January 2021 Hardware Upgrades

[Jim]

The hardware has arrived for memory and disk upgrades to the server that houses TM and METAL.  I hope to install them this week, possibly as soon as tomorrow (Wed 1/20).  There will be multiple complete outages of TM and METAL, including this forum.  Watch this thread, the motd on the main TM page, and the project status on GitHub (https://travelmapping.github.io/) for updates.

Been doing some work on C++ subgraph generation this past week where memory bandwidth plays an interesting role; it's made me wonder what noreaster's setup is.

So what's it got?
DDR4?
What mHz?
Dual-channel? Tri-channel? Other?

Current:

32GB (8x4GB) 2400MHz DDR4 RDIMM ECC

Adding 8 more of the same to bump to 64GB total.

I am planning to do the upgrades starting around 9:15 AM EST on Wednesday, January 20.  Expect TM to be unavailable at times throughout the day.

Looks like the DDR4 modules are rated for 2400MHz, but the processor only supports 2133...

On noreaster we have this:

Dual Intel Xeon Processor E5-2630 v4 (10C, 2.2GHz, 3.1GHz Turbo, 2133MHz, 25MB, 85W)

The 2133 here appears to refer to the memory clock:
https://ark.intel.com/content/www/us/en/ark/compare.html?productIds=92981
...which answers my other question: it's 4-channel.

Not bad. That's nominally 178% the bandwidth of lab2, 267% the bandwidth of lab3.
noreaster should be able to churn out subgraphs wicked quick.

The disk is in, but not yet partitioned or in use.  Turns out there was a misunderstanding on the memory, and it has not yet arrived.  We're up at the moment, but I will be doing a lot of reconfiguring so expect ongoing outages this morning.

[Jim]

The database is now on the new SSD.  This post is in part to make sure the forum still works, but also to say TM service disruptions will continue today.

[Jim]

Things still look good after a reboot with the DB and some other things moved to the SSD.  The site should be stable for the next hour or two, then I'll be making more changes.

[Jim]

The main TM site and the forum are now living on the new SSD.  Hopefully this post will work!

[Jim]

I'm still doing some rearranging and configuring, but I don't expect any of it to cause more than very brief interruptions to the operations of the main TM site or the forum.  Please let me know if you notice any new problems that might be a result of today's disk upgrade.

When the new memory chips come in, we'll have another outage, but that should be a lot less disruptive.

Noticed there was a 'theme' link issue since you moved the forum to a different directory.  I've just fixed that issue.

wpt editor does not work anymore (FF, Edge, IE): https://travelmapping.net/wptedit/
Leaflet issue?

[michih]

no, a general issue - on our end? When I load data, the table does not apear

Not sure whether there is a connection to the HW update. It worked yesterday but I had wpt editor opened during the upgrade.

Of course, no cache issue etc. (automatically deleted on closing browser)

wpt editor + mapview + showroute do not work - because of favicon failure!
