27-Oct-2004 - Reseller Servers - Replacement / Upgrade

Post by porcupine » Wed Oct 27, 2004 9:00 am

Hi guys,

Well as some people may have noted, some of our reseller servers are resonably new, and high powered (eg. www2, www3), while others simply are not (www4, www5, and www6). This is simply due to age. The latter of the servers are more lightly loaded, with fewer customers, substantially less load, and perform quite acceptably as we keep those loads low.

Unfortunatly, they are beginning to show their age versus the current technologies. With this, we intend to move all customers from the old servers, to a substantially faster, and newer server. We will be provisioning a new Dual Opteron 242 server to replace all three of the old servers (we may provision a second if it is found to be necessary). It will have the following specs:

Dual 64 Bit AMD Opteron 242 Processors (1.6GHZ @ 64 Bit Each.)
1GB DDR400 Dual Channel ECC Registered RAM (Capacity of 8GB)
1 x 73.4GB Ultra-160 SCSI Drive, 10k RPM
1 x 120GB Serial ATA 150mb/sec drive
Fedora Redhat Core 2
CPanel/WHM

This should be more then enough power to cover the needs of all of the old users from the three above noted servers with ease, but we have additional ones available if this estimate is incorrect.

All customers directly on the www4, www5, and www6 servers should receive a notice from us shortly, we will be handling all of the details of this migration, and will likely perform this in a manner which is reasonably transparent with minimal downtime as customers are moved on a case by case basis, and are currently planning the most basic, yet unimpacting method of performing this migration.

If anyone has any questions, please let me know.

After numerous issues with the old www6 server, we've fully migrated all of the customers from the old www6 server, to the new www6 server (the Dual Opteron) while both servers were live. This process had minimal impact on the users, required no changes to users configuration, IP's, etc. and had an impact of less then 15 minutes of downtime (with no DNS propogation times, as the IP's were bound to the new server), as a result of this migration.

We will be performing a similar process for moving the www4, and www5 based customers to the new www6 server, and hope to have the process perfected in such a manner that allows a completely seamless transition.

Current CPU load on the new system is under 10% average, and 20% peak, and shows promise of holding all the www4 and www5 based customers without breaking 40% cpu load.
