Troubleshooting Hard Drives, 296 | Dell MD3600f, MD3620F instruction

•If both LEDs for any given FCIN port are unlit, see "Troubleshooting Array and Expansion Enclosure Connections" on page 297.

a Turn off the server, storage arrays, and expansion enclosures.

b Reseat the RAID controller module and reconnect cables on the storage array and the server.

c Restart the storage array and wait until the array is fully booted. d Turn on the server.

e Recheck the LEDs of the affected port(s). Replace the fiber optic cables of any port(s) where both LEDs are unlit.

NOTE: The SAS OUT status LED should be green.

If the problem is not resolved, see "Getting Help" on page 303.

Troubleshooting Hard Drives

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.

1Check the storage array profile to ensure that the most current version of the firmware is installed. For more information see the Support Matrix at support.dell.com/manuals.

2Remove the hard drive from the system. See "Removing a Hard Drive" on page 224.

NOTE: You must ensure that you check the hard drive indicators before removing the faulty hard drive from the system.

3Check the hard drives and the backplane to ensure that the connectors are not damaged.

4Reinstall the hard drive.

5If the problem is not resolved, replace the failed hard drive.

If the problem persists, see "Troubleshooting Loss of Communication" on page 289, "Troubleshooting an SFP Transceiver" on page 289, or "Getting Help" on page 303.

MD3620F, MD3600f specifications

Dell's MD3620F and MD3600F storage arrays are designed for businesses seeking dependable, high-performance storage solutions tailored to meet the demands of modern data management. These models offer a blend of scalability, efficiency, and advanced features, making them well-suited for a range of applications, from virtual environments to critical database operations.

One of the primary features of the MD3620F and MD3600F is their support for a hybrid storage architecture. This approach allows organizations to combine flash storage with traditional hard disk drives (HDDs) to optimize performance and cost. The MD3620F focuses heavily on all-flash configurations, delivering exceptional speed and lower latency, ideal for I/O-intensive workloads.

Scalability is another hallmark of these storage solutions. The MD3600F allows users to scale up to 120 drives, providing robust capacity to meet growing data needs. The MD3620F is engineered for environments where data availability and speed are paramount, with support for high IOPS (Input/Output Operations Per Second) and consistent performance under stress.

In terms of data management, both systems integrate with Dell’s proprietary software, which enhances operational efficiency through features like automated tiering. This technology optimizes data placement between different storage types based on access frequency, ensuring that hot data is readily available while reducing costs associated with less critical data.

Reliability is crucial for businesses that depend on their storage systems. The MD3620F and MD3600F come equipped with advanced data protection mechanisms, such as RAID support, which safeguards against data loss, and snapshot capabilities that provide point-in-time copies of data. Moreover, these solutions include hot-swappable components, ensuring minimal downtime for maintenance and repairs.

Connectivity is also a strong suit of these storage arrays. They support multiple connectivity options, including SAS and iSCSI, allowing for flexible integration into existing IT infrastructures. This adaptability enhances their appeal to a wide range of enterprise environments.

In summary, the Dell MD3620F and MD3600F stand out as robust storage solutions with a combination of hybrid and all-flash configurations, scalability, advanced data management tools, and enhanced reliability features. These characteristics make them ideal for organizations looking to enhance their data storage capabilities while maintaining high performance and efficiency.
