Server Upgrades DevBlog

By Keith Cross on Oct 07, 2008

CCP has posted a new Devblog which takes a look at recent upgrades to EVE's Tranquility cluster.

I thought I would add to the recent dev blogs we have had over the last couple of weeks and talk about what has been going on with the Tranquility cluster itself - in relation to the StacklessIO and 64-bit EVE enhancements and where we are heading into the future.

1 x EVE Server Cluster

The EVE Cluster is broken into 3 distinct layers, and a bit of the terminology that is thrown around from time to time (including later in this blog) can be explained quite simply here.

* Proxy Blades- These are the public facing segment of the EVE Cluster - they are responsible for taking player connections and establishing player communication within the rest of the cluster.
* SOL Blades - These are the workhorses of Tranquility and are the primary focus of our ongoing work. The cluster is divided across 90 - 100 SOL blades which run 2 nodes each.
o Node - a single EVE server process. This is the lowest level of granularity within the cluster.
o Dedicated SOL blade - These are SOL blades that we dedicate to one system only. Systems such as Jita, Motsu and Saila reside on these. They run two nodes like any other SOL blade, however the second node is idle and does not load any solar systems.
