Our team is working on one project like logging as a service based on ece. We need to use raid arch because we have a very high data availability requirement.
After some investigation, raid 50 seems to be a better decision.
Do you guys use raid 50 on elastic cloud?
Can you give me some tips if we need to provide 8 TB storage size per ece allocator node?
For example, how many disks should we use and how much size is each disk for the raid 50 arch?
I believe we have seen use of RAID-50 and RAID-60 in ECE in practice, both are definitely safe
I don't have much to offer on the 2nd question beyond standard RAID-50 knowledge ... eg if you went with the minimum of 6 disks (2 RAID-0 x 3-RAID-5) then 2TB/disk for each of the 6 disks would give you 8TB (in 2 leg config, you "lose" 2 disks' worth of storage. so
(6-2)*2TB=8TB) .. but other configurations are possible with different price/performance/redundancy trade-offs
(Note also that with the hot-warm configuration you can choose different price points for different allocators .. eg spend more on the allocators that would host the newer data to get better performance there)
Thanks for your detailed answer!
