DocumentDocumentSetting Up Your Dell SCv2080 Storage System 1 Before You Begin Warning! Before you set up and operate your Dell system, review the safety instructions that came with your system. Unpack Storage Center Equipment A Dell SCv2080 includes: · Drives · Storage system chassis · Mounting rails (2) · Getting Started Guide Develop a Configuration Plan Before installing the storage hardware, develop a configuration plan where you can record host server information, switch information, and VLAN information. Record system information on the worksheet in the Getting Started Guide. · System management IPv4 address for Storage Center · IPv4 address for each storage controller · Domain name · DNS server address Consider Plans for Multipath/Failover Redundancy is provided by fault domains, which allow alternate paths if a path fails. Fault domains are determined by the number of independent Fibre Channel (FC) fabrics or iSCSI networks. Each switch carries a separate fault domain. If a port fails, any port within the same fault domain takes over for the failed port. Dell recommends using multipathing, so that volumes are mapped to ports in more than one fault domain. More Information For operating system, host bus adapter (HBA) and switch requirements, see the Dell Storage Compatibility Matrix on the Dell Tech Center at http://en.community.dell.com/techcenter/storage. For additional deployment instructions, see the Dell Storage Center SCv2080 Storage System Deployment Guide on dell.com/support. 2 Rack Chassis and Optional Enclosure Warning! The storage system chassis is heavy. Do not attempt to lift the chassis without assistance. Use the racking instructions included with your package to rack the chassis. Mount the storage system chassis and expansion enclosures in a manner that allows for expansion in the rack and prevents the rack from becoming top-heavy. Dell recommends mounting the storage system chassis in the bottom of the rack. 3 Install Hard Drives The minimum number of drives for an SCv2080 storage system is 28, which is one full, front row in the top drawer and one full, front row in the bottom drawer. 1. Push and hold both drawer latches toward the center of the drawer and pull the top drawer all the way out until it stops. 2. Populate the first row in the drawer with 14 drives. Insert each disk drive in carrier (DDIC) into the drawer, one at a time. Populate each row with identical drives. Do not mix types, speeds, or sizes in a single row. 3. Close the drawer after adding the first row DDICs. 4. Repeat this process for the bottom drawer, populating the first row with 14 drives. CAUTION To maintain proper airflow, populate the remaining rows in the following order: top drawer middle row, bottom drawer middle row, top drawer back row, bottom drawer back row. 4 Prepare the Host Servers Refer to the Dell Storage Compatibility Matrix for a list of supported HBAs or iSCSI network adapters. Windows and Linux Hosts Install the HBAs or network adapters, install the drivers, and make sure that the latest supported BIOS is installed. Fibre Channel 1. Install Fibre Channel HBAs in the host servers. 2. Install supported HBA drivers and make sure that HBAs have the latest supported firmware. 3. Use the Fibre Channel cabling diagrams to cable host servers to switches. Connecting host servers directly to the storage system without using Fibre Channel switches is not supported. iSCSI 1. Install iSCSI HBAs or network adapters dedicated for iSCSI traffic in the host servers. 2. Install supported HBA drivers and make sure that HBAs have the latest supported firmware. 3. Use the iSCSI cabling diagrams to cable the host servers to switches. Connecting host servers directly to the storage system without using Ethernet switches is not supported. 4. Assign IP addresses to each iSCSI port to match the subnets for each fault domain. CAUTION: Make sure to assign the correct IP addresses to the HBAs or network adapters. Assigning IPs to the wrong ports can cause connectivity issues. NOTE: If using jumbo frames, enable and configure jumbo frames on all devices in the data path: adapter ports, switches, and storage system. SAS 1. Install SAS HBAs in the host servers. 2. Install supported HBA drivers and make sure that HBAs have the latest supported firmware. 3. Use the SAS cabling diagram to cable the host servers directly to the storage controllers. VMware ESXi Hosts Install the HBAs or network adapters and make sure that the latest supported BIOS is installed. Fibre Channel 1. Install Fibre Channel HBAs in the ESXi hosts. 2. Use the Fibre Channel cabling diagrams to cable ESXi hosts to switches. Connecting ESXi hosts directly to the storage system without using Fibre Channel switches is not supported. iSCSI 1. Install iSCSI HBAs or network adapters dedicated for iSCSI traffic in the ESXi hosts. 2. If using network adapters, create a VMkernel port for each adapter. (One VMkernel per vSwitch) 3. Assign IP addresses for each adapter port to match the subnets for each fault domain. CAUTION: Make sure to assign the correct IP addresses to the HBAs or network adapters. Assigning IPs to the wrong ports can cause connectivity issues. NOTE: If using jumbo frames, enable and configure jumbo frames on all devices in the data path: adapter ports, switches, and storage system. 4. If using network adapters, add the VMkernel ports to the iSCSI software initiator. 5. Use the iSCSI cabling diagrams to cable the ESXi hosts to switches. Connecting ESXi hosts directly to the storage system without using Ethernet switches is not supported. SAS 1. Install SAS HBAs in the ESXi hosts. For more information about configuring VMware ESXi hosts with SAS HBAs, see the Dell Storage Center SCv2080 Storage System Deployment Guide. 2. Use the SAS cabling diagram to cable the ESXi hosts directly to the storage controllers. NOTE: Configure only one ESXi host at a time. 5 Deploy the Host Servers The SCv2080 storage system supports Fibre Channel, iSCSI, and SAS protocols to connect the Storage Center to host servers. Fault domains provide fault tolerance at the controller level. If you are using Fibre Channel, incorporate your switch zoning strategy with the fault domains. Dell recommends using redundant cabling to avoid a single point of failure. To connect the storage system: 1. Identify the protocol being used to connect the host servers to the storage system. 2. Refer to the diagram below that corresponds to the proper protocol. These cabling guidelines ensure the configuration has redundancy and failover capability. For more information about cabling, see the Dell Storage Center SCv2080 Storage System Deployment Guide.
