Storage arrays are critical part to storage networks, allowing the storage functions of the network to be completely separated from the LAN or WAN connecting all the devices within an organization. However, HDDs are cheaper, so they’re sometimes used in combination. This protects the data from loss if one of the disks fails, as all the backup copies are still available.Īn SSD storage array, also called a flash storage array, has the same basic storage array architecture as an HDD array but will operate much faster. For example, redundant arrays of independent disks (RAID) controllers are used to make copies of the same data across multiple hard disks. HDD storage arrays, or disk arrays, are commonly used in business environments for storage purposes and have excellent redundancy features to help protect data. In some cases, they use a combination of both so they can scale much more efficiently than the storage capacity of a collection of servers. Storage arrays keep storage separate from servers using a collection of hard disk drives (HDDs) or solid-state drives (SSDs). What Does Modern Data Center Architecture Look Like?īest Storage Array Monitor How Do Storage Arrays Work? I also review the key features of several of these top solutions, and explain why Storage Resource Monitor is my best pick due to its unified management system, performance optimization capabilities, and storage capacity forecasting features. In this guide, I discuss the basics of storage arrays, including what they are, how they work, common setups of data centers, and how monitoring tools can help improve array performance. The performance of storage arrays can be improved by using a high-quality management system to keep track of capacity, errors, and trends. Rather than store data on a server, storage arrays use multiple drives in a collection capable of storing a huge amount of data, managed by a central management system. A storage array, also called a disk array, is a data storage system for block-based storage, file-based storage, or object storage.
