Hi guys,I have some questions about iSCSI SANs that I'm hoping someone can help me with. I want to deploy a FreeNAS iSCSI SAN (sort of anyway) and I'm wondering if I can use a standard Gigabit switch…Continue

Thanks for posting that,…"

Stefan Pynappels replied to Mike Rigsby's discussion SysAdmin vs. Network Admin"I think this is a good idea, especially if crossover between the roles is also addressed. I work in a small medical software company, and I look after both (Linux) servers and the networks that connect them. I look after these in a variety of…"
Stefan Pynappels posted a discussionServers which meet the following specs:
I am looking for a server with some very specific specifications, and I'm hoping I can get some suggestions here.4 Hotplug Sata HDD slots.Raid 5 capable on 3 HDD with 1 as spare.1 U Rackmount.Lights Out Management.Linux certified (I know, Linux will run on just about anything).Gigabit NIC.1.8GHz+ Processor.4 GB+ RAM.HP Hardware preferred but not a deal-breaker. I know the RAM and Processor specs are pretty basic but I thought I'd add them in the interests of completeness. So, does anybody have…See More

For client support, we use TeamViewer, the only difficulty with it is sometimes when the client runs an older version of TeamViewer, we cannot access it from the iPhone…"
Stefan Pynappels replied to Stefan Pynappels's discussion iSCSI SAN Questions"I've heard that about Openfiler before, but I have 2 ESXi hosts accessing the same VMFS LUN on the Openfiler Server and both have VMs stored on it and running correctly. Not sure about vMotion etc, as I don't have a vSphere…"
Paul Stoklosa replied to Stefan Pynappels's discussion iSCSI SAN Questions"oh.. and if the switch supports it, try turning on jumbo frames for each device from end to end for better performance. And if you want to emulate a production system, use 2 nics in each server, and 2 gigabit switches, connected to 2 ports or nics…"
Paul Stoklosa replied to Stefan Pynappels's discussion iSCSI SAN Questions"A gig switch is a gig switch if that's all you need.. Should be fine.. But beware.. Openfiler is nice.. but I don't believe it supports the 'reservation' required to share a volume between multiple hosts. This is needed for…"
Stefan Pynappels replied to Stefan Pynappels's discussion iSCSI SAN Questions"Ok, I ditched FreeNAS and went for Openfiler. Bit of a pain to set up to run from a USB stick, but worth it. Joined my second ESXi host to it and have VMs on both boxes running from it.
Sweet!"
Stefan Pynappels replied to Stefan Pynappels's discussion iSCSI SAN Questions"Hi Jeff,
Thanks for that reply, it makes sense about having several Initiators accessing the same LUN if the FS allows it, every time I have seen it referred to as a problem has actually been on NTFS drives.
Good news on the switches…"
Jeff Hengesbach replied to Stefan Pynappels's discussion iSCSI SAN Questions"Stefan,
The short answer about the 8 port switches is - sure. iSCSI can go over any network gear. In a lab situation the quality of the switching gear may not be an issue -if the similarity of your lab doesn't have to match…"

Hi guys,I have some questions about iSCSI SANs that I'm hoping someone can help me with. I want to deploy a FreeNAS iSCSI SAN (sort of anyway) and I'm wondering if I can use a standard Gigabit switch for this. I mean to use a couple of gigabit NICs teamed for greater throughput and I have a few spare 8 port gigabit switches which I could dedicate to this lab, but I'm wondering if this would work or if there would be pitfalls to this setup. Is there anything obvious I have missed, or "should" it…See More

- Howdy Stefan! Nice to have you here! So, Linux and Virtualization... do you use KVM? What do you think of RedHat's virtualization offerings?

I've been interested lately in RedHat's virtualization offerings. O have a friend who works for RedHat as a tier 4 support tech and he sings RH's praises and thinks their virtualization product could be a game changer, in a sense. Maybe I'll get around to evaluating it someday.
