Anyone have any practical experience here, especially using Flash, compressing GPFS metadata? IBM points out that they specifically DON’T support it on there devices (SVC/V9000/StoreWize)</div>

<div><font face="Helvetica,sans-serif"><font face="sans-serif">But </font>–<font face="sans-serif"> </font></font><font face="sans-serif">I</font><font><font face="sans-serif"> could not find any blanket statements that it’s not supported outright. They don’t
mention anything about data, and since the default for GPFS is mixing data and metadata on the same LUNs you’re more than likely compressing the metadata as well. :-) Also, no statements that you must split metadata from data when using compression.</font></font></div>
