X45xx storage vs 7xxx Unified storage
We are looking at adding to our storage. We would like ~20TB-30 TB. we have ~ 200 nodes (1100 cores) to feed data to using nfs, and we are looking for high reliability, good performance (up to at least 350 MBytes /second over 10 GigE connection) and large capacity. For the X45xx (aka thumper) capacity and performanance seem to be there (we have 3 now) However, for system upgrades , maintenance

Write caches on X4540

The only issue is setting the write...

Data balance across vdevs
I''m migrating to ZFS and Solaris for cluster computing storage, and have some completely static data sets that need to be as fast as possible. One of the scenarios I''m testing is the addition of vdevs to a pool. Starting out, I populated a pool that had 4 vdevs. Then, I added 3 more vdevs and would like to balance this data across the pool for performance. The data may be
