#1.1. Fundamental Notions & Terms 
 
  ELX8-60 Storing Constructure 
 
(1) It is  possible to connect 2 sets of HDD internally (Internal, ATA Interface) and 63 sets of HDD 
externally (External, 2 ports of IEEE1394). 
(2) All of the connected HDDs is recognized as one virtual disk, and  ELX8-60 supports upto 4TB. 
(3) Hdds are divided into primary disk (connected firstly) and auxillary disk. 
 
 
 
 
<Note> 
 
ATA(or EIDE) supports two channel interfaces (Primary/Secondary). Each channel can be connected to 
two devices (Mas ter/Slave, HDD/CD-ROM). However ELX8 -60 supports 1 channel interface internally 
and total two HDDs. In order to prevent confusing VFS2 ’s Primary Disk, we will not use the terms 
(Primary/Secondary). 
 
(4) Primary disk is composed of log partition, normal partition, and alarm partition, and auxillary disk is 
composed of only no rmal partition. So if primary disk has some problem,  all of the recorded data will 
be lost. 
 
 
 
 
<Note> 
 
Log Partition 
To store the information of recorded data 
Normal Partition 
To store the data as normal recording schedule 
Alarm Partition 
To store the data as alarm recording condition (MD or Sensor)
