Samsung PM1743 MZ-WLO7T60

7.68TB PCIe 5.0 x4 NVMe, U.3 2.5" form factor, 1DWPD TLC NAND

PCIe 5.0 doubles the bandwidth of PCIe 4.0
NVMe sequential reads push past 13,000 MB/s.

For AI pipelines and high-throughput storage, that’s the difference between a storage layer that keeps up and one that bottlenecks everything.

Most standard server racks were designed before GPU servers existed.

Standard racks are 600mm wide, ~1000mm deep.

GPU servers are deeper, heavier, and run hotter.

Teams that force them into standard racks end up with doors that won’t close and thermals that go sideways

Basic = power only.
Metered = power + monitoring.
Switched = remote per-outlet on/off control.

APC AP7968 — refurbished switched Zero-U rack PDU, 24 outlets, 3-phase 208V, 12.5kW, 35A, vertical mount.

Most people know what a PDU does. Fewer know the difference between basic, metered, and switched.

In a colo or remote DC, switched is the difference between a remote reboot and a 2am site visit.

AMD EPYC 9D25 QS — 128 cores, 256 threads, 3.2GHz turbo, 400W TDP, SP5 socket. Brand new. Production-spec silicon, non-retail price.

[UNIXSurplus Inc @unixsurplus]

Most people see “QS” on a processor listing and assume it’s a downgrade. It’s not.

QS = Qualification Sample chips AMD produces during final validation before full production.

Same spec, same die, same architecture as the retail chip. Different channel, different price

The Hoffman E4DRS19FM45U — refurbished 45U 4-post open-frame server rack, 2,500 lb capacity, 12-gauge steel, adjustable depth 17.7" to 41.3", EIA square-hole standard.

Most people picture an enclosed cabinet when they think server rack.

But in a dedicated server room with controlled access, open-frame is often the smarter choice, better airflow, easier cabling, faster to reconfigure, and lower cost.

The Micron 7450 Pro E1.S 15mm — 7.68TB brand-new PCIe 4.0 x4 NVMe, read-intensive TLC, hardware SED encryption. Built for the servers modern data centers are being designed around.

[UNIXSurplus Inc @unixsurplus]

Most people know M.2 and U.2 drives.
Fewer know E1.S and it’s becoming one of the most important form factors in data center storage. EDSFF was designed specifically for high-density NVMe: better thermals, better airflow, more drives per rack unit.

#SONiC #OpenNetworking #100GbE #VendorFreedom

[UNIXSurplus Inc @unixsurplus]

Most teams don’t realize they have a choice in what OS runs their network switches. Traditional enterprise switches bundle proprietary software with hardware — changing vendors means starting over. SONiC breaks that dependency entirely.

The Supermicro AOC-STG-I4T gives you 4x 10GbE RJ45 ports, Intel 82580 controller, PCIe x8 — broad VMware, Windows Server & Linux support.

Still on 1GbE?
This is your upgrade.

[UNIXSurplus Inc @unixsurplus]

10GbE is one of the most impactful server upgrades you can make. RJ45 is the reason most people actually follow through. SFP+ needs transceivers and fiber. RJ45 uses Cat6 you already have — plug in and you’re at 10Gbps. No extra hardware, no complexity.
