Setting Up Your Dell EMC SCv3000 and SCv3020 Storage System (Front-End SAS)
6
Cable the Backend
To add capacity to your storage system, you can connect SCv300, SCv320, or SCv360 expansion enclosures to an SCv3000 series storage system.
Each expansion enclosure includes two Enclosure Management Modules (EMM) in two interface slots.
NOTE:
If the storage system is installed without expansion enclosures, do not interconnect the back-end SAS ports on the storage controllers.

10 Attach the Host Servers (SAS)
Refer to the Dell EMC Storage Compatibility Matrix for a list of
supported SAS 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.
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.
4. Using Storage Manager, click Configure this host to access
a Storage Center and log in to the Storage Center. The
Setup localhost for Storage Center wizard opens.
VMware ESXi Hosts
The Configure VMware vSphere to access a Storage Center
wizard is not supported with SAS HBAs.
1.
Refer to the following Dell Support page for required
procedures to configure hosts:
http://www.dell.com/support/article/how11081
2. Within Storage Manager, use the Create Server option to
manually create the server object.
Configure Host Access to a Storage Center
1.
Open the Storage Manager Client Welcome Screen.
2. Click the Configure this host to access a Storage Center
link and log in to the Storage Center.
3. Follow the steps in the wizard to configure the host to access
the Storage Center and configure best practices for
performing I/O.
When the host configuration is complete, use the Storage
Manager Client to create and map volumes.

CAUTION:
Make sure that the power switches are in the OFF position
before connecting the power cables.
1.
Connect the power cables to both power supply/cooling fan modules in the storage system
chassis.
2. Use the velcro straps to secure the power cables to the storage system chassis.
3. Plug the other end of the power cables into a grounded electrical outlet or a separate power
source such as an uninterrupted power supply (UPS) or a power distribution unit (PDU).
11
Attach the Host Servers (iSCSI)
Refer to the Dell EMC Storage Compatibility Matrix for a list of supported iSCSI network adapters.
Windows and Linux Hosts
Install the iSCSI HBAs or network adapters, install the drivers, and make sure that the latest
supported BIOS is installed.
1.
Install the iSCSI HBAs or network adapters dedicated for iSCSI traffic in the host servers.
2. Install supported iSCSI HBA drivers and make sure that iSCSI 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.
VMware ESXi Hosts
Install the iSCSI HBAs or network adapters (NICs) and make sure that the latest supported BIOS is
installed.
1. Install the iSCSI HBAs or NICs dedicated for iSCSI traffic in the ESXi hosts.
2. 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.
3. Create a VMkernel port for each iSCSI HBA or NIC to be used for iSCSI.
4. 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.
5. If using the software iSCSI initiator and the server has iSCSI offload, the iSCSI hardware initiator
must be disabled.
6. If using iSCSI HBAs, configure Network Port Binding to add the VMkernel ports to the iSCSI
Storage Adapter. Do not bind NICs to the software initiator.
7. If using software iSCSI initiator, add the Storage Center's iSCSI target IPs to the Dynamic
Discovery.
Configure Host Access to a Storage Center
1.
For Windows and Linux servers, click the Configure this host to access a Storage Center link
and log in to the Storage Center.
For VMware ESXi servers, click Configure VMware vSphere to access a Storage Center.
2. Follow the steps in the wizard to configure the host to access the Storage Center and configure
best practices for performing I/O.
When the host configuration is complete, use the Storage Manager Client to create and map
volumes.
