Enterprise IT Hardware in Oklahoma

Yes — HPE ProLiant DL360 and DL380 Gen9 and Gen10, Dell PowerEdge R630, R730, R740 and R750, Lenovo ThinkSystem and Supermicro, as complete systems and as parts for specific models.

Yes. Tell us the model and generation — DL380 Gen9, R730, ThinkSystem SR650 — and we quote drives, caddies, memory, processors, controllers and power supplies against that platform.

High-capacity CMR nearline drives in a double-parity array. Seismic datasets are large and sequential and are read far more than written, which favours capacity and sustained throughput over spindle speed.

Yes — LTO-6, LTO-7, LTO-8 and LTO-9 drives and media, plus autoloaders and libraries from HPE StoreEver, IBM, Quantum and Overland. Tape remains the practical answer for large seismic and imaging archives.

LTO drives generally read two generations back and write one generation back, with limits that changed from LTO-8 onward. Tell us the drive and the media you hold and we will confirm before you buy either.

Yes. Send the quantities and the platforms and we quote line by line with condition, drive hours and availability stated on each.

600GB 15K SAS, 900GB SAS, 1.2TB, 1.8TB and 2.4TB 10K SAS, and 4TB, 8TB, 10TB, 12TB, 16TB and 20TB nearline drives, in 12Gb/s SAS and 6Gb/s SATA.

Seagate Exos, Western Digital Ultrastar and Toshiba, plus vendor-coded HPE, HP, Dell, IBM, Lenovo and NetApp stock.

Spindle speed trades capacity for latency. 15K SAS suits transactional workloads, 10K is the general-purpose middle, and 7,200 RPM nearline gives the most capacity per bay for archives.

A 7,200 RPM high-capacity drive with a SAS interface rather than SATA. You get capacity economics with SAS queueing and dual-port capability, which is why arrays favour it.

1.92TB, 3.84TB and 7.68TB in 12Gb/s SAS, 6Gb/s SATA and NVMe U.2, plus M.2 — Samsung, Micron, Intel, Seagate Nytro, Kioxia and vendor-coded HPE and Dell.

Endurance. Read intensive drives are rated around 1 DWPD and suit mostly-read workloads; mixed use is typically 3 DWPD for databases and virtualisation. A read intensive drive in a write-heavy role wears out early.

Drive writes per day and terabytes written — how much can be written over the warranted life. Match the rating to the workload rather than assuming any enterprise SSD suits any role.

Both are 2.5 inch NVMe form factors. U.3 backplanes accept U.2 drives, but U.2 backplanes do not accept U.3 — the compatibility runs one way only.

512n, 512e and 4Kn describe how a drive presents its sectors. Mixing formats in one array is refused or unpredictable, and it frequently surfaces during a rebuild rather than at installation.

Yes, always. SMR write performance collapses part-way through sustained writes, and a rebuild onto an SMR drive can fail outright. We state CMR or SMR on every listing.

Yes. The drive reports it exactly and we check before listing. At volume we can state the range across the batch.

Yes — Dell PERC H730, H730P, H740 and H965i, HPE Smart Array P440ar and P408i, plus LSI and Broadcom HBAs and QLogic and Emulex fibre channel HBAs.

Yes. This is the part that fails silently — the controller drops the array into write-through and performance falls off with no obvious error. A replacement pack is cheap relative to the symptom.

A host bus adapter that passes drives through to the operating system without RAID abstraction — an LSI 9207-8i or 9300-8i, for instance. Software-defined storage and ZFS need it.

Yes — Dell drive caddies and HPE Smart Carrier trays, plus drive blanks. We stock them alongside the drives, because a drive without the right caddy will not go in the bay.

No. Smart Carrier trays changed across generations and do not cross. Tell us the server model and generation and we supply the right one.

Yes. Rails are chassis and rack specific, and a server without the right rails does not mount safely. Tell us the model and rack depth.

Yes. Risers determine which PCIe slots are usable and at what lane width, which is why an adapter that fits physically may still run slower than expected.

Yes. Heatsinks are frequently processor and chassis specific, and a CPU upgrade sometimes needs a different heatsink.

16GB, 32GB, 64GB, 128GB and 256GB DDR4 RDIMM and LRDIMM registered ECC in DDR4-2400 PC4-19200, DDR4-2666 PC4-21300 and DDR4-3200 PC4-25600, plus DDR5-4800 and DDR5-5600 and DDR3-1600 PC3-12800.

Samsung, Micron, SK Hynix, Kingston and Crucial, plus HPE and Dell coded modules where the platform expects them.

RDIMM buffers the address and command lines, LRDIMM buffers the data lines too and allows much higher total capacity, and UDIMM is unbuffered. They do not mix in the same system.

Population rules. Filling more ranks or more slots per channel forces the bank to downclock, and the processor also has a maximum supported speed. The modules are not faulty.

You can, but everything runs at the slowest common speed and unbalanced population costs you channel performance. Populate in matched sets per the platform’s memory guide.

