Bitmain Antminer L9 Hyd 2U (27GH)

27 GH/s Scrypt at 5,670W continuous draw and 0.21 J/MH (210 J/GH) efficiency. Bitmain's ±3 percent tolerance produces real world output between 26.2 and 27.8 GH/s. 59 percent more hashrate than the air cooled L9 at 17 GH/s through hydro cooling's ability to sustain higher chip power density.

2U rack mount chassis at 445 x 88 x 670 mm per MillionMiner's specification. The 88 mm chassis height corresponds to 2U in standard 19 inch rack measurement. Fits standard server racks without custom mounting hardware. 21 units per 42U rack produces 567 GH/s total.

50 dB from the liquid to chip cooling design, roughly 75 percent less perceived loudness than the 75 dB air cooled L9. Staff can work around deployed hardware without hearing protection. Air cooled L9 deployment typically requires hearing protection for extended exposure.

External facility hydro infrastructure required. Unlike the L11 HU6 with integrated all in one cooling, the L9 Hyd 2U connects to external coolant distribution unit (CDU), dry cooler or chiller, heat exchanger, pumps, and plumbing. Deployment requires existing hydro capacity or facility CapEx to build it. For facilities without existing hydro infrastructure, the L11 HU6 (integrated cooling) or air cooled L11 Pro are alternatives.

380 to 415V three phase industrial input with approximately 12A maximum current per phase and 50 to 60Hz frequency range. Not available in residential or most light commercial settings. Purpose built for professional mining facilities with three phase power distribution.

All Scrypt algorithm cryptocurrencies through merged mining. Primary coins: Litecoin (LTC), Dogecoin (DOGE), Bellscoin (BELLS). Additional Scrypt coins: Luckycoin (LKY), Junkcoin (JKC), Pepecoin (PEP). Combined revenue typically runs 20 to 40 percent above solo LTC at the same hashrate.

21 units per 42U standard rack at 567 GH/s total Scrypt hashrate and approximately 119 kW continuous power per rack. Compared to the newer L11 Hyd 2U at 35 GH/s per unit (735 GH/s per rack, 23 percent higher density), the L9 Hyd 2U delivers the lower capital entry tier into rack mount hydro Scrypt deployment.

Yes. MillionMiner hosting services accept L9 Hyd 2U units at managed facilities with three phase power and existing hydro cooling infrastructure. The 380 to 415V input and 5,670W draw align with industrial hosting standards. Contact MillionMiner for hosting rate tiers and availability.

L9 Hyd 2U při 27 GH/s, 5670W a 0,21 J/MH. L11 Hyd 2U při 35 GH/s, 5676W a 0,162 J/MH. L11 Hyd 2U nabízí o 30 procent více hashrate při téměř stejné spotřebě (o 23 procent lepší efektivita na megahash) ve stejném formátu 2U rámu. Stejné vodní chladicí připojení umožňuje smíšené nasazení racků během přechodů flotily z L9 na L11. L9 Hyd 2U vyměňuje hashrate a efektivitu za nižší pořizovací náklady na jednotku.

Air cooled L9 at 17 GH/s, 3,570W, and 0.21 J/MH. L9 Hyd 2U at 27 GH/s, 5,670W, and 0.21 J/MH. Same BM1485 chip architecture and same efficiency per megahash. Hydro cooling enables 59 percent more hashrate per unit through sustained higher chip power density without thermal throttling. Power draw increases proportionally to hashrate gain. The hydro variant trades air cooled deployment simplicity for rack mount density and 50 dB acoustic advantage.

L9 Hyd 2U při 27 GH/s, 5 670 W, 0,21 J/MH v 2U skříni vyžadující externí hydroelektrárnu. L11 HU6 při 33 GH/s, 5 676 W, 0,172 J/MH s integrovaným all-in-one chlazením eliminujícím infrastrukturu externí zařízení. L11 HU6 poskytuje o 22 procent vyšší hash rate při o 18 procent lepší účinnosti a odstraňuje bariéru kapitálových výdajů na hydroelektrárnu. L9 Hyd 2U nabízí výhodu hustoty 2U skříně (21 jednotek na 42U rack vs 7 jednotek) pro zařízení s již existující kapacitou hydro.

