Direct-attached storage and JBOD expansion
Sometimes the right answer is more disks on the server you already have. SAS JBOD shelves attach to a server's HBA or RAID controller and add dozens of drives for backup repositories, video storage or a large file server.
We match the shelf to the controller, cable it for redundancy where the shelf supports dual expanders, and configure the RAID or ZFS layout on top.

How we work
Storage projects begin with an honest capacity and performance baseline: how much data, how fast it grows, what IOPS and latency the applications actually need. That baseline decides between an entry SAN, a unified array, a NAS or a hyper-converged design, and it keeps vendors from selling you the biggest box.
We build the network under the storage as carefully as the storage itself: isolated iSCSI paths or dual FC fabrics, multipathing on every host and a failover test before anything goes live. Backups get an immutable copy and a restore test on a schedule.
Migrations are run as projects with a written cutover plan, a rollback path and a validation checklist. Old arrays are decommissioned with certified data destruction and the documentation is handed over.

Frequently asked questions
JBOD or a SAN?
JBOD when one server owns the data. SAN when multiple hosts need shared access or you need controller-level failover.
