fu l l cost o f designing, bui ld ing,

and m ainta in ing the environment .

Data Center Security

There are four levels of security for physical access to securely hostedservers and equipment in data center .

The f irst level is cod e access to the bu i lding . Everyone w il l

need a pr ivate cod e or someone with a code to assist you

to get into the bu i ld ing.

The second level is biometr ic access to the f loo r.

emplo yees or data center visi tors w il l need to pass a

biometr ic Palm scann er to gain access to Data Center.

The third level is the card reader access to th e server area.

Al l access information suc h wh o and when gained access to

the server area are logged. Secur i ty manager can review

such access informat ion at anyt ime.

The fou rth level is locked cabinets for securely ho sted

servers. Keys are requ ired to open su ch lo cked cabin ets.

In addit io n to fou r level phy sical access co ntrol , the data

center is also mo ni tored by secur i ty cameras.
