FYI: This server has since gone to a new home. After powering off the server about 8 months ago, I took the first steps to selling it. I opened it up and took out 2x NVMe sticks (1TB each, ZFS mirrored, giving a 930G zpool) INTEL fiber NIC (Intel X540-AT2) I’ll be keeping those items. […]

Can I really swap CPU and RAM between my Dell R730 servers? I wrote about that recently. Sure. It might just work. First, let’s look at the service tags and find out. I have four Dell R730 servers in the basement: r730-01 – main development server – contains 2x E5-2650L v3 : add some RAM

I have four Dell R730 servers in the basement: r730-01 – main development server r730-02 – unused r730-03 – main storage server r730-04 – unused So what’s on each one? If you look at each of the links, you’ll find this information on CPU and RAM. The information is collected from /var/run/dmesg.boot, but not presented

This post has been replaced by a newer one. For reference, the previous post on this server is still available. Today I noticed this post is out of date. I like to keep this information around for each host, just in case it’s needed during a rescue mission. This is my primary developer server in

As mentioned in several previous posts, I’m moving a server from one chassis to another. None of the hardware is coming over. Just the jails and data. These drives came from serverpartdeals.com. They are used and re-certified. Recently, I’ve been trying out two new 12TB drives. I’m looking forward to the reduced noise level, as

This morning I pondered how much will noise reduce when I power off that server? From the comfort of my living room, directly above the rack in the basement, I powered it off. At first, I was disappointed. I could still hear that repetitive whine. After considering powering off one of the other hosts, I

Yesterday, the drive cages arrived. Today, the 2x (new-to-me 12TB HDD) arrived. They are already mounted in their drive cages and installed. Let’s look at them. This post is similar to Testing two 12TB drives to a Dell R730 on FreeBSD. If you want to know most about the tests, see that. These drives came

I’m retiring knew and moving the services over to r730-03. I recently added 2 12TB drives to the latter host. In this post, I’ll start the migration process by identifying what data needs to move, from where, and to where. In this post: knew r730-03 FreeBSD 13.2-RELEASE-p2 The data There are the zpools in question:

I’m ready to downsize. I’m going to replace knew with r730-03. The former has 20 5TB drives. I don’t need all that space now. I’ll settle for 12TB instead. The two new drives arrived today: [23:39 r730-03 dvl ~] % grep da2 /var/run/dmesg.boot da2 at mrsas0 bus 1 scbus1 target 2 lun 0 da2: Fixed
