With regards to the switches, I would argue that they should skip SDN switches all together and get some Cisco Catalysts as TOR Switches. 2x 48-port switches for each rack with redundant core routers in spine-leaf. SDN is cool, but at the c

It seems they have Ceph experience, considering they've made work on AWS.

By Tiering, I'm talking about moving blocks of data from slower to faster or visa verse. If I have 10TB of 10k IOPS storage and 100TB of 1k IOPS storage in a tiered setup, data that is frequently accessed would reside in the 10k IOPS t

I'm not sure I understand your question. A 2TB/2TB disk will have the same number of requests as a 2TB/8TB disk, as they both have the same amount of data. If you are talking physically, 2TB/8TB would theoretically be fa

True about RAID6, I was just commenting on performance. A 2TB will spank an 8TB in any configuration. I would think that GitLab's workload is mostly random, which would pose a problem for larger drives. The SSDs are a great idea, but I

The cost of bandwidth between sites would kill this idea.

It doesn't work like that. 2TB drive will always be faster than an 8TB drive. The amount of data has no effect when compared to the physical attributes of the drive. More platters will increase the response time. Ceph seems to offer Ti

If you are looking for performance, do not get the 8TB drives. In my experience, drives above 5TB do not have good response times. I don't have hard numbers, but I built a 10 disk RAID6 array with 5TB disks and 2TB disks and the 2TB di

The only argument that is needed is cost. Is it cheaper to keep your data local or move it off site? Most of the time, it is cheaper to keep it on site because you don't pay for bandwidth,

You echo the issues I've encountered with Meteor and the reasons why we got rid of it. MongoDB is the worst when having to do, well, anything with it. We've moved to FeathersJS with a SQL Backend and could not be happier.