Yes, along with Xeon Scalable Bronze, Silver, Gold and Platinum from 8 to 28 cores, and AMD EPYC and Opteron.

No. Both sockets need matching models. A mismatched pair either refuses to boot or runs on one socket.

Frequently yes, and the BIOS has to be updated before the new processor goes in. Tell us the server and current firmware level and we will flag it.

Yes, by wattage — 495W, 750W, 800W, 1100W and above — for HPE, Dell and Supermicro platforms.

Generally no. Redundant supplies should match on wattage and usually on part number; a mismatched pair commonly logs a fault and may not provide redundancy at all.

Yes. Surges and repeated outages shorten the life of drives, controllers, printers and network hardware, which matters more in Oklahoma than most states.

On schedule rather than on failure. Heat is what kills UPS batteries, and a unit several years in may hold a fraction of its rated runtime while reporting itself healthy.

Because a self-test draws far less than a real outage. Test under real load periodically rather than relying on the self-test.

Yes, including UPS battery replacements.

Yes, including SFP-10G-SR, QSFP+ and QSFP28.

Often not. Many switches only accept transceivers coded for that vendor and simply refuse others. Tell us the switch make and model and we supply the correct coding.

Yes — Intel X520 and X710, Mellanox ConnectX and Broadcom adapters in PCIe, OCP and mezzanine form factors, plus Cisco Catalyst and comparable PoE+ and 10GbE switches by port count.

Yes, measurably. Equipment rooms without dedicated cooling run far hotter than the building, and sustained heat shortens drive life. Monitor intake temperature rather than the wall thermostat.

Frequently thermal throttling. Processors reduce speed to stay within limits and report no fault — the machine just runs slower. Check intake temperature, fans and air baffles.

For anything where downtime is unacceptable, yes. When severe weather suspends carrier service, a part on your own shelf is the only part you have.

Drives in production arrays, a printhead per printer model in continuous use, a spare scanner per shift, and a matching power supply for any non-redundant server.

Tell us the platforms and printer models you run and your refresh timing. It commits you to nothing and it changes what we can do when something fails.

We ship when carriers are operating. During a suspension nobody can move freight, and we will tell you that plainly rather than accepting an order we cannot fulfil.

Yes. Zebra and SATO industrial printers suited to part marking, traceability and maintenance record labelling, with printheads and spares.

Labels have to remain readable through a component’s service life, which usually means thermal transfer with a resin ribbon rather than direct thermal. Tell us the surface and environment.

Sun, heat and weather destroy direct thermal quickly. Thermal transfer with a resin ribbon on a weather-rated facestock is the usual answer — tell us the exposure and expected life.

At least one per printer model in continuous use. Printheads are consumables with a rated life measured in linear distance printed, not parts that fail unexpectedly.

Read the part number off the existing printhead or the printer label. Printheads differ by resolution for the same printer model and do not cross between models.

A dead heating element in the printhead. It appears in the same position on every label, does not heal, and more elements will follow.

Calibration. The printer detects label boundaries with a sensor, and changing media size, liner or gap requires recalibrating.

No. Data Matrix codes used in part marking are 2D and require an imager. A 1D laser cannot read them at all.

Yes. Zebra and SATO printers for patient identification, wristband and specimen labelling, plus genuine replacement printheads.

Yes, to every address in the state, including the Panhandle and the rural counties.

Oklahoma is a moderate distance from West Palm Beach. Eastern Oklahoma and Tulsa are marginally closer than the Panhandle and the far west.

No. We ship from West Palm Beach, Florida, and we would rather state that plainly than imply a distribution network we do not have.

Yes, including Catoosa, Claremore, Owasso and the surrounding logistics addresses.

Yes — Guymon and the surrounding counties, which carriers treat as extended delivery areas. Transit is longer and we will say so up front.

Yes. We accept purchase orders from organisations, offer Net-30 on approval, and complete vendor registration forms and W-9s as required.

Yes, with the purchase order, formal quotation and vendor registration process their procurement requires.

Yes. Send the list with part numbers, quantities and the target system for each line, and you get it back priced per line with exact part number, condition and availability stated.

Sales tax is applied where we are required to collect it. If your organisation is tax exempt, send your exemption certificate before ordering.

Our target is one business hour, Monday to Friday, 9:00 AM to 6:00 PM Eastern — 8:00 AM to 5:00 PM Central.

We state the condition on every line. Ask for the specific condition, the testing performed and the drive hours where applicable.

30 days. Raise a problem promptly — the sooner it is raised, the more options there are.

Yes, and before it goes into production. Failures cluster early in life and transit damage frequently does not show until equipment runs under load.

Yes. Several of our guides recommend against a purchase where the workload does not justify it, and we apply the same approach to quotes.

Contact us with a list of what is coming out and we will tell you what it is worth and what is worth keeping as spares.

Call (954) 601-5103 or email sarah.jane@techsellerusa.com. Business hours are Monday to Friday, 9:00 AM to 6:00 PM Eastern — 8:00 AM to 5:00 PM Central.
