What a SAN Is
A Storage Area Network is a dedicated high speed network that connects many servers to shared block storage arrays. To each server, SAN capacity looks like a local disk, but behind the scenes the array pools drives, applies RAID, caches hot data and replicates to partner systems. SANs are the standard foundation for virtualisation clusters and demanding databases in enterprise data centers.
Why Enterprises Choose SAN
- High performance block access over Fibre Channel or iSCSI
- Central pool of capacity allocated to servers on demand
- Array features such as snapshots, thin provisioning and replication
- Enables live virtual machine migration and high availability clusters
- Scales to hundreds of terabytes without touching individual servers
Who Needs a SAN
Organisations running VMware or Hyper-V clusters, transactional databases such as Oracle, SQL Server or SAP HANA sidecar systems, and any environment where multiple servers must share fast resilient storage are natural SAN customers. If you operate more than four or five production servers with growing data, a SAN usually pays for itself in manageability and uptime.
Cost Reality
A SAN involves arrays, switches, host adapters and skills, so entry costs in India typically start in the range of several lakhs and scale with capacity and performance tier. Our job is to size it honestly - many clients need a modest hybrid array, not the flagship model a vendor brochure suggests.
Our Engagement
Through assessment we capture IOPS, latency and growth data from your live systems. The proposal compares at least two vendor options with five year cost of ownership. Implementation covers fabric design, zoning, multipathing, array setup and migration. Support provides health checks, firmware planning and expansion advice.
Practical Guidance
Insist on redundant fabrics end to end, keep firmware within vendor support matrices, and monitor latency, not just capacity. Contact us via app.techguru.co.in or +91-8800567676 for a SAN readiness review.
