Page 10: About This Guide
• AssuredSAN CLI Reference Guide CNC ports used for host connection AssuredSAN 6844/6854 models use Converged Network Controller (CNC) technology, allowing you to select the desired host interface protocol from the available Fibre Channel (FC) or Internet SCSI (iSCSI) host interface protocols supported by the system. -
Page 11: Hd Mini-Sas Ports Used For Host Connection
IMPORTANT: AssuredSAN 6844/6854 models ship with CNC ports initially configured for FC. When connecting CNC ports to iSCSI hosts, you must use the CLI (not the SMC orRAIDar) to specify which ports will use iSCSI. -

Page 51: Connecting Hosts
Cabling systems to enable use of the optional AssuredRemote™ feature—to replicate volumes—is yet another important cabling consideration. See Connecting two storage systems to replicate volumes on page 61. The 6844/6854 models can be licensed to support replication; whereas the 6544/6554 models do not support the feature. TIP: Table 5 on page 38 aligns product model numbers with 2U and 4U chassis form factors. -
Page 52: Fibre Channel Protocol
Each controller module provides four host ports designed for use with an FC SFP supporting data rates up to 16 Gbit/s. When configured with FC SFPs, 6844/6854 controller enclosures can also be cabled to support the optionally-licensed AssuredRemote replication feature via the FC ports (linear storage only). -

Controller failure in a single-controller configuration This subsection addresses a potential situation that might occur if a partner controller fails following failure of its peer controller. IMPORTANT: Transportable cache only applies to single-controller configurations. In dual-controller configurations, there is no need to transport a failed controller’s cache to a replacement controller because the cache is duplicated between the partner controllers (subject to volume write optimization settings). -

NOTE: Do not perform more than one step at a time. Changing more than one variable at a time can complicate the troubleshooting process. 1. Halt all I/O to the storage system (see Stopping I/O on page 77). 2. Check the host activity LED. If there is activity, halt all applications that access the storage system. -
Page 86: Replication Setup And Verification
Replication setup and verification After storage systems are cabled for replication, you can use the SMC (v3) or RAIDar (v2) to prepare to use the replication feature. Alternatively, you can use telnet to access the IP address of the controller module and access the replication feature using the CLI. -
