Folks, ISP 7.1.7.300 on RHEL 6 10G connectivity
We need some guidance on trying to figure out why ISP/TSM write perform to ISILON storage (via FILE DEVCLASS) is so horrible. We recently attached 200TB of ISILON storage to this server so we could empty the 36TB of onboard disk drives to move this server to new hardware. However, per my OS and SAN folks, we are only seeing 1Gbs level of data movement from the ISP server. Doing a regular file copy to this same storage peaks at 10Gbs speeds. So what, if anything, are we doing wrong when it comes to configuring the storage for ISP to use? Are there some secret controls/settings/options to tell it to use the storage at max-speeds? We tried changing the Est/Max capacity thinking larger files would reduce the overhead of allocating new pieces constantly. Changed the Mount Limit to a bigger number. Nothing has helped. Only thing uses the storage right now is migrations from the original disk stgpool. -- *Zoltan Forray* Spectrum Protect (p.k.a.
