Data storage
SilkWay manage and monitor data storage within a data center, on site. It includes all IT assets that store, retrieve, distribute, back up or archive computer data and applications inside the data center facility. Whereas “IT storage” refers to both on-site and off-site storage assets, “data center storage” refers specifically to on-site assets. These may include hard disk drives, tape drives, direct-attached storage (DAS) devices, storage and backup management software utilities, storage networking technologies such as storage area networks (SAN), network attached storage (NAS) and redundant array of independent disks (RAID) devices. Data center storage also includes the policies and procedures that govern data storage and retrieval such as data collection and distribution, access control, storage security, data availability, storage quotas, backup schedules, data retention schedules, and so on. In financial, medical and other highly regulated industries, data center storage must comply with government and industry regulations for data storage, information privacy and data security.

THE RIGHT POSSIBILITIES
At SilkWay Development, we innovate to protect, connect and power a sustainable digital world. Our corporate Sustainability Program is a set of environment, social and governance (ESG) initiatives designed to positively impact our planet and people.
Direct-Attached Storage
As the name suggests, DAS is a storage configuration in which HDDs or SSDs are attached directly to a computer, rather than connecting via a network such as Ethernet, Fibre Channel, or InfiniBand. DAS typically refers to HDDs or SSDs. Other storage types, such as optical or tape drives, can theoretically be considered DAS if they connect directly to the computer, but references to DAS nearly always refer to HDDs or SSDs, including those in this article.
NAS is a file-level storage device that enables multiple users and applications to access data from a centralized system via the network. With NAS, users have a single access point that is scalable, relatively easy to set up, and cheaper than options such as SAN. NAS also includes built-in fault tolerance, management capabilities, and security protections, and it can support features such as replication and data deduplication.
A SAN is a dedicated, high-speed network that interconnects one or more storage systems and presents them as a pool of block-level storage resources. In addition to the storage arrays themselves, a SAN includes multiple application servers for managing data access, storage management software that runs on those servers, host bus adapters (HBAs) to connect to the dedicated network, and the physical components that make up that network’s infrastructure, which include high-speed cabling and special switches for routing traffic.
For many organizations, traditional DAS, NAS, and SAN solutions properly sized and configured will handle their workloads with ease. If that’s insufficient, they might consider newer technologies that enhance these core configurations, such as converged or hyperconverged infrastructures. Today’s organization can also take advantage of such technologies as cloud storage, object storage, or software-defined storage, as well as the various forms of intelligent storage that are taking hold of the enterprise.
