Servers. We agonize over them. We maintain them. Sometimes
we even fear them, knowing that the lifeblood of our organization flows through
them. If anything goes wrong, nightmares follow.
We also upgrade them, and when you find yourself with that
task ahead of you, make sure you do it right. TechRepublic’s Erik Eckel has prepared a helpful list of ten
things to remember when you upgrade your servers. It’s a good checklist,
and if you want to pass it around among your colleagues, here’s a PDF download.
- Always start with
a verified data backup
- Consider creating
an image backup
- Don’t make
multiple simultaneous changes
- Monitor logs
closely after making changes
- Confirm the OS
- Confirm the
chassis supports the upgrade
- Don’t assume plug
- You get what you
- Document changes
Point number 9 is especially important, even in these
Certainly, less expensive disks,
RAM, power supplies, and other components are always available. But when it
comes to servers, it doesn’t pay to cut corners. Only high quality, high
availability components should be deployed in servers. While these items may
cost marginally more than other (lesser quality) alternatives, the performance
and uptime benefits more than offset the additional expense.
Words to the wise.
