Description
Dual Controller Design
The dual-controller design of the MD1220 Dell Power Vault SAS Storage Array provides redundancy and fault tolerance, which helps to ensure the availability of the storage array.
The MD1220 has two controllers, each of which has its own processor, memory, and connectivity to the drives. The controllers work together to provide access to the drives, and if one controller fails, the other can take over without any interruption in service. This means that the storage array can continue to operate even if one of the controllers fails.
In addition, the dual-controller design can improve performance by allowing for load balancing between the controllers. This means that data can be accessed and processed more efficiently, which can help to improve overall system performance.
High Storage Capacity
The MD1220 Dell Power Vault SAS Storage Array provides high storage capacity in a compact form factor. It can support up to 24 2.5-inch SAS or SSD drives, providing a total capacity of up to 28.8 terabytes (TB) of storage (assuming each drive has a capacity of 1.2 TB).
The high storage capacity of the MD1220 can be useful for organizations that need to store large amounts of data in a compact space. This is particularly important for data-intensive applications such as databases, virtualization, and media storage, where high storage capacity is critical.
Additionally, the MD1220 allows users to add or remove drives without disrupting system operation, which can help to simplify maintenance and scalability. The storage array is designed to support hot-swappable drives, which means that failed or degraded drives can be replaced while the storage array is still running.
High-Speed Connectivity
The MD1220 Dell Power Vault SAS Storage Array supports high-speed connectivity with 6Gbps SAS connectivity. This provides fast data transfer rates between the storage array and the server, which can help to ensure that data can be accessed quickly and efficiently.
The high-speed connectivity of the MD1220 is particularly important for data-intensive applications that require fast access to data. This includes applications such as databases, virtualization, and media storage, where the speed of data access is critical to performance.
In addition, the MD1220 supports SAS expanders, which can be used to connect multiple storage arrays together for increased capacity and performance. This allows users to scale their storage solution as their needs grow, without sacrificing performance.
