What DAS Is
Direct Attached Storage is storage connected directly to a single server without a network in between - internal drives, external disk shelves linked by SAS cables, or NVMe devices inside the chassis. Because there is no network hop, DAS delivers the lowest latency and the simplest management of any storage architecture, at the lowest cost per terabyte.
Strengths of DAS
- Excellent performance since data travels a direct path
- Lowest entry cost - no switches, fabric licences or specialist skills
- Simple to deploy; a disk shelf can be live within hours
- Predictable behaviour with no shared resource contention
Limitations to Understand
- Capacity is captive to one server and cannot be pooled
- No built in sharing - other servers cannot use spare space
- Scaling beyond a few shelves becomes awkward
- High availability requires application level clustering rather than storage features
Who Should Use DAS
DAS suits single application servers such as a dedicated database host, backup targets that ingest large nightly streams, video surveillance recorders, and branch offices with one or two servers. Many SMBs in India run happily on well configured DAS with RAID protection and disciplined backup, at a fraction of SAN cost.
How Tech Guru Helps
Following our standard engagement, the assessment confirms whether DAS genuinely fits or whether growth will strand you within a year. The proposal specifies enclosure, disk types, RAID layout and controller options with INR pricing. Implementation includes cabling, RAID configuration, filesystem tuning and burn in testing. Support covers disk failure handling, capacity monitoring and upgrade planning.
Practical Guidance
Always configure RAID with at least one hot spare, enable email alerts on the controller, and remember that RAID is not backup - a deleted or encrypted file is faithfully deleted or encrypted on every disk in the array.
