The other day whilst trying to resolve a pathing issue with a blade chassis. I noticed some CRC errors in one of the Fabrics.So I'm now in the process of setting up Brocade Fabric watch (yes you do need a license for it) to monitor and alert me on these errors.Fabric watch goes a bit deeper then the Webtools event view will show you , and anyone out there running Brocade switches should turn it

So it was my 30th a few weeks ago , and on the wish list was to grab myself a Mustang (I got my ESP when I was 21)But with all the dramas with banks etc , I had to put it on the back burner. Anyway my sister and mum got me the next best thing. A ride in a 65 coupe which drop me off at the bday venue.

So if you have multiple SAN's and you add a brand new SAN into your ESX environment , and you've done a LUN rescan via Virtual Center , and via esxcfg-rescan and you still don't see the storage.Reboot your ESX host as your HBAs Bios will then be reset ( I'm thinking this is something to do with it getting its SCSI id sequencing re-ordered). And then your Vmware guys will be presented with

So I got an offical answer to my question from Vmware , as I have multiple SAN's which are presented to the ESX cluster.15 SCSI id targets16 hba's per hosts (ESX 3.5 update4)256 vmfs volumes per host.

Today was all about "Performance Tuning" from host/fabric & subsystem level. Learn't alot of good tips and can't wait to try them out when I get back to work.

Today was all about ISCSI & FCOE , I've never really been such a big fan of ISCSI but today I saw the SNIA way of incorprating ISCSI into an existing Fiber Channel infrastructure. Because at the end of the day it's all about getting rid of DAS (direct attached storage) so ISCSI can solve those servers we have , sitting out in our data centers that require very little I/O access.Big thanks to an

Google have finally made a public presentation about there custom build servers , and data centers that they use.Apparently they have been running a sea container style (Sun Blackbox) since 2005.Note check out the battery mounted near the mainboard , apparently they use these instead of buying UPS.

So it seems the mighty and very cool SGI have officially gone bust. I remember my first experience with SGI back in high school , when I undertook a work experience program and I was placed with a reseller/partner.Going out to install 4GB SCSI hard-disk for all the engineers running CAD , and all the animation guys. I still have an old VHS tape of some of the stuff SGI animation could pump out (

So when your creating your SAN Fabric and your plugging in all your hosts , remember your storage array controllers also need , to be spaced across your switches.Otherwise you could end up with a single point of failure in your fabric , if your ever decide to reboot a switch for any sort of maintenance. A fabric should be highly resilient , and allow you to reboot hosts ( dual pathing software

Sun have launch there new Openstorage systems at CEC2008 Conference in Vegas. One cool think is that they now have intergrated Dtrace into the storage management tool , which now provides a wealth of information on what's going in ZFS land.

So now that Facebook are storing more than 10 million photo's on their storage , you'd expect them to be buying storage arrays/expansion trays quite regularly.Try a NetApp 3070 every week (similar to a Sun 6540 or HDS AMS500).

So it looks like Facebook have just reached the 10 billion photo's mark. Facebook have more than 1 petabyte of photo storage , and at least 2 terabytes are uploaded every day. I bet the guys at NetApp are happy with this news , seeing as all those photo's live on there kit.

So Vmware is cool and everyone know's how wonderful it is , but it can get out of control really quickly.I heard about these guys from Vmware World who have some tools which can predict future vm growth , and also the ability to charge departments who keep requesting vm'sThe guys are called Vkernel and they offer demo's which you can download and plug straight into Virtual Center.

When you create a VMFS datastore on your VMware ESX servers many administrators select the default 1MB block size without knowing when or why to change it. The block size determines the minimum amount of disk space that any file will take up on VMFS datastores. So an 18KB log file will actually take up 1MB of disk space (1 block) and a 1.3MB file will take up 2MB of disk space (2 blocks). But the

Well after we got our cluster back online and sorted after the offical patch for 3.5update 2 was released. I installed the Storage Vmotion plugin for virtual center and migrated one of my test vm's from one LUN to another , while still being logged in and running my applications.All I can say is SWEET !!!!!!! my plan's are to get another tray which I will set aside for Storage Vmotion and

There seems to be a bug in the latest release of Vmware ESX 3.5 update , which stops vm hosts from powering up.This is due to a time/date bug you'll need to roll your clock/date back 10 days on your ESX hosts to get the up and running.Vmware are working on a fix stay tuned to the downloads page for the fix

So when you have to rebuild/upgrade your Virtual Center don't forget to add your VCB user at the top of your cluster , which will allow the VCB user to mount and snapshot the VM's your trying to backup.The permission will inherit all the way down the cluster through to the hosts so you should only need to apply it at the top level.

So I've got a few Vm's which are getting backed up via VCB via a Commvault Proxy (file level backups only). And I must say when it breaks it breaks wonderfully , troubleshooting it can be a tedious task , here are some things to check..1. Make sure your HBA's have the lastest drivers.2. Make sure your ESX Cluster has the latest patch's3. LUN Masking and zoning information are correct ie the VCB

I've been spending a fair bit of time reading up on ZFS and came across a term called the "RAID 5 Write Hole" and this is what it means , explained from the father of ZFS Jeff Bonwick. “RAID-5 (and other data/parity schemes such as RAID-4, RAID-6, even-odd, and Row Diagonal Parity) never quite delivered on the RAID promise – and can’t – due to a fatal flaw known as the RAID-5 write hole.

This is cool it turns opensolaris into a Fibre Channel target and then use ZFS to export LUN's to your hosts.It's got support for ISCSI and then reckon by the end of the year FCOE. You can check out some of the demo's at the opensolaris project Commstar site.

This was from some guy who was interviewed at last week's Storage Networking World. A storage manager for a health care firm said his boss sent him to SNW in part to learn all he could about Fibre Channel over Ethernet (FCoE). And what did he learn? "We'd have to work with the network guys," the manager said, and who did not want to be identified for obvious reasons. "And we hate those
