If you want to maintain sustain write throughput, you want to use an enterprise class SSD. Most consumer SSD only allow momentary burst of speed until its SLC cache is exhausted then the speed would drop by a big margins... Some lower end SSD would even slow to a crawl once the cache is full...

I wanted to refresh my home lab servers from current E5-2680v2 to an EPYC based servers that can run Vsphere 7 or later. My questions is, how much difference in performance do Milan have VS Rome when it is used mainly for ESXi Virtualization ? How about power consumptions of the 2 different...

I have bunch of these same drives in various servers deployment, all of them still working fine even ones with more usage when compared to yours. I think these drives are a great combination of price, performance and durability. Can you clarify what is throwing the error ?? Motherboard bios ...

Most Datacenter grade switches that I've worked with from both Cisco/Juniper are usually fairly loud (if you put it on a desk next to you) I am thinking you might want to check out small business switches from dell, netgear, ubiquity and other similar vendors as those products often time are...

I've had no luck on converting vendor locked firmware with publicly available firmware from the same manufacture for the same part#. This applies to both spinners, ssd, nvme, basically all form factors, and all type of interfaces from sata/sas/nvme. If you are lucky you might be able to get the...

@111alan Just curious what were your plan if you have a backplane ??

Hi all, Recently I've been converting all nvme to 4K logical sector size prior to putting them into use. Unfortunately a few days ago when I tried to convert the sector size on a Dell brand Samsung SM1715 NVME things didn't go as smoothly as my other nvme. Below are the lbaf options when you...

Do you happened to have another cable to try ?? some time cable can be bad too, in fact I have dumped a few cables because one of the breakout cables (facing the disk) just does not work.

@ano did you ever figure out how to dual path nvme on a regular pc ?

The way I did it on my setup is to create the SMB share as shown in my previous post, then connect to it using the domain admin account which have full file system access via "run" and type " \\truenas\smbshare ". After connecting you can build the folder structure using windows file explorer...

that is neat, I didn't know you can actually connect to the truenas box via "computer management"

@kaastrup Here's how I setup my truenas for AD users share folders; 1. Add the truenas server as AD member servers. 2. On your SMB share ACL, assign full permission for everyone 3. On your SMB file system ACL add a new ACL to give your domain administrator full access. once the above steps are...

Interesting I never knew sata based array with expander can have issues with "single bad disks that may block the whole system". Luckily so far I have not experienced this, knock on wood hopefully its not going to happen anytime soon. Anyway thanks for the advice.

So, I recently build a new zfs servers with 12x 12 sata drives in 2 x RAIDZ2 vdevs. The purpose of the server is for a dedicated cifs/smb filers and NFS mounts for both windows/linux machines. Currently the servers have a RMS-200 NVRAM Drive as zil and SYNC=ENABLED, but I am curious whether this...

Most of cisco switches will come with the rails necessary, 9396 have a 4post rack rails so hopefully they are in the box :)
