Question JBOD enclosure/chassis that holds more than 5 HDDs with only ONE eSATA Port?

[CoconutGilligan]

I have a DVR Security System with one eSATA port. It is connected to a 5 disk RAID tower via eSATA. I need more storage!

DVR VANGUARD II 16x8H https://www.everfocus.com/product/ins.php?index_m1_id=3&index_m2_id=24&index_m3_id=77&index_id=792

RAID enclosure SY-ENC50122 https://www.sybausa.com/index.php?route=product/product&product_id=1068

I've been running RAID tower with the RAID switches turned OFF. Not sure if this is RAID NORMAL or JBOD. Either way, it has been working for a couple of years fantastically. The DVR has a storage capacity of 8TB per disk max, so higher capacity disks aren't an option. I am trying to find some kind of enclosure/chassis that will hold more than 5 disks and will communicate through one single eSATA port. This DVR does NOT allow me to install RAID software. It just sees individual disks and gives me an option to format and record, nothing else is possible.

Anyone got any ideas? Know of any daisy chain enclosures? SAS? I do have the two internal SATAs occupied. Looking for about 8-10 external disks, preferably 3.5".

Am I overlooking something obvious? Is there such a creature as an external eSATA multiplier?

Appreciate the help!

Unfortunately, eSATA is a dying connection type.

But googling for 'eSATA 8 bay' leads to several results.
