2 TopicsBest way to build 2 NAS Server (25TB each RAID6) for replication - using existing readynas hardware
we are trying to build 2 NAS servers with around 25TB RAID6 Storage (replicate with each other -21TB used so far) & we need to figure out the least expensive way to do this utilizing existing hardware here is our current setup.. (using 30 Hard drives right now with 7 extra, all on HCL smaller drives are older/expected to fail requires RAID6 (lowest "unused" disk space if possible) RN628X (10TB,10,8,6,6,6,4,3) usable =28.16TB with EDA500 (1.5TB, 2,1,1,1) Raid5 usable =4TB RN716X (10TB,10,4,4,4,4) usable =14.53TB with EDA500 (750GB, 750, 1,2,2) usable =2TB PRO6 (750GB, 750, 500, 1,1,1) usable =2.48TB - Extra drives avail = 500GB, 500,500,150GB,250GB, 160GB, 100GB) so do we simply add larger drives to 716 to achieve 25TB (what sizes HD to add?), then buy a 2nd/3rd EDA500 to attach to the 716 ultize the extra drives in RAID6? or would it be better to pickup a RN528X (for the 8bay CPU/RAM not as important) attach the existing EDA500 - with the goal of getting rid of the PRO6 (using OS6 out of warranty) and 716X (almost out of warranty) - I realize someone might say "get rid of everything & buy a RR4360x" or RR4312x with expansion but it's not in the budget.. or if "moving around HD between NAS servers (for example move the other 10TB into 628x (so you have 4x10TB) & buy <this size HD> for 716x ... another idea on the PRO6 use the oldest 150/250 then when the drives fail upgrade them to 500 etc. - I have been trying to use the Netgear XRaid calulator but it's outdated - so I'm looking for some advise, if the 528x would be the best option as we are also trying to reduce the number of boxes - we just don't like having unused hard drives around..Solved4.2KViews0likes3CommentsNew OS6 NAS No Longer offers XRAID2(Raid6) option
with the original Business Pro NAS (6 drive bays) that shipped with OS Ver 4.x on the original Setup (or Factory reset) - you could specify XRAID2 - Dual Redunancy (XRAID6) Now if you upgrade this NAS to the latest 6.7.1 (it switches to XRAID5) or if you buy a NEW NAS with OS6 like RN716X you cannot get XRAID2(RAID6) because you only have 6 drives.. you must switch to FlexRAID6 here is the problem with XRAID2(Raid6) -vs- Flexraid6 lets say we have a NAS with the following drives (6TB, 1TB, 2.5TB, 4TB, 3TB, 500GB, 750GB) according to the Netgear Xraid Calulator under XRAID6 you would get 6.5Tib usable, 4.55Tib protection and 5Tib unused -vs - 2.5Tib usable 931Gib protection & 13Tib unused. So is the only way to get XRAID6 is to buy a NAS with 8 or 12 Bays? so would it actually be better to NOT upgrade from Ver4.x to 6.x on PRO6 if you value data protection dual redundancy & wanted maximum usable space -vs- flexraid - Lastly the release Notes for 6.7.1 says it now supports "additional FlexRaid options" and " single volume expansion" could someone explain this..Solved
