hmm bummer, |
2 |
|
3 |
i was hoping it was a system that allowed me to designate a set of nodes to |
4 |
all have their own local harddisk as an always uptodate cache of the cluster |
5 |
filesystem. |
6 |
|
7 |
(eg what coda and lustre do) |
8 |
|
9 |
No offense but i think il stick to mysql for now, as it supports just the |
10 |
functions i need, and with that i can use all the memmory i want. |
11 |
|
12 |
Thanks anyway. |
