Simple multi-site, multi-tier scenario shown, without shared QFS clients Local site SAM QFS MDS creates a local disk archive (1) and tape archive (2) copy and uses a file transfer feature to create remote disk archive (3) and tape (4) archive copies This basic architecture can scale to thousands of SAN clients, hundreds of file systems , billions of files, PB of disk cache, and most importantly, unlimited archive capacity Next, we’ll take a look at core SAM functionality other notes if needed Any 3rd party disk that is supported in Solaris can be used as a disk cache or disk archive Similarly, many 3rd party tape drives and optical disk drives have been tested and qualified to serve as archive targets behind SAM Many customers use 3rd party tools to move data (i.e., rsync - only replicates changed blocks) and parallel FTP to replicate disk cache across WAN, where it is ingested into remote site QFS file system like a new application workload (DR) Remote Site (not SAM Remote) QFS servers talking to each other using SAM-RFTD feature – Transfers only TAR file Export SAMFSDMP for DR / full QFS file system restore Requires remote file system only to enable transfer (for daemon to start up) and cache SAM running on remote server to archive to tape Works on 2 MDS and creates pipe between them NFS across network using parallel FTP to remote server (multithreading) Over IP wire performance issues? Have throttling controls. Local site can only see one copy at remote site Remote site makes own copy to tape archive (local site doesn’t know about remote tape archive) * Here is the family of engineered systems and appliances. On the left you see the purpose build systems, with Exadata designed to run the Oracle database, and Exalogic designed to run Oracle middleware. As well as Exalytics and the database appliances. On the right is the general purpose SPARC SuperCluster which runs the Oracle parallel database, the Oracle fusion middleware parallel java system, and all your
