#Readynas duo v2 volume reset driver
Therefore: Set all of your devices to the same, common MTU values.ĭepending on the manufacturer, device and driver these are usually: Name If you have one devices with a higher value and the other devices with a lower value, you will almost certainly see a performance reduction when transmitting from that device. If any one devices does not have Jumbo Frames configured to the same (or higher) value, it will fault. In order the enable Jumbo Frames, the Maximum Transmission Unit (MTU) has to be adjusted on ALL devices in the transmission path – sender NIC, receiver NIC and any and all intermediary switch ports, bridge ports and router ports. The logic being that the fewer CPU cycles being used to process the header and generate and process the CRC and footer, the faster the transfer into memory and thus the smoother the transmission of the data can occur into the disk sub-system. One of the obvious things to try is to enable Jumbo Frames, which allows more data to be transmitted in a single Ethernet Frame before the data has to be re-wrapped in a new header and trailer for Layer 2 transmission over an Ethernet Network. In wanting to use the device simply as a on-line backup appliance, I wanted to try and squeeze as much performance out of it as I could. It is not clear on-line whether anyone has had any actual success with enabling it. The ReadyNAS Duo V2 is not designed for Jumbo Frames and there are no user interface entry points to enable it.
The device was never intended to support performance or even low-end enterprise tasks. The ReadyNAS Duo V2 is a now legacy, ARM based dual 3.5″ drive SOHO NAS appliance with a single NIC and 256MB of RAM.
