     13* Endowed viz chair
     14  - Chimera and ChimeraX license fees have been allocated to endowed chair fund.
     15  - Needs more than a dozen signatures to finalize.
     16  - Search committee meeting not yet scheduled.
     17  - Another pharm chem faculty search has been ongoing for a few weeks.
     18
     19* Plato NAS disk
     20  - Connected by two bonded 10 Gbit/sec connections.  Uses NFS.
     21  - 17 TB RAID volume, all SSD
     22  - nas/databases, nas/home, nas/local mounted on plato nodes.
     23  - Each mount can be compressed on disk, costs about 4 percent in performance read and write.
     24  - Compression is not done on the client so it does not reduce bandwidth.
     25  - Speed of NAS seems faster than beegfs in Scooter's use, and generally more responsive.
     26  - Some files have been copied to databases and local.
     27  - Using 8K buffering good for small files, but not so good for Tbytes of data.
     28  - IPMI and web interfaces to configure NAS.
     29  - Could get more cache memory or NVMe for hundreds of dollars.  Could not use old plato memory, incompatible.
     30
     31* Migrating files to NAS
     32  - Shutdown services that read/write data, then rsync files.
     33  - Change /usr/local symbolic links to point to NAS location instead of beegfs location.
     34  - Priority is to migrate services that have problems on beegfs, web servers, Trac.
     35  - Home directories will stay on beegfs.
     36  - Want mail spool directory to be able to use NAS so mail stays working when beegfs down for maintenance.
     37  - Nobackup directories might stay on beegfs.
     38
