BlackArmor® NAS 440/420 User Guide (Version 3) 62

group account

In BlackArmor Manager, a collection of user accounts grouped together to make it faster and

easier to manage access to shares. All users in a group have the same level of access to any

particular share. See also user account.

hot-swap

To remove and replace a disk drive without first powering off the server.

HTTP (Hypertext Transfer Protocol)

Rules for exchanging the most common form of documents (hypertext documents) over the

Internet.

HTTPS (Hypertext Transfer Protocol over Secure Socket Layer)

Rules for exchanging HTTP documents over encrypted connections.

JBOD

Just a Bunch of Drives. See span.

IP address

The identifier of a computer, server, or other device on a TCP/IP network. IP addresses are a

sequence of four numbers separated by periods. (For example, 123.456.78.1.) Every device

on your local network has a unique IP address.

link aggregation

A method of increasing the speed of a device’s network connection by using more than one

Ethernet port simultaneously to connect to the network.

If you connect both of your BlackArmor server’s LAN ports to your network router or switch

and set Aggregation in BlackArmor Manager, both connections work simultaneously and in

parallel to move data more quickly—similar to filling a bucket using two hoses instead of one.

local access

Access to the server from a computer on your local network. Or, manual access to the server,

which involves physical contact with the server or its cables. See also remote access.

mirror

A level of RAID protection also known as RAID 1. A mirror is built from two disk drives, where

one disk drive is a mirror of the other (the same data is stored on each disk drive). Compared

to independent disk drives, a mirrored volume provides faster performance, but has only 50%

of the capacity.

NFS

Network File System. An application that lets all users on a network share files that are stored

on different types of computers.
