1 About the SCv2080 Storage System The SCv2080 storage system provides the central processing capabilities for the Storage Center Operating System (OS) and management of RAID storage. The SCv2080 storage system holds the physical drives that provide storage for the Storage Center. If additional storage is needed, the SCv2080 also supports a single SC180 expansion enclosure.
Figure 1. SCv2080 without an Expansion Enclosure • An SCv2080 storage system with one SC180 expansion enclosure Figure 2. SCv2080 with One Expansion Enclosure 1. SC180 expansion enclosure 2. SCv2080 storage system Storage Center Replication Storage Center sites can be collocated or remotely connected and data can be replicated between sites. Storage Center replication can duplicate volume data to another site in support of a disaster recovery plan or to provide local access to a remote data volume.
• iSCSI: Hosts, servers, or Network Attached Storage (NAS) appliances access storage by connecting to the storage system iSCSI ports through one or more Ethernet switches. Connecting host servers directly to the storage system, without using Ethernet switches, is not supported. When replication is licensed, the SCv2080 can use the front-end iSCSI ports to replicate data to another Storage Center. • SAS: Hosts or servers access storage by connecting directly to the storage system SAS ports.

Press the lock-release buttons inward and use your body to push the drawer toward the chassis until the locks disengage. c.
3 Connect the Front-End Cabling Front-end cabling refers to the connections between the storage system and external devices such as host servers or another Storage Center. Front‐end connections can be made using Fibre Channel, iSCSI, or SAS interfaces. Dell recommends connecting the storage system to host servers using the most redundant option available.
Fault Domains Fault domains group front-end ports that are connected to the same network. Ports that belong to the same fault domain can fail over to each other because they have the same connectivity. Dell recommends configuring at least two connections from each storage controller to each fault domain. Multipath I/O MPIO allows a server to use multiple paths for I/O if they are available. MPIO software offers redundancy at the path level.
Connecting to Fibre Channel Host Servers Choose the Fibre Channel connectivity option that best suits the front‐end redundancy requirements and network infrastructure. Preparing Host Servers Install the Fibre Channel host bus adapters (HBAs), install the drivers, and make sure that the latest supported firmware is installed. About this task • Contact your solution provider for a list of supported Fibre Channel HBAs.

Using SFP+ Transceiver Modules An SCv2080 storage system with 16 Gb Fibre Channel storage controllers uses short range small-form-factor pluggable (SFP+) transceiver modules. Figure 42. SFP+ Transceiver Module with a Bail Clasp Latch The SFP+ transceiver modules are installed into the front-end ports of a storage controller. Fiber-optic cables are connected from the SFP+ transceiver modules in a storage controller to SFP+ transceiver modules in Fibre Channel switches.
Steps 1. Position the transceiver module so that the key is oriented correctly to the port in the storage controller. Figure 43. Install the SFP+ Transceiver Module 1. 2. SFP+ transceiver module 2. Fiber-optic cable connector Insert the transceiver module into the port until it is firmly seated and the latching mechanism clicks. The transceiver modules are keyed so that they can only be inserted with the correct orientation.
CAUTION: Touching the end of a fiber-optic cable damages the cable. Whenever a fiber-optic cable is not connected, replace the protective covers on the ends of the cables. 2. Open the transceiver module latching mechanism. 3. Grasp the bail clasp latch on the transceiver module and pull the latch out and down to eject the transceiver module from the socket. 4. Slide the transceiver module out of the port. Figure 44. Remove the SFP+ Transceiver Module 1. SFP+ transceiver module 2.
Steps 1. Starting with the top edge of the label, attach the label to the cable near the connector. Figure 45. Attach Label to Cable 2. Wrap the label around the cable until it fully encircles the cable. The bottom of each label is clear so that it does not obscure the text. Figure 46. Wrap Label Around Cable 3. Apply a matching label to the other end of the cable.
NOTE: Do not install iSCSI HBAs or network adapters from different vendors in the same server. b. Install supported drivers for the HBAs or network adapters and make sure that the HBAs or network adapter have the latest supported firmware. c. Use the host operating system to assign IP addresses for each iSCSI port. The IP addresses must match the subnets for each fault domain. CAUTION: Correctly assign IP addresses to the HBAs or network adapters.
