- **Long Duration Storage:** - This could mean either: - **Long-term storage** (archiving data for months/years). - Or **handling heavy/extensive workloads** over long periods (e.g., high-speed data access and processing like in AI/ML tasks). - **NVMe (Non-Volatile Memory Express):** - A high-speed storage interface that allows fast data transfer between your computer and SSDs. - Great for tasks that need fast access and high performance (like AI training or video rendering). - **Not ideal for long-term archival** because it's more expensive and optimized for speed rather than cost/storage density. - **Spindle or HDD (Hard Disk Drive):** - Traditional mechanical drives that are slower than NVMe but **cheaper and better for long-term, large-capacity storage**. - Easier to scale up if you're storing lots of data without needing fast access. - **High-performance storage solutions (like DDN or Weka):** - These are advanced storage systems designed for high-speed access to massive datasets. - Commonly used in AI, scientific computing, and large enterprise applications. - **Bare Metal Hardware:** - Physical servers or computers without any software installed. - You can install any operating system or software you like (such as your preferred storage management software). - **Ceph / Lustre:** - Open-source software platforms for managing large-scale storage systems. - Ceph is popular for object, block, and file storage. - Lustre is often used in high-performance computing (HPC) environments.
