SAN Data Recovery Swindon

When shared storage stumbles, every server leaning on it falls together. We reconstruct SAN estates — LUNs offline, pools corrupted, VMFS datastores refusing to mount — for businesses and IT providers across Swindon and Wiltshire, from single shelves to multi-shelf arrays Enterprise server data recovery is core bench work here.

Free diagnostic on every san job. One fixed quote in writing before any work begins.

No fix, no fee all jobs except electronic and mechanical failures, chip level work, DVR and Forensic jobs. Full pricing is on the data recovery cost page.

// top 20 faults we recover from

The twenty ways they fail

Every san job starts by matching the symptoms to the fault — these twenty cover almost everything that reaches the bench.

Clustered drive failures

Enterprise shelves shed members in groups; each casualty gets individual repair and imaging before the group maths.

LUN offline

The block device your servers stood on vanishes — rebuilt upward from pool metadata and RAID groups.

Pool metadata damage

The map from blocks to LUNs gives way — reconstructed from the raw on-disk structures it described.

Bricked controller update

Mid-update firmware death takes out the management plane; the data behind it never moved.

Dual-controller death

Redundant pairs die together more often than brochures admit — recovery then goes drive-direct.

VMFS datastore corruption

The VMware layer collapses above healthy LUNs — datastores and their VMDKs get parsed out and repaired.

LUN deleted / re-provisioned

Provisioning slips take seconds; what survives depends on the writes since, so freeze the platform.

Snapshot chain breaks

Break one link and all dependent volumes fall — the chain is sewn back together at capture level.

Thin-provision overrun

A pool that promised more than it owned corrupts every thin volume drawing on it.

Cache write-hole

Dead cache batteries plus a power event leave parity disagreeing with data right across the group — reconciled from images.

Aggregate / pool map loss

Aggregates on NetApp and pools on Dell EMC drop their LUN maps — reconstruction starts at the RAID groups and climbs.

520/528-byte sector stock

Enterprise sector formats defeat desktop tools; the lab fabric images them natively.

MSA 2040 / 2050 shelf faults

HPE's small-business SAN staple arrives with vDisk metadata damage — well-practised reconstruction here.

Storwize pool corruption

IBM V3700 and V5000 pools drop extents after power events — remapped directly from the drives.

Vanished iSCSI target

The box took the target definition with it, yet the volume behind that target generally survives for extraction.

Deduplication metadata loss

When the dedupe index corrupts, every pointer breaks at once — rebuilt so the shared blocks resolve again.

Split-brain after failover

Both controllers wrote independently during a botched failover — the divergent halves are reconciled at image level.

End-of-support arrays

Kit long past vendor support fails with no official path left — the lab route stays open regardless of contract status.

Mixed firmware after a drive swap

Replacement drives on different firmware misbehave inside old groups — stabilised and imaged before reconstruction.

Host mapping lost

Fabric or zoning changes hide healthy LUNs from every server — the mapping is rebuilt and the volumes handed back.

Unpicking the stack, layer by layer

A SAN is a tower of abstractions: physical drives in RAID groups, groups pooled, pools portioned out as LUNs, and file systems or hypervisor datastores occupying the top floor. Recovery climbs down and back up: image the drives, stand the RAID groups back up, reconstruct pool metadata, lift out the LUNs, then open the VMs and databases inside. Dell EMC, HPE MSA/EVA, NetApp, IBM and Fujitsu hardware are all familiar, and NDAs and change-control paperwork slot into the process without friction.

Critical servers first, bulk data second

No business actually wants raw blocks — it wants the three machines that run everything back online. So datastores are mounted from the rebuilt LUNs, VMDK and VHDX files come out for repair, and named SQL or Exchange workloads move to the front so operations restart while the remaining terabytes are still copying in the background.

// the equipment we use

A professional lab, not software guesswork

SAN work needs enterprise plumbing as much as recovery skill, and the lab keeps both on hand:

FC / SAS / iSCSI lab fabric

Enterprise shelves and drives attach over the lab's own FC, SAS and iSCSI plumbing, exotic 520/524/528 sector sizes included.

Parallel enterprise imaging

RAID groups are captured side by side once any casualty member has finished its visit to the PC-3000 rigs.

Pool & LUN reconstruction tools

Vendor metadata parsed and rebuilt in sequence: RAID groups, then pools, then LUNs, then the file systems on top.

VMFS / VMDK / VHDX parsers

Rebuilt LUNs host their datastores again; each virtual disk is then lifted out and mended in turn.

Database-aware extraction

Named SQL Server and Exchange workloads verified and moved to the front, so critical services restart first.

Write-blocked workflow throughout

Originals — drives and shelves alike — remain read-only from booking-in until the day they go home.

Platforms handled regularly

An unfamiliar badge is rarely unfamiliar hardware — the enterprise market rebadges the same building blocks endlessly. Pools that mislay their LUN maps get rebuilt from the RAID groups up; a double controller failure just sends the work straight to the drives; and 520/528-byte enterprise sectoring images natively on the lab fabric instead of fighting desktop adapters.

// before you post it

Sending it in — remove the drive if you can

Tag every drive with its shelf and slot positions before anything comes off the rack — enterprise layouts forgive nothing where order is concerned. The tagged drives are all that ships (photograph the configuration first); shelves and controllers remain on site.

// getting your device to us

Post or courier your device — it's simple

Most customers post or courier their media to us.

Sending a drive from a computer, laptop, MacBook, iMac, CCTV / DVR or server? Please remove the internal hard drive or SSD and send us just the drive — we don't provide an internal drive-removal service. We don't recover storage soldered to a motherboard (e.g. Apple Silicon Macs and some thin laptops) — only drives that can be removed and sent to us.

  • Wrap the device in bubble wrap or a padded envelope — no need to include cables or power supplies.
  • Print and enclose the booking-in & shipping form (PDF) with your name, phone number and a brief description of what happened.
  • Send by Royal Mail Special Delivery or any tracked courier for full insurance in transit.
  • Prefer to hand it over in person? You can drop it in at reception at the address shown, Mon–Fri 9:00am–5:30pm.

// san recovery questions

Common questions

Freeze the environment: halt writes, refuse any initialisation prompt, change nothing further. Then phone through the make, model and any layout notes that exist, and we'll say whether drives, shelves or the complete chassis should make the journey.
Yes — VMFS reconstruction over rebuilt LUNs is one of the most regular enterprise jobs here. Name the critical VMs and they're extracted first, so services restart long before the final byte copies.
As standard. Confidentiality agreements, change control, documented handling, then a clean hand-over for your own team to restore from — we're frequently the invisible lab behind an MSP's own offering.
Assessment begins the day the media arrives. Ring 0800 689 0668, say 'business-down', and the logistics get settled during that first call, courier collection included where distance allows.
