cat53-vs-ca6While there are three Ethernet cable choices in use—Cat 5, Cat 5e and Cat 6—only the latter two are still considered viable choices for telecom and industrial applications. Since August 2009, when ANSI/TIA-568-C.2 (Balanced Twisted-Pair Telecommunications Cabling and Components Standard) was published, category 5 has been superseded by category 5e and is no longer recognized by this standard. The use of category 5e or better cabling is recommended for all new installations. And yet even with this simplification, there is still a great deal of confusion among Ethernet cable users concerning whether to use Cat 5e or Cat 6 cable. Continue reading

One of the major problem IT depts must deal with is data loss. There are a lot of different technics to prevent a system outage due to data loss is the use of disk arrays.

Redundant Array of Independent Disks (originally redundant array of inexpensive disks) is called the method in which we use multiple HDDs to store data in order to protect our data and provide a fast data recovery time in the worst case scenario. Continue reading
