PCI Errors

The storage array firmware can detect and only recover from PCI errors when the RAID controller modules are configured for redundancy. If a virtual disk uses cache mirroring, it fails over to its peer RAID controller module, which initiates a flush of the dirty cache.

Critical Conditions

The storage array generates a critical event if the RAID controller module detects a critical condition that could cause immediate failure of the array and/or loss of data. The storage array is in a critical condition if one of the following occurs:

•More than one fan has failed

•Any backplane temperature sensors in the critical range

•Backplane/power supply failure

•Two or more temperature sensors are unreadable

•Failure to detect or unable to communicate with peer port

NOTE: If both RAID controller modules fail simultaneously, the array cannot issue critical or noncritical event alarms for any array component.

When the array is under critical condition, its array status LED blinks amber.

Noncritical Conditions

A noncritical condition is an event or status that does not cause immediate failure, but must be corrected to ensure continued reliability of the storage array. Examples of noncritical events include the following:

•One power supply has failed

•One cooling fan has failed

•One RAID controller module in a redundant configuration has failed

•A battery has failed or has been removed

•A physical disk in a redundant virtual disk has failed

When the array is under noncritical condition, its array status LED blinks amber.

MD3200i, MD3220i specifications

The Dell MD3220i and MD3200i are part of Dell's extensive line of modular storage solutions, designed to support organizations in optimizing their data management and scalability requirements. These models offer reliable performance and flexible features, making them suitable for various workloads including virtualization, cloud storage, and disaster recovery.

One of the standout features of the MD3220i and MD3200i is their support for iSCSI storage networking. By utilizing the Internet Small Computer Systems Interface (iSCSI) protocol, these systems provide organizations with a cost-effective way to connect their storage over existing network infrastructure, enabling efficient data transfers and management.

Both models are equipped with dual controllers that ensure high availability and failover capabilities, which are crucial for meeting uptime requirements in mission-critical environments. The dual controllers also facilitate load balancing and increase overall system performance, as they allow multiple paths to the storage, enhancing I/O performance.

Scalability is another key characteristic of the MD3220i and MD3200i. These storage arrays can be expanded to meet growing storage demands, supporting up to 240TB of raw capacity with up to 16 additional expansion enclosures. This flexibility allows organizations to start with a smaller configuration and grow their storage capabilities without a complete overhaul of the existing infrastructure.

The units also support multiple disk types, including traditional spinning disks, solid-state drives (SSDs), and a combination of both. This versatility enables users to tailor storage configurations to their specific performance and budgetary needs. Furthermore, the systems feature advanced data management technologies such as snapshots and remote replication, providing essential tools for data protection.

With their ease of management, the MD3220i and MD3200i are designed for straightforward configuration and operation. The intuitive management interfaces allow IT professionals to monitor performance, configure storage, and manage data effectively, ensuring businesses can maintain optimal system availability.

In summary, the Dell MD3220i and MD3200i are robust, scalable, and versatile storage solutions that cater to diverse organizational needs. Their integrated technologies, such as iSCSI support, dual controller architecture, and advanced data management features, make them an ideal choice for modern data centers looking to enhance storage capabilities while ensuring reliability and performance.
