Enterprise storage systems often use RAID for scalable data protection, performance and can use fast connections such as Fiber Channel or iSCSI.

RAID (Redundant Array of Inexpensive Disks) is a method of using multiple hard drives to provide data protection, performance, and scalability in an enterprise storage system. Fiber Channel or fast connections are used for communication between the storage system and other parts of the network. Other options such as SSD (Solid State Drive), SuperSD, and iSCSI (Internet Small Computer System Interface) are also used in enterprise storage systems for various purposes.

RAID arrays can be configured in different ways to provide varying levels of data protection and performance, such as RAID 0 for performance, RAID 1 for data protection through mirroring, RAID 5 for data protection through parity, and RAID 6 for double-parity protection. Scalability is achieved by adding more hard drives to the RAID array as needed, up to the maximum system capacity. This allows for growth in data storage needs without the need for a complete system upgrade. Other storage solutions such as SSDs, SuperSDs, and iSCSI offer similar benefits, but may have different trade-offs in terms of performance, cost, and reliability, so it's important to choose the right storage solution based on specific needs and requirements.

The Amazon EC2 feature that ensures instances will not share a physical host with instances from any other AWS customer is called Amazon EC2 Dedicated Hosts.

Amazon EC2 Dedicated Hosts are physical servers with AWS infrastructure that are dedicated to one AWS customer. This means that when you launch instances on a Dedicated Host, you have the entire physical server to yourself, and your instances are isolated from instances of other AWS customers. This provides you with additional visibility and control over the placement of your instances, and can be useful in certain regulatory and compliance scenarios where instances must be physically isolated. Additionally, because you have control over the physical server, you can choose to use your own licenses for applications and ensure that your instances are running on the specific hardware you require.

With Amazon EC2 Dedicated Hosts, you have the ability to use your own custom licensing, and you have complete control over the placement of instances on the host, which helps ensure that your instances run on the hardware you want, and helps you meet compliance and regulatory requirements.
