https://community.hpe.com/t5/disk-enclosures/eva3000-with-progress-database/m-p/3406623#M14012 We intend to buy a EVA3000 with two DL740 with Linux to serve our ERP applicattion.<BR />We use Progress database to build our ERP.<BR />But progress says that they don't support array virualization or NFS systems.<BR />Anyone has any experience with EVAs and Progress ?<BR />They say that they need separate phisical disks because of performance, the database and BeforeWrite transactions separeted.<BR />How can I configure EVA to do that ?<BR />And what about NFS ? Is EVA a NFS system, that is a volume only disponibilized by the appliance ?<BR />Thanks Sun, 24 Oct 2004 13:48:03 GMT AFONSO SOTTOMAYOR 2004-10-24T13:48:03Z https://community.hpe.com/t5/disk-enclosures/eva3000-with-progress-database/m-p/3406623#M14012 We intend to buy a EVA3000 with two DL740 with Linux to serve our ERP applicattion.<BR />We use Progress database to build our ERP.<BR />But progress says that they don't support array virualization or NFS systems.<BR />Anyone has any experience with EVAs and Progress ?<BR />They say that they need separate phisical disks because of performance, the database and BeforeWrite transactions separeted.<BR />How can I configure EVA to do that ?<BR />And what about NFS ?

Depending on the number of drives you have in your EVA, you can configure 1 or 2 diskgroups. One group fra transaction logs and one for the database, thus seperating the 2 diffferent IO patterns. If you have a significant number of drives you can maintain 1 diskgroup, with a VR1 fra logs and a VR5 for data, og VR1 for data depending on your perf. requirements and redundancy.<BR />A virtualised system like the EVA system will deliver more than enough perf. for your database probably either way.<BR /><BR />Regards<BR />Christian Mon, 25 Oct 2004 02:38:06 GMT https://community.hpe.com/t5/disk-enclosures/eva3000-with-progress-database/m-p/3406624#M14013 Christian Schwartz-Søre 2004-10-25T02:38:06Z
