About Mastertech MEP Consultants
Mastertech MEP Consultants is a Mumbai-based Mechanical, Electrical, and Plumbing (MEP) design and consulting firm handling comprehensive building engineering services across Maharashtra and beyond. Their scope covers Air-Conditioning and Ventilation systems, Electrical (HT/LT) design, Plumbing and Water Management, Fire Fighting and Fire Annunciation systems, Public Address systems, Water Treatment Plants, Solar Energy, and MOEF compliance — the full spectrum of building services engineering for residential, commercial, and institutional projects.
An MEP consulting office generates a very specific kind of data: large AutoCAD drawings, MEP coordination models, structural overlays, BIM files, equipment specification sheets, and client-specific project documentation — often running into hundreds of gigabytes per project. These files are the firm's deliverables, their intellectual property, and their legal record. Losing them is not a recoverable situation.
Mastertech MEP needed a centralised, secure, and fast network-attached storage system that their engineering teams could access reliably from within the office network — with hardware encryption protecting client project data at rest, and hot-swappable drives so a disk failure doesn't interrupt project delivery. Layerix Networking Experts was engaged to specify, supply, install, configure, and commission the complete NAS storage infrastructure for their main office in Mumbai.
The Challenge — CAD Files Don't Belong on a USB Drive or Someone's Laptop
MEP consulting firms across Maharashtra typically run one of two storage models — both of which eventually cause serious problems:
- Individual workstation storage: Each engineer stores project files on their own laptop or desktop. Collaboration means sending files over email or WhatsApp. Version control is whoever saved last. If a laptop dies, so does the project archive. This is how most MEP firms in Mumbai start — and it works until it doesn't.
- External HDDs or USB drives: Slightly better than workstation storage, but USB drives fail, get misplaced, and offer zero network access for multiple simultaneous users. A 3D MEP coordination model can be 2GB+ — copying it to a USB to share across the office is a workflow that kills productivity.
- Cloud storage only: Cloud storage is excellent for small files. For large CAD drawings and MEP models, upload and download times on Indian internet connections make cloud-first workflows frustrating for large files. And cloud storage for client data requires careful evaluation of where data actually resides.
- No hardware encryption on client project data: MEP consultants handle confidential building infrastructure designs for clients — electrical schematics, fire system designs, HVAC layouts. This data needs to be encrypted at rest, not just protected by a network share password.
The answer was a purpose-built network attached storage (NAS) system — fast enough for multiple concurrent users accessing large project files over the local network, with hardware encryption for data security, hot-swappable drives for maintenance without downtime, and enough raw storage capacity for the firm's current project archive with room to grow. Layerix specified the Synology DS225+ as the right platform and the Seagate IronWolf 4TB as the right drive — not because they were the cheapest option, but because they were the right choice for a 12×6 always-on NAS workload.
Why the Synology DS225+ — and Not a Generic NAS or Cloud?
The Synology DS225+ is a 2-bay NAS built specifically for the kind of office workload an MEP consulting firm generates. The Intel Celeron J4125 quad-core processor handles file serving, on-the-fly hardware encryption, and background drive health monitoring simultaneously — without throttling file transfer speeds under load. The 2.5GbE LAN port delivers nearly 3× the throughput of a standard 1GbE connection, which matters when multiple engineers are opening large CAD files from the same NAS concurrently. The hardware encryption engine means encryption and decryption happen in dedicated silicon — not in the CPU — so there's no performance penalty for keeping sensitive project data encrypted at rest.
The NAS vs cloud storage decision for an MEP firm comes down to file size and access speed. For files under 100MB, cloud works well. For large AutoCAD drawings, MEP BIM models, and multi-discipline coordination files, a local NAS with a 2.5GbE connection delivers consistently faster access than even the best Indian broadband internet connection — and the data never leaves the office network.
The Scope — Synology DS225+, IronWolf HDDs, Configured and Commissioned
Layerix Networking Experts specified, supplied, installed, configured, and commissioned the complete NAS storage system for Mastertech MEP's Mumbai office. Every decision — hardware platform, drive selection, network port usage, encryption policy, and share structure — was made for the specific context of an MEP consulting firm's data environment.
Synology DS225+ 2-Bay NAS — Intel Celeron J4125, Hardware Encryption ↗
Synology DiskStation DS225+ — Intel Celeron J4125 quad-core processor (2.0GHz base, 2.7GHz turbo), 2GB DDR4 non-ECC RAM with expansion slots to 6GB, hardware encryption engine, 3.5"/2.5" SATA drive bays with hot-swap support. The hardware encryption engine is the key specification for an MEP consulting firm: project drawings and client data are encrypted at rest without any CPU performance penalty. The quad-core processor handles concurrent file serving for multiple engineering workstations simultaneously.
