Important: The servers should be dedicated to the XtremIO storage array if VMAX or VNX storage arrays are also deployed in the same Converged System. Failure to adhere to this practice might result in performance issues with some or all of the storage arrays. Understanding the architecture 8

9 Converged Technology Extension for VMAX3 storage and Converged Technology Extension for VMAX Each Converged Technology Extension storage has between one to eight engines that provide FC connectivity. For the VMAX 100K, VMAX 200K, VMAX 400K, VMAX 250F and VMAX 250FX, the following table shows the number of FC ports per fabric, for each engine: Number of engines FC ports per fabric (two SLICs per director) FC ports per fabric (four SLICs per director) The following table shows the number of FC ports per fabric, for each engine for the following arrays: VMAX 450F, 450FX VMAX 850F, 850FX VMAX 950F, 950FX Number of engines FC ports per fabric (two SLICs per director) FC ports per fabric (three SLICs per director) For more information about a Converged Technology Extension for VMAX3 storage or Converged Technology Extension for VMAX All Flash storage, refer to the Dell EMC VxBlock and Vblock Systems 740 Architecture Overview. 9 Understanding the architecture

10 Converged Technology Extension for XtremIO storage XtremIO arrays contain one, two, four, six, or eight X-Bricks per cluster. Each X-Brick has four 8 Gbps FC ports. Two of the FC ports connect an X-Brick to each fabric. The following table shows the number of ports per fabric, for each X-Brick: Number of X-Bricks FC ports per Fabric For more information about a Converged Technology Extension for XtremIO storage, refer to the Dell EMC VxBlock and Vblock Systems 540 Architecture Overview. Converged Technology Extension for VMAX3 storage with Symmetrix Remote Data Facility (SRDF) SRDF is a native remote replication technology that can be bundled with a Converged Technology Extension for VMAX3 storage. Replication connections can be made via Ethernet or Fibre Channel (FC) protocols. These connections are made through ports on dedicated SLICs on the VMAX Directors. A minimum of two 16 Gb FC SLICs for host connections are required on each director of every Engine/V- Brick. The use of dedicated SLICs for SRDF limits the number of slots available for other connectivity options (such as enas or additional host connections). Converged Technology Extension for ty storage Each Converged Technology Extension has 2 to 10 FC ports per fabric, depending on the number of hosts. The following table shows the number of FC ports for each platform: Converged Technology Extension storage array Smallest configuration of FC ports per fabric Largest configuration of FC ports per fabric ty 300, 300F, and 350F 2 10 ty 400, 400F, and 450F 2 10 ty 500, 500F, and 550F 2 10 ty 600, 600F, and 650F 2 10 Storage connectivity types Depending on the Converged System configuration, the Converged Technology Extension supports block and file storage. Block storage Follows the same configuration options as the VxBlock and Vblock Systems 350 for block storage. File storage Follows the same configuration options as the VxBlock and Vblock Systems 350 for file storage. Understanding the architecture 10

11 Converged Technology Extension for VNX storage Each Converged Technology Extension has 6 to 14 FC ports per fabric. The following table shows the number of FC ports for each platform: Converged Technology Extension storage array Default FC ports per fabric FC ports per fabric with FC bandwidth enhancement VNX VNX VNX VNX N/A VNX N/A Storage connectivity types Depending on the Converged System configuration, the Converged Technology Extension supports unified or block-only storage. Block storage Follows the same configuration options as the VxBlock and Vblock Systems 340. Unified storage Requires 10 Gbps fiber optic cables to connect the data movers. For more information about a Converged Technology Extension for VNX storage, refer to the Dell EMC VxBlock and Vblock Systems 340 Architecture Overview. 11 Understanding the architecture

12 Administering the system Administering a Converged Technology Extension Converged Technology Extension administration procedures are described in the host Converged System documentation. For more information, refer to the appropriate administration guide for your Converged System. Advanced Settings for Storage Technology Extensions with VMware vsphere 6.0 Use the advanced settings for optimal operation when deploying an XtremIO array with another array type. Changing the following advanced settings to anything other than what is in the table may cause hosts to over stress other arrays connected to the ESX host, resulting in performance degradation while communicating with them.

13 Advanced Settings for Storage Technology Extensions with VMware vsphere 6.5 Use the advanced settings for optimal operation when deploying an XtremIO array with another array type. In vsphere ESXi 6.5, the umber of outstanding IOs with competing worlds parameter is limited to Max Queue Depth of a device. This requires a change in DSNRO for 6.5 on XtremIO. Changing the following advanced settings to anything other than what is in the table may cause hosts to over stress other arrays connected to the ESX host, resulting in performance degradation while communicating with them. Parameter Name VNX and XtremIO ty and XtremIO VMAX3 and XtremIO VMAX and VNX FC Adapter Policy IO Throttle Count 256 (default) 256 (default) 256 (default) default fnic_max_qdepth 32 (default) 32 (default) 32 (default) default Disk_SchedNumReqOu tstanding (set per device or LUN) 32 (default) 32 (default) 32 (default) 32 (default) Disk_SchedQuantum 8 (default) 8 (default) 8 (default) default Disk_DiskMaxIOSize 4 MB 4 MB 4 MB default XCOPY 4 MB 4 MB VMAX3: 240 MB - Claim Rule XtremIO: 256 KB - / Datamover/ MaxHWTransfer Size VMAX3: 240 MB - Claim Rule VNX: 16 MB - / Datamove r/ MaxHWTra nsfersiz e vcenter Concurrent Clones default default default default 13 Administering the system
