Signs your network needs reworking
A network is often built up piece by piece: a switch added in a hurry, a server forgotten in a cupboard. The day the management software freezes, the business stops.
- Slowdowns at peak hours Shared files, management software and video calls can no longer keep up.
- Poorly placed Wi-Fi No signal in the meeting room, devices dropping off the network on the loading docks.
- An unreadable rack Unlabelled cables, no up-to-date plan.
- Uncertain backups No one knows where the copies are or whether they have been tested.
- Access out of your hands It is held by a former provider or an employee who has left.
SADIS, a Moroccan company with its registered office in Laâyoune and an operational office in Casablanca, installs and upgrades SME infrastructure. We also work on software and ERP systems: if an incident occurs, you have a single point of contact.
Network audit and assessment
The network audit starts with an inventory of what is actually there: racks, switches, access points, servers, NAS, UPS units and cabling. We record the logical architecture (addressing, network separation, Internet and remote access), throughput, bottlenecks, poorly covered areas, end-of-life equipment and data that is not backed up.
You receive a written report and a list of works ranked by priority. Often, reconfiguring what is already in place is enough, before buying anything. This audit is free and comes before any quote.
Cabling, VLANs and switching
You replace a switch; you rarely re-cable a building. Structured cabling connects each outlet, labelled and tested, to the patch rack, with spare capacity for the future. The rack is labelled and protected by a UPS.
Switches are configured with VLANs: workstations, servers, guests, telephony, video surveillance and production each have their own network. An incident no longer spills over from one segment to another, and the rules for traffic between segments are written down and checked.
Fibre optics and cameras fall under low-voltage systems and video surveillance.
Professional Wi-Fi 6 and 6E
Professional Wi-Fi is judged by its stability wherever people work. In offices, the challenge is user density; in a warehouse or factory, it is distance, metal racking and concrete.
We place access points based on an on-site survey. Wi-Fi 6 or 6E is managed from a single console, handheld terminals move from one access point to another without losing their session, and the guest network stays separate. The vendor (Cisco, MikroTik, Ubiquiti, Aruba) is chosen according to what is already installed.
Servers, storage and backup
- Servers Windows Server, Linux and Active Directory to centralise accounts and permissions.
- Virtualisation Hyper-V, VMware or Proxmox consolidate servers onto fewer machines, which are easier to back up.
- NAS storage Synology shares per department, with clear permissions, snapshots and replication.
- Cloud backup One copy on site, one off site, and restores tested regularly.
An exposed NAS or a backup reachable from every workstation will not withstand ransomware: this part of the work ties in with cybersecurity.
Site interconnection and remote access
Head office, warehouse and branch need to work as a single site. We connect them by VPN, without exposing the management software, files or telephony to the Internet. Remote staff have named, revocable access, protected by multi-factor authentication (MFA).
A larger network can rely on OSPF or BGP, MPLS links, SD-WAN across several Internet links and quality of service (QoS).
IP telephony
IP telephony runs over the IT network: we deploy a 3CX or FreePBX IP PBX, based on the SIP protocol, with Grandstream or Yealink handsets. Calls travel on a dedicated VLAN and are given priority through QoS. A single switchboard serves several sites connected by VPN, and desk phones, softphones and mobiles share the same number.
Upgrades without downtime
A production site cannot afford to lose its network for a day. The cutover plan is written in advance and new equipment is prepared in parallel. The cutover is done zone by zone, in the evening or at the weekend if necessary, with a rollback plan and critical points checked before work resumes.
Monitoring, documentation and deliverables
Monitoring flags a full disk, a failed backup or an access point dropping out before users notice. Workstation follow-up is covered by IT fleet maintenance.
Every installation is delivered with as-built documentation (DOE): cabling plans, diagrams, labelling register and operating documentation. A joint acceptance report, drawn up with you, closes the works. Administrator access is in your name: you remain free to change providers.
A reference engagement
Case study
Valdeme Maroc, the Moroccan subsidiary of a French industrial group, entrusted us with overhauling its IT environment: redesign of the wired network and Wi-Fi, NAS storage, monitoring, access security, then user training. This foundation made its migration to Microsoft 365 possible, as described in the case study of this industrial subsidiary.
The founders spent six years on freelance assignments within large French industrial groups before founding SADIS in Morocco.
How an engagement runs
- Initial discussion Your premises, your workstations, your constraints.
- On-site audit Inventory, measurements, Wi-Fi survey and priorities.
- Proposal A precise scope and a cutover plan.
- Installation In stages, with checks.
- Handover Plans and access, in your name.
- Follow-up Monitoring, maintenance and upgrades.
