1. SAN/NAS

SAN (Storage Area Network) is a high-speed fabric that exposes consolidated block storage to hosts, perfect for big transactional workloads and latency-sensitive apps.

NAS (Network Attached Storage) serves files over the network to many clients from a centralized appliance, simplifying sharing and permissions for heterogeneous environments.

A Storage Administrator wrangles both: SAN for finely carved, performant block LUNs with multipathing and zoning; NAS for straightforward file shares with snapshots, quotas, and directory services integration.

Why It's Important

SAN/NAS centralizes storage control, hardens security, and scales without drama. One place to tune, one place to protect, many places to serve. Uptime and speed live here.

How to Improve SAN/NAS Skills

Trim waste, chase latency, and keep the plumbing clean:

1. Monitor relentlessly: Track IOPS, latency, queue depth, cache hit ratio. Set alerts before users feel pain.

2. Stay current: Apply controller, drive, and switch firmware/software updates on a planned cadence.

3. Tune the layout: Choose RAID levels per workload, align stripe sizes, right-size volumes, and enable multipathing with correct policies.

4. Tier smartly: Blend SSD for hot data, HDD for cold, and let automated tiering move blocks where they belong.

5. Reduce data: Turn on deduplication and compression where beneficial. Verify post-process vs. inline behavior.

6. Harden resilience: Snapshots, replication, and tested runbooks. Practice failover, not just plan it.

7. Optimize the network: Segment with VLANs, apply QoS, consider jumbo frames for iSCSI/NFS, and validate DCB for iSCSI/NVMe over TCP where supported.

8. Secure end to end: Encrypt at rest, prefer encrypted protocols in-flight (SMB signing/enc, NFS over Kerberos), and enforce least-privilege access.

Do these well and SAN/NAS behaves—fast, predictable, and quiet.
