Each Exchange virtual instance has 25 storage groups so we have 50 luns (separate luns for db/log for each storage group) x2 for a total of 100 luns connected to this SCC cluster. I've opened a case with support #2000680173 and I'm sending in the OntapWinDC output from each cluster node.&nbsp; I'm using https as the SDW transport protocol, there are no production mailboxes on this cluster yet. I ran an unverified SME backup on one storage group and while the job was successfull it took about 20 minutes to complete.</SPAN></P></DIV><DIV><P class="MsoNormal"></P></DIV><DIV><P class="MsoNormal"><SPAN style="font-family: 'Arial','sans-serif'; font-size: 10pt;">The environment consists of 4 Windows 2008 hosts with Data Ontap DSM for Windows 3.2.R1, SDW 6.02, SME5.0, host utilities 5.1 connected via FCP to two FAS3170A clusters.</SPAN></P></DIV><DIV><P class="MsoNormal"><SPAN style="font-family: 'Arial','sans-serif'; font-size: 10pt;">The filer are serial #s 70000081, 70000082, 70000085, and 70000086.</SPAN></P></DIV><DIV><P class="MsoNormal"></P></DIV><DIV><P class="MsoNormal"><SPAN style="font-family: 'Arial','sans-serif'; font-size: 10pt;">Has anyone else seen this behavior?</SPAN></P></DIV><DIV><P class="MsoNormal"></P></DIV><DIV><P class="MsoNormal"><SPAN style="font-family: 'Arial','sans-serif'; font-size: 10pt;">Thanks,</SPAN></P></DIV><DIV><P class="MsoNormal"><SPAN style="font-family: 'Arial','sans-serif'; font-size: 10pt;"><BR />Ryan Rothert<BR /></SPAN></P></DIV><DIV><P><SPAN style="text-decoration: underline;"><SPAN style="color: #0000ff;"></SPAN></SPAN></P></DIV></BODY></HTML> Thu, 05 Jun 2025 07:29:17 GMT https://community.netapp.com/t5/ONTAP-Discussions/SDW-SME-slow-to-perform-out-of-band-operations-when-large-number-of-luns/m-p/38391#M9109 rothert 2025-06-05T07:29:17Z Re: SDW/SME slow to perform out of band operations when large number of luns connected to windows host https://community.netapp.com/t5/ONTAP-Discussions/SDW-SME-slow-to-perform-out-of-band-operations-when-large-number-of-luns/m-p/38396#M9111 <HTML><HEAD></HEAD><BODY><P>Part of the SDW 6.0.2 Release notes.</P><P></P><P>HTTP and HTTPS slow when using domain account</P></BODY></HTML> Thu, 09 Apr 2009 06:12:05 GMT https://community.netapp.com/t5/ONTAP-Discussions/SDW-SME-slow-to-perform-out-of-band-operations-when-large-number-of-luns/m-p/38396#M9111 satishv 2009-04-09T06:12:05Z Re: SDW/SME slow to perform out of band operations when large number of luns connected to windows host https://community.netapp.com/t5/ONTAP-Discussions/SDW-SME-slow-to-perform-out-of-band-operations-when-large-number-of-luns/m-p/38401#M9113 <HTML><HEAD></HEAD><BODY><P>Ah....very good catch....curious to know if any difference if you change to RPC authentication?</P></BODY></HTML> Thu, 09 Apr 2009 20:32:48 GMT https://community.netapp.com/t5/ONTAP-Discussions/SDW-SME-slow-to-perform-out-of-band-operations-when-large-number-of-luns/m-p/38401#M9113 amiller_1 2009-04-09T20:32:48Z
