SANtricity express configuration manuals ( CA08872-012 )

Assumptions (ETERNUS AB/HB series and Linux)

The Linux express method is based on the following assumptions:

Component Assumptions

Hardware

  • You have used the Installation and Setup Instructions included with the controller shelves to install the hardware.

  • You have connected cables between the optional drive shelves and the controllers.

  • You have applied power to the storage system.

  • You have installed all other hardware (for example, management station, switches) and made the necessary connections.

  • If you are using NVMe over Infiniband, NVMe over RoCE, or NVMe over Fibre Channel, each ETERNUS AB3100, ETERNUS AB5100, ETERNUS AB6100 or ETERNUS HB5100/HB5200 controller contains at least 32 GB of RAM.

Host

  • You have made a connection between the storage system and the data host.

  • You have installed the host operating system.

  • You are not using Linux as a virtualized guest.

  • You are not configuring the data (I/O attached) host to boot from SAN.

Storage management station

  • You are using a 1 Gbps or faster management network.

  • You are using a separate station for management rather than the data (I/O attached) host.

  • You are using out-of-band management, in which a storage management station sends commands to the storage system through the Ethernet connections to the controller.

  • You have attached the management station to the same subnet as the storage management ports.

IP addressing

  • You have installed and configured a DHCP server.

  • You have not yet made an Ethernet connection between the management station and the storage system.

Storage provisioning

  • You will not use shared volumes.

  • You will create pools rather than volume groups.

Protocol: FC

  • You have made all host-side FC connections and activated switch zoning.

  • You are using our-supported FC HBAs and switches.

Protocol: iSCSI

  • You are using Ethernet switches capable of transporting iSCSI traffic.

  • You have configured the Ethernet switches according to the vendor’s recommendation for iSCSI.

Protocol: SAS

  • You are using our-supported SAS HBAs.

Protocol: iSER over InfiniBand

  • You are using an InfiniBand fabric.

Protocol: SRP over InfiniBand

  • You are using an InfiniBand fabric.

Protocol: NVMe over InfiniBand

  • You have received the 100G or 200G host interface cards in an EF300, EF600, EF570, or E5700 storage system pre-configured with the NVMe over InfiniBand protocol or the controllers were ordered with standard IB ports and need to be converted to NVMe-oF ports.

  • You are using an InfiniBand fabric.

Protocol: NVMe over RoCE

  • You have received the 100G or 200G host interface cards in an EF300, EF600, EF570, or E5700 storage system pre-configured with the NVMe over RoCE protocol or the controllers were ordered with standard IB ports and need to be converted to NVMe-oF ports.

Protocol: NVMe over Fibre Channel

  • You have received the 32G host interface cards in an EF300, EF600, EF570, or E5700 storage system pre-configured with the NVMe over Fibre Channel protocol or the controllers were ordered with standard FC ports and need to be converted to NVMe-oF ports.

These express method instructions include examples for SUSE Linux Enterprise Server (SLES) and for Red Hat Enterprise Linux (RHEL).