2 × Seagate IronWolf 4TB NAS HDD — ST4000VN006, 6Gb/s SATA ↗
2 × Seagate IronWolf ST4000VN006 4TB NAS-specific hard drives — 6Gb/s SATA interface, IronWolf Health Management firmware, purpose-built for 12×6 always-on NAS workloads. Consumer desktop HDDs fail faster in NAS environments because they're not designed for the vibration, temperature, and continuous read/write cycles that a shared office file server generates. IronWolf drives are engineered specifically for this use case, with a 3-year warranty and NAS-optimised firmware that communicates drive health to Synology DSM.
2.5GbE LAN + 1GbE RJ45 + USB 3.2 Gen 1 Port ↗
The Synology DS225+ provides both a 2.5GbE LAN port and a standard 1GbE RJ45 port — the 2.5GbE port was configured as the primary network connection, delivering up to 312MB/s theoretical throughput to the office switch. The USB 3.2 Gen 1 port enables fast external backup to a USB HDD — a separate backup device ensures the NAS itself is not the only copy of critical project data.
Network Share Configuration — MEP Discipline Access Control ↗
Shared network folders configured on Synology DSM: separate shares for HVAC/Mechanical, Electrical, Plumbing, Fire, and Admin — with per-discipline user access permissions so engineers access only the project folders relevant to their scope. Project folders organised by client and project code. Hardware encryption enabled on the shared volume — data encrypted at rest, decrypted on access by authenticated users.
Hot-Swappable Drive Bays — Maintenance Without Downtime ↗
Both Seagate IronWolf drives installed in the DS225+'s hot-swappable bays. In the event of a drive failure, the failed drive can be removed and replaced without powering down the NAS — the Synology DSM RAID management automatically rebuilds the volume on the replacement drive. For an MEP consulting office running active project deliverables, zero-downtime maintenance is not optional.
Network Rack Installation & As-Built Documentation ↗
The Synology DS225+ was racked in the office network room with proper cable management — network cable dressed to the switch port, power connection labelled, and device position documented in the network room as-built. Port labels, IP address scheme, admin credentials, Synology DSM admin guide, Seagate IronWolf warranty registration, and share configuration reference delivered at handover. As-built documentation is not a luxury — it's what makes the system serviceable by any engineer, on any future date.
Three Phases — Specify Right, Install Right, Commission Right
A NAS storage deployment for a professional consulting firm isn't complicated — but the decisions made at specification stage determine whether the system serves the firm well for five years or causes headaches within six months. Layerix ran the Mastertech MEP deployment in three clean phases: assess and specify, install and configure, commission and document.
NAS vs Cloud. Which Drive. Which Configuration. Decided Before Any Hardware Was Ordered.
Layerix engineers assessed Mastertech MEP's current storage situation — where project files lived, how many concurrent users accessed them, the average size of their project deliverables (CAD drawings, MEP models, coordination sheets), and the network switch capability available. The NAS vs cloud storage evaluation was done based on actual file sizes and actual internet bandwidth — not theory. The verdict: a local NAS with 2.5GbE was the right answer for large project files. The Synology DS225+ was specified, the drive count and RAID mode confirmed, and the network share structure planned before any hardware was purchased.
Storage Requirements Assessment
Current project archive size measured, average new project data volume estimated, and growth trajectory calculated. Total usable storage requirement determined for the next 3-year planning horizon — informing the decision to start with 2 × 4TB IronWolf drives.
Network Switch Compatibility Check
Office switch port verified for 2.5GbE compatibility to maximise DS225+ throughput. Where a standard 1GbE switch was in place, the 1GbE RJ45 port was designated as the primary connection — with a note in the as-built for 2.5GbE upgrade path.
RAID Mode Selection
For a 2-bay NAS with Seagate IronWolf drives, Synology Hybrid RAID (SHR) or RAID 1 (mirroring) was configured — providing data redundancy so a single drive failure doesn't result in data loss. The usable capacity is one drive (4TB) with the second as mirror.
Share Structure Planning
Network share folder structure mapped to Mastertech MEP's engineering disciplines — Mechanical/HVAC, Electrical (HT/LT), Plumbing, Fire, and Administration — with user group permissions planned per discipline before installation.
The Right NAS. The Right Drives. The Right Network Rack Position.
With hardware specified and procured, Layerix engineers installed the Synology DS225+ in the Mastertech MEP office network room — properly racked with cable management, power labelled, and network connection to the switch verified before Synology DSM was configured. Both Seagate IronWolf ST4000VN006 drives were installed in the hot-swappable bays, RAID mode configured, and the volume encrypted using the DS225+'s hardware encryption engine.
Synology DS225+ Physical Installation
DS225+ positioned in the office network room with proper rack or shelf mounting, network cable dressed to the switch, power connected and labelled. Physical installation documented in the network room as-built — port number, IP address, and device location recorded.
