What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.

What is SAN Storage?

Storage Area Network (SAN) storage is a specialized network that provides consolidated, block-level data storage access. Unlike direct-attached storage (DAS) or network-attached storage (NAS), SAN storage is designed to handle large amounts of data with high throughput and low latency. It connects various storage devices with servers, so the operating system views the storage as a local device. SANs are typically used in environments where performance and scalability are critical.

SAN Storage vs. Other Solutions

Performance and Scalability

  • DAS (Direct-Attached Storage): DAS is storage directly attached to the server or computer. It's simple and cost-effective but needs more scalability. You must physically add more drives to the server if you need more storage.
  • NAS (Network-Attached Storage): NAS provides file-based storage over a network. It's great for file sharing and is relatively easy to set up. However, NAS can face performance bottlenecks with heavy data usage.
  • SAN Storage: SAN offers high performance and excellent scalability. It separates storage from servers and networks, reducing performance bottlenecks and allowing you to pool and manage storage resources centrally.

Reliability and Flexibility

SAN storage is inherently more reliable and flexible. It supports various data backup, recovery, and archiving solutions. Its architecture allows for easy expansion, making it a go-to choice for businesses anticipating growth in data needs.

Benefits of SAN Storage


One of the biggest advantages of SAN storage is its scalability. As your data needs grow, you can expand your SAN storage without disrupting existing systems. This makes it ideal for businesses that foresee an increase in data usage.


SANs are designed to handle large amounts of data with high speed and low latency. This is crucial for applications like databases, transaction processing, and big data analytics, where quick data retrieval is vital.

High Availability and Disaster Recovery

SANs offer features like redundancy and failover capabilities, ensuring high availability. They are also conducive to implementing robust disaster recovery plans, as data can be replicated across multiple sites.

Improved Data Management

With SAN storage, data management becomes more centralized and efficient. It simplifies tasks like archiving, backup, and restoration. Centralized management also means better utilization of storage resources and reduced administrative overhead.

Applications and Scenarios for SAN Storage

Large Enterprises

Large businesses with extensive databases and the need for high-speed data access typically benefit the most from SAN storage. Industries like finance, healthcare, and e-commerce, where data access speed is critical, often rely on SANs.

Data Centers

Data centers, where managing large volumes of data efficiently and reliably is crucial, often use SANs. They provide the flexibility and scalability needed in such environments.

High-Performance Computing

SANs are ideal for high-performance computing scenarios where multiple processors require fast access to large volumes of data. This is common in scientific research, engineering, and financial modeling.

Virtualized Environments

In virtualized environments, where multiple virtual machines are running on physical servers, SANs provide efficient, centralized storage solutions. They allow for better resource allocation and management.
