I'm looking to purchase a server for some web apps. Our current config is running on a 6 year old Dell PowerEdge machine with SCSI RAID 5, 1 Ghz processor, 32 gig total disk capacity, and a gig of RAM. Upgrading this machine would cost more than it's worth. Boss insists on a name brand server (Dell, HP, Gateway, etc). Budget is in the $2K range. I'd rather stay away from SATA at this point due to the incredible amount of difficulty I experienced putting together a MythTV box earlier this year, and go with SCSI. If no one has specific recommendations, are there any specifics that are definite show stoppers that I should pay attention to when reviewing specs? Best regards, Greg Groth
