Physical server requirementsTable 1 Server physical requirementsComponent RequirementPort specifications l The following TCP ports are not used by any other application, and are open in the localfirewall of the server:n MDM: 6611 and 9011n SDS: 7072 (for multiple SDS, ports 7073-7076)n ScaleIO Gateway (includes REST Gateway, Installation Manager, and SNMP trapsender): 80 and 443n Light Installation Agent (LIA): 9099n SDBG ports: MDM 25620, SDS 25640, Multiple SDS 25641-25644 (not 25640).These ports are used by ScaleIO internal debugging tools to extract live informationfrom the system for debugging purposes.l The following UDP port is open in the local firewall of the server:n SNMP traps: 162NoteYou can change the default ports. For more information, see “Changing default ports” in theScaleIO Deployment Guide.Supported operating systemsThe list of operating systems supported by this version of ScaleIO.For the most updated list, see the EMC Simple Support Matrix (ESSM) at https://elabnavigator.emc.com/eln/elnhome.Table 2 Supported operating systems - ScaleIO componentsOperating system RequirementWindows Supported versions:l 2012 R2, 2016 (in v2.0.1.1 and later). Server Core editions are not supported.l For VxRack Node 100 Series, only 2012 R2 is supported.l On all MDM servers, install the EMC-provided PythonModulesInstall.exe on allMDM nodes. The file is supplied on the ISO, or download from the EMC Online Supportsite (search for ScaleIO Python Installation Modules) on https://support.emc.com.To use the secure authentication mode, ensure that these are installed on all servers in thesystem:l OpenSSL 64-bit v1.0.1 or later (v1.1, however, is not supported)l Visual C++ redistributable 2010 package, 64-bitTo use RFcache, ensure that Visual C++ redistributable 2010 package, 64-bit is installed on allservers in the MDM cluster and on all SDSs.IntroductionPhysical server requirements 13
