Cassandra 1.0.9 Performance

[G man <gm...@gmail.com>]

Hi All,

We are running a 1.0.9 cluster with 3 nodes (RF=3) serving a load of
approximately 600GB, and since I am fairly new to Cassandra, I'd like to
compare notes with other people running a cluster of similar size (perhaps
not in the amount of data, but the number of nodes).

Does anyone have CPU/memory/network graphs (e.g. Cacti) over the last 1-2
months they are willing to share of their Cassandra database nodes?

Just trying to compare our patterns with others to see if they are "normal".

Thanks in advance.
G

is that 600GB in the cluster or 600GB per node ? 
In pre 1.2 days we recommend around 300GB to 500GB per node with spinning disks and 1Gbe networking. It's a soft rule of thumb not a hard rule. Above that size repair and replacing a failed node can take a long time.

If you can share yours and any specific concerns you may have we may be able to help.
