I previously posted about the migration we performed for a customer for their email server.
This weekend we performed a cutover for another client from an older dedicated MySQL database server to a newer piece of hardware. First, the graph:
And so where the system was under an almost continuous load of 1.0, the system now seems almost bored.
Specs for old DB Server
- Dell PowerEdge 2850
- 2GB RAM
- 2 x 3.6Ghz Xeon with Hyperthreading enabled
- 3 x 146GB 15K rpm SCSI – PERC RAID 5
- Debian Linux 4 – 2.4.31-bf2.4 SMP – 32-bit kernel
- MySQL 4.1.11
Specs for new DB Server
- Dell PowerEdge 2950
- 8GB RAM
- 2 x Dual core 3.0Ghz Xeon with HT disabled
- 7 x 146GB 10k rpm 2.5″ SAS drives – PERC RAID 5
- Debian Linux 6 – 2.6.32-5-amd64 SMP – 64-bit kernel
- MySQL 5.0.51a (soon to be 5.1)
The client is understandably very happy with the result.
