# Custom B550M NAS Components: - ASRock B550M PRO4 $80 - an X570 like the Asrock X570M Pro4 could include 8x SATA ports, rendering the HBA useless (for now) - Does this mobo have ACS (Access Control Services) to improve IOMMU groups? - Apparently not according this reddit. He says, "B550 is grouping everything in/under it into single IOMMU group." - AMD Ryzen 7 3700X $90 (best value cpu) - A mATX cannot fit both HBA and NIC, so i would need an iGPU, which means PRO for ECC, like AMD Ryzen 7 PRO 5750G - The 'G' versions are 65W, the GE are 35W - each HDD is ~10W, x5 = 50W, + 10W for the mobo, + 10W for RAM, that's 135W total. - $200 with coupon ALIPAY24 on [eBay](https://www.ebay.com/itm/405366854169?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=c3zyb3eqs_6&sssrc=2047675&ssuid=&widget_ver=artemis&media=COPY) - [LSI SATA HBA](https://www.ebay.com/itm/163846248833?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=0zSkXENAR4O&sssrc=2047675&ssuid=&widget_ver=artemis&media=COPY) (pre-flashed to IT mode) $60 - SFF-8087 to 4x SATA forward breakout cables - Actually not required with this mobo since it has 6x SATA, but that is my cap. See [[SATA HBA Notes]] for more information. - [10g Ethernet Adapter](https://www.serversupply.com/NETWORKING/NETWORK%20ADAPTER/2%20PORT/SUPERMICRO/AOC-STGN-I2S_263748.htm?gad_source=1) ($75) or [OWC 10G Ethernet](https://eshop.macsales.com/item/O WC/PCIE10GB/) ($100) or [Intel X540-T2](https://www.ebay.com/itm/166585171595?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=0zSkXENAR4O&sssrc=2047675&ssuid=&widget_ver=artemis&media=COPY) ($60) - [[Network Interface Card (NIC)]] - The NIC will not improve NAS streaming to Apple TV for Plex, since the Apple TV only supports 1Gb LAN. - However, the NIC will improve file transfer speeds from my PC (2.5Gb) to the NAS. - It may also help when serving multiple clients outside of my network by increasing the total bandwidth available to the NAS, but my network upload speed is a likely bottleneck. - Super Flower Leadex VII XG 850W 80+ Gold, Cybenetics Platinum + 3 fans ($155) - could save with smaller PSU since no GPU, like XPG Core Reactor II Modular PSU ($80) - Node 804 $130 - RAM [QVL](https://www.asrock.com/mb/AMD/B550M%20Pro4/index.asp#MemoryMS) for this mobo (Matisse): - KSM26ED8/32ME - KSM26ED8/16ME - Random person said: KSM32ES8/16ME x2 (32GB ECC) $180 - This one (KSM32ES8/16ME) is single rank while the 32GB module (KSM32ED8/32ME) is dual rank. - They also have 16GB KSM32ED8/16MR and KSM32ED8/16HD modules with dual rank configuration. But it's hard to find these ECC udimms. They sent me the wrong RAM. They sent KSM32ED8/16HD See [[About RAM]] ![[Pasted image 20241127121437.png]] ![[Pasted image 20241127121636.png]] [[ZFS (Zettabyte File System)]] ## Order Details - RAM (120) + cooler (90) = $225 total, latest in order expected Nov 29 [Amazon] - They sent the wrong RAM - 1x32GB creates an upgrade path - What is the all-time best 1x32GB DDR4 unregistered/unbuffered 2Rx8 RAM with ECC from Kingston? - Hynix C vs Micron R Rambus? - 2Rx4 is better for servers while 2Rx8 may be more compatible with consumer hardware. 2Rx4 (dual-rank x4) configurations are typically associated with registered (buffered) memory modules. - That leaves KSM32ED8/32HC - 115 at https://www.newegg.com/kingston-32gb/p/0RN-001J-013R4 - 74 at provantage - Kingston Technology 32GB 3200MHZ DDR4 CL22 DIMM 2RX8 Hynix C **OPEN BOX** - 160 total, +$30 for +32GB, worth - TrueNAS uses RAM for caching. You should max our your RAM before looking into things like a cache drive. For SCALE, 64GB would be my minimum. - Micron E-die is the only ECC ram on QVL - Apparently KSM32ED8/32ME works... - CPU (93) + PSU & FANS (155) + MOBO (80) + Case (130) = $512, with all but CPU expected Nov 27, w CPU Dec 6-17 [Newegg] - 10GB Nic ($75) expected Nov 23 - 26 [eBay] - had to get Intel X550-T2 ($161) instead for Link Speed Negotiation - had to add PWM fans + controller **Total:** $812 + 30 + 86 + 62 = 990 178 of unexpected expenditures... Still, thinking of adding another $227 drive to increase utilization... since adding a drive later is a hassle. No [[IPMI (Intelligent Platform Management Interface)]].
