Have no connection with Ready NAS
We installed new router in the office and after the installation we lost connection with our ReadyNAS. We tried to reboot the devices: server, modem and router. It didn't help.We steel have no acces to the server. When I try to enter the server IP address in the browser the page can't be reached.RN3220 / RN4200 Crippling iSCSI Write Performance
I've got a mixed OEM ecosystem with several Tier 2 RN3220's and RN4200's along with Tier 1 EqualLogic storage appliances. All ReadyNAS appliances have 12 drive compliments Seagate Enterprise 4TB drives in them. I wanted to be able to use the ReadyNAS' as iSCSI options, particuarly for maintainance cycles on the storage network, so I re-purposed them from NFS use. Factory reset them onto 6.6 firmware and they have subsequently been upgraded to 6.7.1 with no change in symptoms. The drives have no errors It's a new install, so there are no fragmentation issues etc. The NAS's use X-RAID I've set them up with 2 NIC 1GbE MPIO from the Hyper-V side (I've also tried it on 10GbE and on 1 NIC 1GbE with no impact). 9k jumbo frames are on There are no teams on the RN's Checksum is off Quota is off iSCSI Target LUN's are all thick Write caching is on (UPS's are in place) Sync writes are disabled As many services as I can find are off, there are no SMB shares No NetGear apps or cloud services No snapshots The short summary of the problem is that if I migrate a VM VHDX storage from the EqualLogic on to any of the ReadyNAS appliances, accross the same storage network and running from the same hypervisor, the data migration takes an eternity and once the move completes the write performance is uterrly, utterly crippled. Here are the ATTO stats: Same VM, on the same 1GbE network. In the case of the above over 1x 1GbE, single path, all running on the same switches. Moving the VM back to the EqualLogic storage takes a fraction of the time to move and the performance of the VM is instantly restored. According to the ATTO data above the ReadyNAS should be offering better performance than the substantially more expensive EqualLogic, however in this condition these units are next to useless. If I create an SMB share and perform a file copy of the storage network, I can get 113MB/s off of a file copy on a 1x1GbE NIC, with no problems. So it does not look like a network issue. Does anyone have any ideas? I have one of the 3220's in a state that I can do anything to. The only thing that I haven't done is try Flex-RAID instead of X-RAID, but these numbers do not look like a RAID parity calculation issue. Many thanks,
