Fileysystem
Issues
|
|
|
|
– |
Spread
data among disks
|
|
|
|
• |
Put
heavily used and lightly used databases together
|
|
|
|
• |
RAID-5
or RAID-10 for data
(w/batter-backed cache)
|
|
|
• |
RAID-1 for logs
|
|
|
|
– |
Logs
separate from data
|
|
|
|
• |
Logs
are mostly serialized writes
|
|
|
|
• |
Tables
are updated and used in mostly random fashion
|
|
|
|
– |
If
you have a lot of tables in a database
|
|
|
|
• |
Use
a filesystem designed to handle it
|
|
|
|
• |
ResiserFS
is a good choice
|
|
|
|
– |
A
journaling filesystem
|
|
|
|
• |
Makes
crash recovery faster
|
|
|
|
• |
Better
utilizes disk I/O (usually)
