Trying to figure out what hardware leads to the best value in an NVMe // SSD array's performance: Please provide Hardware overview of either an SSD or NVMe array. Approximate performance (best recollection) is totally adequate System (if OEM, eg: Dell, HPE, etc) array config (RAIDzX, etc) HBA...

Mikrotik - CRS510-8XS-2XQ-IN - $ 950 8x SFP28 + 2x QSFP28 QNAP QSW-M5216-1T 16p 25GbE - $1200 16x SFP28, 0x QSFP28 Any other switches in this price range I should be looking at..? Anyone think there's a strong reason for the Mikrotik or QNAP offerings..? I originally considered the...

This is both a warning and request for solutions. Dell (and others?) removed admin rights to modify iDRAC via the IPMItool and raw values. Response when tried: "insufficient privilege level" Searching for the phrase returns people searching for solutions to the same issue with: SuperMicro...

I'd assume the Inventec D10056 would be as intolerably loud as any other reg. enterprise switch (I just see some available at potentially reasonable pricing). While STH has written nice things about both Mikrotik and Ubiquiti switches ... it's never in a comparative context as to which is...

Myllenox SFP28 is available as a Connectx-4, Connectx-5 and Connectx-6. Are there any differences to the average user ..? At the core, they all do the same thing ... The only difference I can perhaps think of...is the power used under identical loads. Is there any other reason to prefer one...

System: Dell R7450 with 24x SFF slots supporting NVMe I know SATA can be used in regular SAS slots. I know SFF-8639 for NVMe are the exact same as a SAS slot ... Except having x4 the bandwidth for NVMe I'd just rather not assume anything and ask (the knowledgeable expert) members here able to...

Are there advantages of a homogeneous InfiniBand // If so, what IS infiniband...? Amy other manufactures which provide better performance in their homogenous proprietary network..? Network will consist of a FreeBSD (TrueNAS) server, MacOS peers Thanks. And it goes without saying I'd...

Perhaps the T320 is just too slow for it ... but that seems unlikely, bc my SPINNING drives get faster rates. I'm getting ~650MBs READ ~300MBs WRITE (Granted, the speeds are VERY consistent) ... but I could get that performance with a single drive). RAIDz1 array comprised of 6x EVO 870...

I have a P5800x, but, I think that'd be a waste ... right ..? It's data that's backed up such that if I lost the array it'd be no big deal ... just an inconvenience. In fact, I will not require writes to finish (forgot the setting name). For consumer SATA SSD drives, they're decent (Evo...

For those who'd like 'BREVITY' .... - What performance R or W (100% of either) are the drives able to sustain if the other hardware used doesn't limit them / add a bottleneck..? - Is there a CPU + Motherboard combo you'd recommend that will be quiet, relatively inexpensive which has IPMI or...

I've seen SolarFlare, but they're limited to 10GbE, as is literally EVERYONE except ATTO if I'm not mistaken. The ATTO stuff is so expensive, that it's cheaper to use a PCIe to TB3 enclosure than ATTO if one exists. Better still? Someone shows up with competition to ATTOs. $2,000 for a TB3...

And also, is there a way to use about 10 NVMe (U.2) drives for a TrueNAS device ... that uses low power when it's not in use? I know sleep mode is faux pas... And the EPYC cpus (as AWESOME as they are w 128 PCIe lanes) aren't "low wattage." (hopefully I won't be harangued for wanting to make...

Probably run up to 15x NVMe (U.2) drives. I'll keep it sync'd to a spinning array ... Use some special vDevs ... Probably start off with 4x 8TB NVMe drives + some optanes And a special vDev for small files of optane only. I've thought about making a nested set of RAIDz2 zVols as constituent...

Just completed recovering a failed HP (P410i, total PITA) RAID-5 array. It had an Offset, a startup delay, was Right Sync (if I recall). Truly brutal without access to the SAS SA. The office uses an OLD DL380 with a "RAID-5 for fault tolerance" with either LDAP or AD. I believe the server may...
