NAS RAID 1 performance and free space percentage
Hi, We have a RR4312x0 using Flex raid. Two of the disks are RAID 1. The logs report that they are below 20% free and therefore performacnce will degrade. What is the safe percentage level? This RAID 1 volume is home to an iSCSI LUN so I was hoping to use its entire capacity for the LUN. If I need to reduce the LUN size then so be it but I'd love to know how much space of a 2TB volume I can give to it. Also, can I tie an iSCSI LUN/group to access from only 2 calling IP addresses? We have a WIndows Hyper V HOST that is direct connected via the SFP+ ports. This windows iSCSI initiator HOST is also on the same LAN as the 1Gb LAN ports that the business devices connected to the NAS SMB shares via. I need to stop this as it could potentially slow the link down. The iSCSI LUN holds Virtual server VHDs so speed is crucial. Cheers Andy Thanks, Andy.2.3KViews0likes0CommentsReadyNAS4312 HyperV VHD over iSCSI or SMB? RR4312
Hello. We have a new ReadyNAS RR4312. It has 10*2TB SATAs. It will be used to hold the VHDX files from a Windows Server 2016 HOST. The HOST & NAS are connected via 2*10GB SFP+ The HOST server has 2*300GB SAS drives, RAID1 and will also have a VHDX for a WIndows 2016 Server SQL server guest. The VHDX to be stored on the Ready NAS if for the DC/F&P Windows Server 2016 standard. We want best performance for the VHDX stored on the NAS over the 10GB SFP+ to the Server Host (A Fuitsu rack server) iSCSI or SMB? Which would be quicker for VHD access from the Windows HOST? Maybe the NAS storage should be split from the autoconfigured X-RAID (raid 6) to maybe a RAID1 for the VHDX volume to give it more speed, and the remaining 8 disks be reset up as X-RAID (If this is possible?)4.4KViews0likes2Comments
