GHOST effortlessly transitions NAS workloads to BrickStor SP on Pure FlashArray while preserving your existing compute, network, and backup investments.
Storage migration has always meant a trade-off. Copy data first, cut over last. That’s the standard sequence — the one every NAS vendor builds tooling around, the one every IT team has done at least once, and the one that takes weeks to complete.
For most organizations, the time cost is the obvious problem: maintenance windows, late-night cutovers, weekends consumed by validation runs. The less-discussed problem is what happens during those weeks. The data sits on aging infrastructure that was being retired for a reason — old controllers, deferred patches, security gaps the next platform was meant to close. The migration isn’t just slow. It’s a silent window of exposure, opened deliberately and held open for the duration of the copy.
GHOST inverts the sequence. Cutover first. Copy second. The window of exposure closes on day one.
How GHOST works
GHOST is RackTop’s Instant Migration technology. It changes the order of operations.
Before any data moves, GHOST builds a metadata-complete namespace on BrickStor SP — replicating the source NAS’s file structure, paths, and access controls without copying file content. With the namespace in place, users are redirected to BrickStor SP. That redirect — measured in hours, not weeks — is the cutover.
After cutover, background migration continues invisibly. Files that haven’t yet been copied to BrickStor SP are fetched from the source on demand, transparently to users. People open files normally. The system handles the rest. When the background copy completes, the source can be decommissioned.
The mechanics are straightforward. The implications are not.
What changes when cutover comes first
For IT teams, the cutover stops being a project. The maintenance window disappears. The decision to migrate becomes a decision to start GHOST, not a decision to schedule a six-week phased rollout against the team’s existing workload.
For users, nothing changes — except faster file access on the new platform, beginning the day GHOST cuts over. There’s no outage. There’s no different interface to learn. They open the same paths and see the same files.
For security and compliance teams, the math changes more dramatically. Cyberstorage protections engage at the moment of cutover, not at the end of a multi-week copy. The new infrastructure defends data from day one, not week six. There is no silent window of exposure to manage. There is no risk-acceptance memo to sign that says “we will be defenseless until the end of Q3.”
For the organization, the migration timeline collapses from a calendar quarter to an afternoon.
What this means for Pure Storage Customers
For organizations running Pure Storage infrastructure with NAS workloads GHOST migrates from any source onto BrickStor SP without disrupting compute, networking, or backup investments. BrickStor SP runs on Pure Flash Array. The migration to Cyberstorage doesn’t require new hardware or a procurement cycle. It extends what already works.
See it live at Pure Accelerate 2026
GHOST runs in five-minute live demonstrations at Pure Accelerate 2026, Resorts World, June 16–18 in Las Vegas. Bring a real migration scenario from your environment. Watch a NAS workload cut over to BrickStor SP in real time — in hours, with the source system still serving — and see Cyberstorage protections engage the moment the cutover line is crossed.
Storage migration has been an unsolved problem for years. GHOST closes it. Come watch it work.
RackTop Systems builds Cyberstorage for organizations where data integrity is non-negotiable. BrickStor SP runs on Pure Storage and is Pure Storage-validated. Find RackTop at Pure Accelerate 2026, Resorts World, or learn more at racktopsystems.com.