445 x 88 x 670 mm chassis at 20 kg per MillionMiner's specification. Alternative distributor documentation (Mining Now, CryptoMinerBros) lists 509 x 481 x 87 mm at 19.1 kg. The slight dimensional and weight discrepancy may reflect shipping packaging versus bare chassis. Verify with MillionMiner for logistics planning.

No. The 380 to 415V three phase input is not available in residential settings. 5,670W continuous draw requires industrial electrical service with three phase distribution. The 2U rack mount chassis requires 19 inch rack infrastructure. External hydro cooling loop requires facility infrastructure. For quiet home Scrypt mining, Fluminer L3 at 9.5 GH/s and 45 dB or Fluminer L1 Pro at 6 GH/s and 45 dB are appropriate options.

5 až 45 stupňů Celsia při vlhkosti 5 až 95 procent podle specifikace MillionMiner. Alternativní dokumentace distributora (CryptoMinerBros) uvádí 20 až 50 stupňů Celsia, což odráží potřebu hydrochlazení udržovat chladicí kapalinu nad bodem rosného bodu kondenzace. Pro nasazení v chladném klimatu s teplotami zařízení pod 20 stupňů Celsia ověřte specifikaci chladicí kapaliny s dokumentací Bitmain.

Four step setup. Verify 380 to 415V three phase service capable of 5,670W continuous. Connect PSU to miner. Connect water cooling inlet and outlet to facility CDU or cooling loop. Connect Ethernet. Find miner IP, open Bitmain web interface, configure Scrypt merged mining pool URL and LTC/DOGE/BELLS wallet addresses, change default credentials. Verify hashrate reaches 26+ GH/s within 10 minutes.

Major Scrypt merged mining pools accept L9 Hyd 2U hashrate including F2Pool, Poolin, ViaBTC, Prohashing, Litecoinpool. Pool fees typically 0.5 to 2 percent. Verify Bellscoin support before deployment since not all Scrypt pools have added BELLS.

Third party Scrypt firmware support is less mature than SHA-256. Most L9 Hyd 2U operators run stock Bitmain firmware. Some BraiinsOS style tuning has targeted earlier Scrypt hardware but L9 Hyd 2U specific deployment is limited. Plan for stock Bitmain firmware operation.

Pro factors: lower acquisition cost than current generation L11 hydro, 2U rack format matches L11 Hyd 2U for fleet transition flexibility, 50 dB acoustic advantage over air cooled, mature Bitmain firmware ecosystem, 21 units per 42U rack density. Con factors: L11 family delivers 18 to 23 percent better efficiency per megahash, requires external facility hydro infrastructure (L11 HU6 eliminates this), 380 to 415V three phase excludes non industrial facilities. For facilities with existing rack mount hydro infrastructure prioritizing capital efficiency over latest generation performance, the L9 Hyd 2U delivers competitive fleet expansion economics.

For Scrypt family upgrades: L11 Hyd 2U (35 GH/s) drops into the same rack slots with better efficiency, L11 HU6 (33 GH/s) offers integrated all in one cooling eliminating facility hydro infrastructure, air cooled L11 Pro (21 GH/s) and L11 base (20 GH/s) for facility zones without hydro. For algorithm diversification: Antminer S21 XP (270 TH/s), S23 (318 TH/s), or S23E Hyd 2U (865 TH/s) cover SHA-256 Bitcoin with similar three phase hydro deployment. Antminer KS7 (45 TH/s) covers Kaspa KHeavyHash. For quiet Scrypt on separate infrastructure: Fluminer L3 (9.5 GH/s, 45 dB) or Fluminer L1 Pro (6 GH/s, 45 dB). Bitdeer SEALMINER DL1 Air (25 GH/s) provides air cooled vendor diversification. MillionMiner's ASIC hosting service covers turnkey L9 Hyd 2U deployment without facility CapEx.