Seagate IronWolf 4TB Drive Installation
Both Seagate IronWolf ST4000VN006 drives installed in the DS225+'s hot-swappable 3.5" bays. Drives detected by Synology DSM, drive health verified via IronWolf Health Management firmware report before volume creation.
Synology DSM Setup & Volume Creation
Synology DiskStation Manager (DSM) configured — system update applied, admin account secured, network interface settings confirmed (2.5GbE primary, 1GbE secondary), storage pool created with selected RAID mode, and shared volume formatted.
Hardware Encryption Engine — Volume Encryption
Shared volume encrypted using the DS225+'s dedicated hardware encryption engine — AES-256 encryption at rest. Encryption key managed through Synology DSM's key manager. Hardware encryption means no CPU performance penalty: file transfer speeds are identical whether encryption is enabled or not.
Shared Folders Configured. Users Enrolled. Files Accessible. Documented.
The final phase configured the shared folder structure for Mastertech MEP's engineering teams, set up per-discipline user access permissions, verified file access from each workstation on the office network, and delivered the complete documentation package. A properly documented NAS installation means any IT person — today or five years from now — can understand the system, change a user password, add a new folder, or replace a failed drive without calling anyone.
Shared Folder Structure — MEP Discipline Separation
Synology DSM shared folders created: Mechanical-HVAC, Electrical-HTLT, Plumbing-WM, Fire-FAS, Projects-Archive, and Administration. Per-folder permissions assigned to engineering user groups — engineers access only their discipline folders, reducing accidental overwriting of cross-discipline files.
User Accounts & Access Permissions
Individual user accounts created in Synology DSM for each engineer. Password policy enforced. Read/Write permissions assigned per user per shared folder. Admin account credentials documented separately in the secure handover pack.
File Access Verification — All Workstations
NAS access verified from every Windows workstation on the office network — mapped drive confirmed, file copy/write speed measured over the 1GbE/2.5GbE connection, and hardware encryption transparency verified (no performance impact). USB 3.2 Gen 1 external backup port tested with an external HDD.
As-Built Documentation & Handover Pack
Complete documentation delivered: IP address scheme (NAS IP, gateway, DNS), Synology DSM admin credentials (secured), shared folder map with permission matrix, RAID configuration reference, IronWolf HDD serial numbers and warranty registration, drive replacement procedure, and Synology DSM update policy guide.
The Outcome — A Mumbai MEP Firm's Project Files Are Now Safe, Shared, and Fast
When Layerix completed the Mastertech MEP deployment, the firm's Mumbai office had:
- Centralised project file storage: All MEP project drawings, CAD files, BIM models, and engineering documentation on one Synology DS225+ NAS — accessible from every office workstation over the local network, no USB drives or email attachments required.
- Hardware encryption at rest: Client project data — HVAC layouts, electrical schematics, fire system designs — encrypted using the DS225+'s AES-256 hardware encryption engine. No performance penalty. No compliance gap.
- Purpose-built NAS drives that won't fail early: Seagate IronWolf ST4000VN006 drives built for 12×6 NAS workloads — not consumer desktop drives repurposed into a server environment.
- Hot-swappable drives — zero-downtime maintenance: A drive failure doesn't mean downtime. Replace the failed drive while the NAS keeps running, and DSM rebuilds the RAID volume automatically.
- Full documentation: As-built, IP scheme, admin guide, permission matrix, and warranty records — the system is serviceable by anyone, today or five years from now.

Why MEP Consulting Firms in Maharashtra Need a Proper NAS Storage System
MEP design firms across Mumbai and Maharashtra are producing large, complex technical files every single day — AutoCAD drawings, MEP coordination overlays, equipment schedules, vendor submittals. These files are the firm's product, their legal record, and their intellectual property. Storing them on individual laptops or USB drives is a risk that most firms carry until the first serious data loss event. After that event, the cost of recovery — lost project files, client disputes, rework hours — far exceeds the cost of a properly specified NAS deployment.
The Synology DS225+ with Seagate IronWolf drives is the right NAS vs cloud storage answer for a professional MEP consulting office in Mumbai: fast local access over a 2.5GbE LAN connection, hardware encryption for client data protection, RAID 1 mirroring for drive failure resilience, and hot-swappable bays for zero-downtime maintenance. It's a network attached storage system designed around an engineering firm's actual data workflow — not a generic solution bolted on afterward.
For architecture and design firms, MEP consultants, and engineering companies across Maharashtra looking at their first NAS storage deployment — or replacing an existing system that isn't working — Layerix Networking Experts provides the full engagement: specification, procurement, rack installation, DSM configuration, user setup, and complete documentation. The same network rack installation and cable management standard Layerix applies to enterprise corporate deployments is applied to every office NAS installation — because the documentation that makes a system serviceable is as important as the hardware itself.
"An MEP firm's project files are their product, their legal record, and their reputation. A USB drive is not a storage strategy. A properly configured NAS with hardware encryption and RAID mirroring is."
