Choosing the right Storage Technology for Your Organization
IT Professionals has a post with some background information on the most common storage technologies that are currently available: NAS, SAN, DAN and iSCSI. If you’re running a small/medium seized business this may help you decide which one is best for you:
Although the need for storage is evident, it is not always clear which solution is right for your organization. There are a variety of options available, the most prevalent being direct-attached storage (DAS), network-attached storage (NAS) and storage area networks (SAN). Choosing the right storage solution can be as personal and individual a decision as buying a home. There is no one right answer for everyone. Instead, it is important to focus on the specific needs and long-term business goals of your organization. Several key criteria to consider include:
- Capacity – the amount and type of data (file level or block level) that needs to be stored and shared
- Performance – I/O and throughput requirements
- Scalability – Long-term data growth
- Availability and Reliability – how mission-critical are your applications?
- Data protection – Backup and recovery requirements
- IT staff and resources available
- Budget concerns
While one type of storage media is usually sufficient for smaller companies, large enterprises will often have a mixed storage environment, implementing different mediums for specific departments, workgroups and remote offices. In this paper, we will provide an overview of DAS, NAS and SAN to help you determine which solution, or combination of solutions, will best help you achieve your business goals.
Read the article explaining the differences and uses of:
- DAS: Ideal for Local Data Sharing Requirements
- NAS: File-Level Data Sharing Across the Enterprise
- SANs: High Availability for Block-Level Data Transfer
