Hello

We have a NVR-EL-32 currently with 2 hard drives.  I have a couple of questions I have been unable to get the answers to:

1. Is there a way to allow both drives to be used for recordings.  Example is record on drive 1 until it is full, then record to drive 2.  When drive 2 is full, then overwrite and record on drive 1.  If this is possible, could we simply add additional drives and it continue to work this way?

2. From what I understand, the disk groups can be used to record certain channels into certain disk groups.  If this is correct, how can this be done from the web interface of the NVR, or must it be done from the NVR console.

Thanks in advance for the assistance.

Hello,

 

the he nvr will utilize the HDDs in the same matter you explain, unless you set the drive to redundant and you select the channels the will be recording to that redundant drive. This feature allows you to have an extra copy of the data in case one of the drives fail and it will fill up at the same time as the first drive.

Whit disk groups you can assigned a Hard drive to be part of a group and then you can assigned channels to be part of that hdd group, therefore the date of those channels will not be in the same hard drive, instead it will be in the assigned hdd group. This can improve some reading and writing performance because the data is been spread out,

 

thanks

Thanks for the clarification.  It appears a reboot of the NVR may be required as it didn’t seem to start working until after I unchecked the redundancy on each channel, and also unchecked redundancy on the drives, but after these changes and a restart, it’s now utilizing the drives like we want them to.

 

Thanks!
