A restore card (protection card) is convenient once installed, but the moment you need to push a patch to the lab or swap to a new version of teaching software, the administrator must go machine by machine to pull the card, unlock it, make the changes, then re-seal it — dozens or hundreds of machines can't be finished in a single night. The vDisk Converged Cloud Management Platform moves "system upgrades and updates" to the backend image layer: change it once on the master image, push differential updates to the whole lab with a single click, continue updating or roll back at any time, and the more BT distribution delivers, the faster it goes — no more all-nighters guarding the lab for upgrades.
A restore card solves students' random installs and changes, but it is itself a piece of hardware plugged into the motherboard—every system upgrade or update requires "opening" it first.
IDV5 cloud-desktop core engine—centralized management, local execution; upgrades run in the background while the desktop keeps running on the local machine
There is no longer a "protection card" hardware standing in the middle. The system, patches, and teaching software are maintained uniformly on the back-end master image; once packaged into a new version, they are pushed out with one click. The terminal desktop still runs locally and directly invokes the machine's CPU/GPU, delivering performance on par with a physical machine, while the upgrade process does not disrupt classes in session. The V5 server is rewritten in Go, making distribution both fast and stable.
It does everything a protection card's reboot-to-restore can do, plus what protection cards can't: remote upgrade, rollback and auditing.
One master image deploys to all endpoints, with centralized management via image marketplace/pool—upgrade in just one place.
Only changed differential blocks are deployed instead of retransmitting the whole disk; one-click push to the entire lab makes upgrades fast and bandwidth-light.
Historical versions are retained, so if an upgrade goes wrong you can roll back to the last working version anytime, without rebuilding the whole machine.
Already-downloaded terminals automatically seed and share, so the more you distribute the faster it gets, putting almost no load on the server when upgrading large labs.
If power is lost mid-deployment, transfers resume automatically; use while downloading, without damaging the current image—upgrades never stall.
A clean machine on every reboot — just like a protection card's "tamper-proofing" — so no matter how students mess around, the next class is unaffected.
Pushes, rollbacks, and real-name logins are all logged, so who changed what and when it took effect is fully traceable.
Driver re-engineering brings 4K speed-ups and disk-health alerts, so even old, small drives run stably.
For the same update task, protection cards must be done machine by machine, while vDisk pushes it with one click.
Patch the master image once and seal a new version; push differential updates to the entire lab with one click, no need to pull cards and update machine by machine.
For new-semester version changes of programming/design software, build new images from course templates and deploy them, with rollback anytime if an upgrade goes wrong.
The exam image is delivered separately: upgrade to the exam environment with one click before the exam, then restore to the teaching environment in 30 seconds afterward.
The pure-software image layer needs no hardware cards—new machines join the network, pull the master image and boot directly, so expansion is no longer constrained by cards.
No need to remove all cards at once: switch in batches and keep a parallel window so normal teaching isn't disrupted.
Catalog the protection-card models, motherboard batches, terminal configurations and current teaching-software versions in each lab to establish a baseline.
Pick one lab, install the system and all teaching software, package it into a master image, and verify differential updates and rollback.
Remove the protection cards from one computer lab and switch to vDisk, then run a week of classes to validate compatibility, stability and restoration results.
Migrate off the protection cards in batches by building or lab, keeping the original environment running in parallel for a smooth transition without disrupting teaching.
Thereafter, all upgrades and updates are made by editing the master image in the console and pushing with one click, establishing version and rollback standards.
Not just "switching to another restore solution," but turning upgrades and updates into controllable, rollback-capable, remote standard operations
Edit the master image once and push differential updates to the entire lab with one click, saying goodbye to all-night marathons of pulling and sealing cards machine by machine.
Keep updating while retaining historical versions; if an upgrade goes wrong, roll back to the last working version anytime, no more rebuilding the whole machine.
One image runs on motherboards from many brands and batches, with BIOS/UEFI dual boot, so old machines and small drives keep working.
The desktop runs locally and directly uses the machine's CPU/GPU, so classes go on even offline, with no dependence on servers or the network.
