The iStarUSA D Storm D-407P-DE4 is a compact yet powerful 4U rackmount chassis engineered for demanding storage, server, and clustering environments. With four hot-swappable 3.5" bays delivered in a trayless backplane, this chassis simplifies maintenance, minimizes downtime, and enables flexible RAID configurations. Designed to handle enterprise workloads, it supports up to seven add-on PCIe cards and scales to as many as nine drives when configured for RAID, making it an ideal foundation for high-availability NAS, data-center clusters, or performance-driven compute nodes. Built to endure in rack enclosures, the D-407P-DE4 blends sturdy construction with efficient cooling and streamlined serviceability for steady, long-term operation.

  • Trayless 4x3.5" hot-swappable bays: Enjoy effortless drive replacement without the need to deal with cumbersome drive trays, enabling faster maintenance and reduced downtime in busy data centers.
  • 4U rackmount form factor: A compact chassis footprint that fits standard 19-inch racks, delivering strong expandability within a familiar server room layout.
  • High expandability with PCIe: Supports up to seven add-on PCIe cards, enabling flexible I/O expansion for controllers, NICs, accelerators, and more to suit diverse workloads.
  • RAID-ready capacity up to 9 drives: Total storage capacity scales to nine drives when paired with the appropriate backplane and controller, making it suitable for RAID arrays that balance performance and redundancy.
  • Industrial-grade reliability for servers and clusters: Built to support continuous operation in demanding environments, ensuring data integrity, uptime, and scalable performance for your critical workloads.

Technical Details of iStarUSA 4U D Storm D-407P-DE4

  • Chassis model: D Storm D-407P-DE4
  • Form factor: 4U rackmount chassis
  • Drive bays: 4x 3.5" hot-swappable (trayless) backplane
  • Maximum drive support: Up to 9 drives for RAID configurations
  • PCIe expansion: Up to seven add-on PCIe cards
  • Enclosure type: Standard server-grade chassis designed for reliability and airflow in data centers

How to install iStarUSA D Storm D-407P-DE4

  • Prepare your rack: Confirm rack compatibility, weight capacity, and clearances. Use the included rack ears and mounting hardware to secure the 4U chassis in a stable position within a standard 19-inch rack.
  • Install the backplane and drives: With the chassis secured, insert four 3.5" drives into the hot-swappable bays on the backplane. Since the design is trayless, you rely on the backplane’s hot-swap mechanism for drive installation and removal. Ensure all connections are properly seated and that the drives are recognized by the backplane.
  • Populate PCIe expansion slots: If your build requires extra I/O, install up to seven PCIe add-on cards in the available expansion slots. Use anti-static precautions and secure each card with the appropriate screws to maintain reliability under vibration and movement.
  • Connect power and data: Attach the chassis power supply connections and connect data cables between the backplane and the motherboard or RAID controllers as required by your configuration. Verify SAS/SATA cabling, power rails, and cooling pathways to promote stable operation.
  • Power up and configure: Boot the system and enter the BIOS/RAID controller configuration. Initialize and configure your RAID array as needed, verify drive detection, monitor thermal sensors, and ensure fans are operating properly to sustain airflow across all components.

Overpriced but effective.
Color: Cream
I happened to get lucky and get a warehouse deal at an additional 30% discount. Even at $25, it feels a little overpriced. But it was easy to assemble and serves its purpose. If you line the Velcro up exactly, the panels sag, if you stretch past even, but where it still grips, they look pretty ok. It is very light and does fold very compact for easy storage.

Great price for a great product
Color: Coal Black
Excellent quality and great price to boot. Easy to assemble and folds up easily to be stored. We are using it as a privacy screen when we have company that needs to sleep on the couch and also to block off a hallway leading to a guest suite. It looks great and is as described in the ad

No.
Color: Coal Black, Color: Coal Black
This was horribly made and a nightmare to put together. You have to basically bend the bars to get the coverings attached. The sizes don't match. The stickers that label the parts are impossible to remove and if you do get them off theres a lot of residue left behind. On top of that once it was put together I noticed theres a big dirty foot print on it which is definitely not mine.

You have to add weight to it
Color: Coal Black
It does its job and it was easy to put together but it's a little on the flimsy side and it will easily be knocked down. So you're going to have to figure out a way to make the legs heavier? I used cinder blocks, single cinder blocks and it works just fine. Just know that it will knock over super easy
