System i and VCB

Posted by dave@NLC Dec 21, 2008

Anyone who knows me knows I get a little excited about new technology. So when I heard about all the great enhancements that v6r1 was bringing to the table, I jumped on it. I was excited about the obvious things, vMotion was supported. I got everything up and running, it works great, but how could I use the system i to back it all up. Well a couple of months have gone by, and I finally got around to reading the redbook! VCB works! And it's easy!

Before I get into VCB let me quickly tell you what I have learned. You should have your vCenter Server be an integrated Windows Server, this way you can shut down the VM's from the System i command line. If anyone needs to know how just ask. Have another Server, not integrated, that's running ESXi or something. There you should have another DC running, with DNS, DHCP, Directory Services, etc. That way if you need to bring the System i partition down, you still have something of an infrastructure, and you don't really need to back it up.


Now for VCB you need another Physical integrated server, as for setting it up, read the redbook, they did a great job. http://www.redbooks.ibm.com/redpieces/pdfs/sg247408.pdf


I learned another nice little trick through this redbook. To expand the C:\ drive of a VM, make it larger, link it up to another VM, then use disk part to extend it. Well guess what, you can do that with an integrated windows server too! Vary it off, make the Storage space larger, link it up to another server, extend it, then link it back to the original. It works great!!!!!


I'm going to get VCB up and running A.S.A.P., which will probably be after the new year, but as soon as I get it working I will let you know how it works.

Welcome the IBM System i

Posted by dave@NLC Sep 27, 2008

Any idea what the IBM System i is? Ever heard of the System i5? How about the AS/400? If not, you should know about it. You've probably heard the numbers about how all the fortune 100 companies and fortune 500 companies are using VMware right? Well guess what, they all have one of these old green screen machines too! And guess what, it's more than just some Warehouse Inventory system. There is a reason that all these companies have one, it can do just about everything, and I am going to make you a believer :8}.

Now I'm not about to write an essay on why the System i is so great, but if you keep reading my posts, you will get why I'm so excited right now.

So how does VMware fit in with the System i? Well in a nut shell - The System i (which a lot of big companies have) can act as an iSCSI SAN, and you can boot IBM BladeServers and IBM System x Servers from this SAN, and have your shared storage too! Why is that so great? Because the IBM System i is one of the most reliable pieces of hardware on the planet! Because your company probably already has one! Because you can have a great backup and recovery platform! I could keep going, and trust me I will on subsequent posts, but I want to keep you interested, and move on for those people who already are experiencing the joy of this technology.

The big news - IBM announced during VMworld that ESX 3.5 is now supported on System i Integration. Here is the link to the site that explains it all. Starting with i5/OS version V5R4 ESX could be installed but only 3.0.1 and 3.0.2 were supported. It looks like this is still the case and as of this second, I am running ESX 3.0.2 build 52542 on one HS20 Blade and ESX 3.0.2 build 61618 - I'm just testing stuff, that's why I have 2 builds. I got all this going when we were at V5R4, but we have since upgraded to V6R1 - YAY!!!:D Shared storage is supported! And while I was in Vegas at fabulous VMworld 2008, ESX 3.5 is now supported. So now I need to upgrade to ESX 3.5 and build my HA and DRS Cluster. I can't wait! I'm glad to see IBM making the commitment to support VMware on this platform, the next step is for VMware to run natively on a Power System LPAR.

So here is a quick rundown of the hardware and software:

IBM System i5: Model 520 - 0595 Expansion Unit with 6 146GB 15k drives. 1 iSCSI HBA (soon to be 2). O/S V6R1

IBM BladeCenter S Chassis

2 - IBM BladeServer: HS20 Blade - 2 Dual Core 2.66 Ghz Intel Proc. 8 GB RAM. QLogic iSCSI HBA. O/S ESX 3.0.2 (soon to be 3.5)

I have VirtualCenter Server 2.5 running in a VM

That's all pretty basic stuff, but when I need to back everything up, the i5 does it for me. We have an LTO3 attached to it, and it backs up everything running on the i5 (Domino, Content On Demand, WebSphere, and now VMware)

Next weekend I am hoping to do the upgrade to ESX 3.5 - wish me luck! I'll be posting after the upgrade.

This is all about my experiences running ESX on IBM BladeCenter and System x integration with IBM System i
