NAS, SAN and object storage solutions

NAS SAN object storage_header_V1

 Modern IT environments require flexible, scalable, and high-performance storage solutions to meet diverse application and data demands. SAN, NAS, and Object Storage each play a critical role in supporting enterprise workloads  and understanding their unique strengths helps customers design optimal infrastructure.

Storage area network (SAN)

Key Reasons for Use:

  • High Performance for mission-critical applications:
    SANs deliver low-latency, high-throughput block-level access ideal for databases, ERP systems and transactional workloads.
  • Centralised storage management:
    SANs allow centralized control over storage resources, improving efficiency and simplifying provisioning.
  • Scalability and redundancy:
    Fibre Channel and iSCSI SANs offer robust scalability and high availability for large-scale deployments.
  • Advanced Features:
    SANs support features like snapshots, replication and tiering, essential for enterprise-grade resilience.

Network attached storage (NAS)

Key Reasons for Use:

  • File-level access for collaboration:
    NAS provides shared access to files across users and applications, making it ideal for home directories, media and office documents.
  • Ease of deployment and management:
    NAS systems are simple to install and manage, often requiring minimal IT overhead.
  • Integration with applications:
    NAS supports protocols like NFS and SMB, enabling seamless integration with operating systems and productivity tools.
  • Cost-Effective Storage:
    NAS is often more affordable for mid-tier workloads and departmental storage needs.

Object storage

Key Reasons for Use:

  • Scalability for unstructured data:
    Object storage is designed to scale horizontally, making it ideal for storing massive volumes of unstructured data like images, videos, backups and logs.
  • Metadata-rich architecture:
    Each object includes metadata, enabling advanced indexing, search and data management capabilities.
  • Cloud-Native Compatibility:
    Object storage supports RESTful APIs and integrates easily with cloud platforms and modern applications.
  • Durability and cost efficiency:
    Object storage offers high durability with erasure coding and is optimized for long-term, low-cost data retention.
