[SIZE=3]Hi There,[/SIZE]
[SIZE=3]Been having a play with the single license version of Interworx. Must say there are some really cool ideas there. Here?s a few questions that I hope I can get answered.[/SIZE]
[SIZE=3]The purpose for looking at Interworx is for the load balancing/cluster arrangement, but also as a high availability solution, though I understand the High Availability is not yet available though I find it strange it can see what server has the least load, yet can?t tell it?s down or not. Until such time as it is would the following work:[/SIZE]
[SIZE=3]Add a separate IP to eth1 of each server/node and have our monitoring keep an eye on it.[/SIZE]
[SIZE=3]Should a server go down, can it be quickly disabled from the cluster?[/SIZE]
[SIZE=3]When the server is back up & running can it be re-added quickly again and resync itself.[/SIZE]
[SIZE=3]Interwox cluster design:[/SIZE]
[SIZE=3]What is the best way to set up a cluster. From what I can see is that if storage is by NAS then only 1 is allowed, though what if each NAS was controlled by each server as apposed to being handled directly?[/SIZE]
[SIZE=3]Apart from that it seems best to build multiple clusters as apposed to the 1 BIG cluster. i.e. each cluster be 1 or 2 TB of storage. Would this be the best way.?[/SIZE]
[SIZE=3]If so can all clusters use the same DNS (say run DNS on 3 of the CM?s, or at present we have on 4 servers across the globe so Interworx use those instead of it?s internal DNS)[/SIZE]
[SIZE=3]Can you limit what services are on each server? For example if setting up a 4 cluster system (excluding CM) have mail to be handled by 2 servers, Mysql DB?s by the other 2 and all others by all 4 servers.[/SIZE]
[SIZE=3]The weakest point is the CM, yes sure redundant PSU?s & RAID drives etc will help, but is it possible to have that sync?d with to a 2nd CM and handle the failover on the switch (via STP). And maybe a X-over between the 2 CM?s to keep them in sync?[/SIZE]
[SIZE=3]Resellers ? are resellers allowed to oversell, or are they limited by the plans they create. For example. If 10GB of space, they can only allocate 10x 1GB plans (or any plans totaling up to 10GB), or if overselling create whatever and be limited only when they reach 10GB of actual storage as apposed to allocated storage use. We don?t allow overselling, never have and never will.[/SIZE]
[SIZE=3]Excluding our own requirements, those who want a load balanced ?server? would it be best to run say 2 servers with CM on 1 or go a minimum of 3 and keep the CM as a stand-alone?[/SIZE]
[SIZE=3]Think that?s about it so far [/SIZE]
[SIZE=3]Thanks,[/SIZE]
