Hardware maintenance in London —
4-hour engineer + parts, multi-vendor.
Servnet runs multi-vendor break-fix and post-warranty cover for kit installed across central London — Dell PowerEdge / PowerStore, HPE ProLiant / Alletra / Nimble, Cisco Catalyst / Nexus, NetApp ONTAP, Pure FlashArray, Lenovo ThinkSystem and EOSL legacy estates. Engineer + parts dispatched inside the M25 to a 4-hour standard SLA, with same-day Square Mile attendance for P1.
Why London hardware support is its own discipline
Most of the UK's biggest data centres sit inside the M25 — and the hardware in them runs the country's financial, legal and broadcast estate. London hardware maintenance is about being physically close, being fast, and knowing every vendor on the rack.
Telehouse, Equinix, VIRTUS, Global Switch — same-day reach
Servnet engineers attend Telehouse North / East / West, Equinix LD1–LD8, VIRTUS LONDON1–4, Global Switch London and Pulsant in central London inside a 4-hour SLA — DC access protocols, smart-hands escalations and badge management already worked out.
Multi-vendor parts depot at Heathrow
We hold same-day parts stock for Dell, HPE, Cisco, NetApp, Pure, Lenovo and Juniper inside an M25 depot — and for kit not in stock, next-day air imports clear Heathrow in time for an evening engineer attendance.
EOSL + post-warranty support
London firms running 7-year refresh cycles on PowerEdge G12/G13, ProLiant Gen8/Gen9, Cisco Nexus 5K/7K and NetApp FAS keep that kit running on Servnet third-party maintenance — typically 50–70% cheaper than vendor TPS at end-of-life.
Weekend windows for trading floors
For City firms with Monday-morning trading-open obligations, all change-window break-fix happens Friday-night through Sunday-afternoon — engineers are physically on-site, parts are pre-staged, and the soak test runs before market open.
What hardware maintenance covers in London
Servers — Dell, HPE, Lenovo, Supermicro
PowerEdge, ProLiant, ThinkSystem and Supermicro break-fix — full motherboard / CPU / memory / drive replacements with engineer attendance, plus the firmware / OS sanity-check before handback.
Storage — Pure, NetApp, HPE Alletra, Dell PowerStore
Controller swaps, disk shelf expansions, drive failures and firmware upgrades on FlashArray, ONTAP, Alletra MP, PowerStore and PowerScale — including the careful path for in-flight rebalances.
Networking — Cisco, Arista, Juniper, Fortinet
Catalyst, Nexus, 7000-series, EX/MX, FortiGate / FortiSwitch break-fix — RMA logistics, configuration backups before swap, post-swap connectivity validation.
Power + cooling support
UPS battery swaps and CRAC unit assistance on APC, Eaton, Riello and Vertiv — for City data hall customers and on-prem MDF / IDF in London office spaces.
Smart-hands inside London data centres
Cabling, patch panel work, cable management, port labelling, physical audits and DCIM updates — billed at hourly rates with no minimum call-out for retainer customers.
Asset register + warranty consolidation
For London estates with mixed warranty status across multiple vendors, we consolidate into one Servnet support contract — single number, single SLA, single invoice across Dell + HPE + Cisco + NetApp.

How London break-fix actually runs
4-hour engineer + parts as the M25 standard
Standard cover dispatches engineer + parts from London-area depot inside 4 working hours of a P1 logged ticket. For City / Canary Wharf P1, typical on-site time is 2 hours; Surrey HQ engineer can be dispatched as secondary if needed.
DC pre-access paperwork held warm
For City data centre customers we hold standing access lists with Telehouse, Equinix, VIRTUS and Global Switch so an engineer can clear security without the customer needing to raise a fresh access request mid-incident.
Parts logistics shaped around the M25
Most common spares (PSUs, disks, fans, GBICs, BBU) are pre-positioned in an inner-M25 depot. Less-common parts (CPU sleds, controllers, blades) ship from UK distribution or air-freight Heathrow with 12–24-hour ETA.
Out-of-hours included on retainer
24×7×4 included on retainer plans — no surcharge for Saturday-night or Sunday-morning P1 attendance. The engineer roster is real, not best-effort.
London hardware maintenance — common questions
Can you attend Telehouse / Equinix / VIRTUS on a 4-hour SLA?
Yes — we hold standing access at Telehouse North/East/West, Equinix LD1–LD8, VIRTUS LONDON1–4, Global Switch and Pulsant central London. Engineer with parts inside 4 hours of P1 ticket logging; for many central London DCs we hit 2 hours.
Do you take over support on out-of-warranty Dell / HPE kit?
Yes — that's the bulk of London third-party maintenance work. We support post-warranty PowerEdge G12+, ProLiant Gen8+, Cisco Catalyst / Nexus, NetApp FAS, Pure FlashArray (older gen) and most enterprise networking. Pricing is typically 40–70% under OEM TPS at end-of-life.
How do you handle vendor warranty interaction during a multi-vendor incident?
For mixed estates we run a single Servnet ticket and handle the OEM ticket creation in parallel. The customer sees one engineer and one ticket; we deal with vendor RMA processes underneath. For under-warranty kit we coordinate; for out-of-warranty we own end-to-end.
Can you do scheduled change-window work on a London trading floor?
Yes — most of our City work happens Friday 18:00 through Sunday 18:00. Engineer on-site for the change window, parts pre-staged, soak test pre-market on Monday. Change-management documentation aligned with bank/firm internal ITIL processes.
Do you stock spares for Pure FlashArray / NetApp ONTAP in London?
Yes — controller heads, drive shelves and SFP/QSFP optics for Pure FlashArray (FA-X, FA-C, FA//XL), NetApp AFF and FAS held in an M25 depot for same-day dispatch. Specific generations on request — we keep stock aligned to the kit our London customer base actually runs.
What's the difference between your London cover and OEM support?
Faster response into central London, lower cost on post-warranty kit, a single engineer face across multi-vendor estates, and no escalation to a US/Asia overnight queue. Trade-off is we're not the manufacturer — so for under-warranty kit OEM is sometimes still the right call.
