It would need about 350Gb. On Tue, Jun 16, 2009 at 1:12 PM, Daniel Kinzler <daniel.kinzler(a)wikimedia.de

Daniel It's a specialised index, but the resulting API has lots of uses. Query-to-map is one such use. Almost anything that reads data from the OSM API could use XAPI as an alternative. 80n On Tue, Jun 16, 2009 at 1:31 PM, Daniel Kinzler &lt;daniel.kinzler(a)wikimedia.de > > > 80n schrieb: > > It would need about 350Gb. > > Phew.

As far as I see this could be the basis of many other projects. Maybe just give it a try and see how much it will be used? Peter Am 16.06.2009 um 16:42 schrieb Daniel Kinzler &lt;daniel.kinzler(a)wikimedia.de

Looking at the specs again, I see I was wrong - the toolserver is going to have far less room than that. It really can't take 350 GB, it only 584 total. I was calculating with 2TB, but that's the DB server. Reiterating the server specs: * Cassini, the Toolserver: X4150, 2x4 cores, 24 GB RAM, 4*146 GB Disks ~ 1/2 TB * Ptolemy, the database: X4250, 2x4 cores, 32 GB RAM, 16*146 GB Disks ~ 2 TB * Ortelius, squid/render: 1x4 cores, 28 GB RAM, 4*146 GB Disk ~ 1/2 TB So, this means it can only be on the production servers. That would mean extending the original profile the servers were layed out for, and it raises the question of access. How is the XAPI accessed? Is it a standalone server? Does it need apache? So far, I think Ortelius would run squid and lighttpd. Also, who would maintain it on the production boxes? And is mark OK with having an extra service there? -- Daniel Kinzler Software Developer Wikimedia Deutschland Phone +49 30 219 158 260 Imagine a world in which every single human being can freely share in the sum of all knowledge.

I see some server specs here: https://wiki.toolserver.org/view/Servers At some point, if we needed to add more disk space, what is the maximum capacity for the servers? I have spoken with people at NASA about getting a copy of the World Wind imagery (e.g. Blue Marble, Landsat, aerial imagery, or whatever we want). If provided with additional disks of imagery data, can they be added -- probably to the production servers? -Aude
