HPE Gen8 servers, iLO NAND flash error – Is iLO needed at all? in c/[email protected]
[–] [email protected] 1 points 10 months ago

You can try and clear it by updating the firmware, failing that you can try one more thing which is a repair of the iLO install, however once it's got to this state its highly likely that the NAND is now fubar. It doesn't stop iLO working as I have a 2nd hand Microserver with the same issue and tried the fixes, but they didn't work, and as such, it's showing the error constantly. The only way to fully fix in the unfixable state is a board swap.

Youtube is a good start, or just browsing posts here on Reddit or elsewhere.

It does depend on your requirements, network, equipment etc for instance I did and could use a consumer based router, for Routing and Wifi. But this means all devices on one network, (Eck!), but also means I couldnt present a "Guest" network on a switch port to say present my work laptop a hard wired network connection but seperate from all my servers etc. So VLAN's was the way for me, as such I went DD-WRT for a start before going over to SMB/Enterprise kit for Networking and then Routing. That then means also the same for Wifi AP's, all meaning that consumer grade kit is out the window, purchasing SMB/Enterprise kit and the requirement for the Cabinet to house the main core equipment.

Start with the basics, how networks work, IP, DNS, DHCP etc, then once you understand that you can then start delving further. Originally (around 15x years ago) I had just a Laptop and Router, then a NAS (piece of poop WD one) which then quickly was replaced by a Windows Home Server, then the tinkering started which DHCP, DNS. Then a proper server with a domain, VPN Server, remote access. Then the more advanced Virtualisation, DHCP Failover, Dual Domain controllers, DFS replication, Veeam backup. Then the networking with VLAN's, ACL's.

Security is again another topic and is a question of do you or don't you need access or restrict access from A to B etc. Such example is with the Wifi, without a Guest or VLAN's Wifi SSID all those guests that come and want a bit of my internet for free would also be able to "see" my network, servers and computers. With that segregated network and ACL's in place no device on the Guest network can see my kit, or talk to each other but just see the internet.

Just wanted to say welcome to the world of labing, and to the work of IT seen as your newish (1 year) to it.

Most of us IT Technicians, Admins etc have been there before and I just wanted to say keep at it, look for what suits you but also pushes your boundaries. Would also suggest not going to deep too soon, as you may learn how to set something up, but its also the support, administration and monitoring that is needed behind this that also takes time to learn. Get comfortable with your system/s before jumping onto the next thing.

Most of the good Sys Admins I have known have had many years experience which I feel is what companies are looking for as they will want a safe pair of hands. Those that are not good, don't have the experience or even the right character to admit and say they F'd up!

One best word of advise is put your lab environment on your CV! This shows willingness to take your own time out to, "purchase" if you do so, learn and do stuff thats relatable to your profession. I'm sure in a few years time, you will have a server rather than a desktop, Level 2 switches all running a proper domain hosting various requirements and be amazed how far you have come.

Hi, yes, I can see the raid config on the controller. The main reason I moved away from the inbuilt one is the lack of 4x disk at full Sata/sas speeds.

The question would be, do you have the disks available and selected to create the raid required?

This weekends project. Microservers, switch and router off the shelf and into a rack (alien.top)
 

This weekends project, from loose networking kit and stacked servers into a rack. I recently upgraded from Dell PowerConnect switches in desktop configuration to TP Link Omada switches. Firstly I upgraded to a SG3428 switch which was much bigger than the Dell 2724 and so wouldn't fit in my neat under the shelf corner spot right under my Microserver stack. I then spotted a great priced SG3428MP which being a POE switch was even bigger than the none POE version. This caused me to lose desk space to this mahusive switch and a mess of cables. I also moved away from a consumer router RT-AC66U over to the Omada ER605 v2 and have 2x EAP650's for wifi.

I decided its time to get a cabinet to house the microservers, POE switch and router. After finding a good priced wall mounting one, with 2x full depth shelves, a brush plate and was deep enough to mount the POE switch.

I decided to mount the switch at the bottom, with the usual 1U gap below the switch, brush plate, then the two shelves with a gap to mount the ER605 on velcro(this is a trick we use at work to mount loose kit) and the top shelf holding the microservers.

Having mounted all the kit and routing the cables through the back and up to the top and out to under the desk on cable trays. It soon became clear that the temperature inside the cabinet would struggle in the UK summer with both servers and switch running. It also became quickly apparent that the size of the switch caused it to sag quite substantially. Amazon next day delivery comes to the rescue, one mains powered 120mm fan with speed controller and a pair of 1U blanking panels on order. Fitting the fan dropped the temps inside the cabinet even just on the lowest setting and thw controller on the outside of the cabinet. With one blanking panel fitted to the back under the switch and the sagging was sorted, the other was just to blank the space under the switch at the front.

Not sure why I haven't done this for ages, nor why I hadn't moved over to SMB/enterprise kit for years and the old Dell switches were just OK for basic use but for more substantial tinkering/setup.
