Based on the exhibit, a customer is using Virtual Port Mode. If the primary path for the controller on the `left` is disconnected while running an IOmeter test for a volume owned by the `left` controller, will the system survive failover?
Based on the exhibit, a customer is using Virtual Port Mode. If the primary path for the controller on the `left` is disconnected while running an IOmeter test for a volume owned by the `left` controller, will the system survive failover?
Virtual Port Mode is designed to handle failovers by redirecting the I/O through other available paths within the same domain. If the primary path for the controller on the left is disconnected, the Virtual Port Mode will move the virtual WWN to another physical port in the same domain, ensuring that the I/O operations continue without interruption.
Based on documented best practices, which options may need to be modified on a server QLogic HBA?
Based on documented best practices, 'LUNs Per Target' and 'Port Down Retry Count' are both settings that are commonly adjusted on QLogic HBA (Host Bus Adapter). 'Port Down Retry Count' helps in managing the reconnection attempts when a port goes down, and 'LUNs Per Target' specifies the maximum number of LUNs (Logical Unit Numbers) per target, which is essential for optimizing storage configurations.
To achieve redundancy, how many connections from the same SC Series controller are required per fault domain?
To achieve redundancy, a minimum of 2 connections from the same SC Series controller are required per fault domain. This ensures that if one connection fails, the system can continue to operate using the second connection, thus maintaining redundancy.
You are implementing a front-end connection in Legacy Port Mode on an SC4020 in a SAN with two iSCSI switches. What is the minimum number of port(s), per switch, that can be used by each controller?
In a SAN environment implementing front-end connections in Legacy Port Mode on an SC4020, each controller typically needs a minimum of two ports per switch to ensure redundancy and proper failover capabilities. This configuration helps maintain connectivity if one port or path fails, ensuring continuous operation and data access.
A customer is using an SC8000 array with three chained SC220 expansion enclosures on a single card. They need to expand its capacity by adding an SC280 enclosure. How should the new expansion enclosure be connected using a minimum number of chains?
To expand the capacity while minimizing the number of chains, the SC280 enclosure should be connected to a new chain on the same SAS I/O card. This ensures optimal performance and compatibility, as mixing SC280 enclosures with other types in the same chain is not recommended.
