Super High-End Club (storage mile high club?)

Oh, I can see the eyes rolling.  Two blogs by me in one day.  Hey, its an unwanted (if there is such a thing) holiday and its cold so I just vegged out. I rarely visit other bloggers sites and I really need to do it more often.  Chris Evans' site is the exception as he writes what I somehow need to know.... and he uses Tuning Manager as well.  If only he had HSSM as well. So today I visited Tony Pearsons' site just to see what goes on in the world.…

Hotmail, Gmail et al, how do they do it?

I did my normal once a month check of gmail today and noticed I have 4.6 GB of space and it is growing every minute.  We are moving to 1 GB mailboxes at work and that is going to chew up huge amounts of our most expensive storage as everyone classes email (of all things) at mission critical.  A lot of people are already complaining about 1 GB not being enough and asking for double if not triple the size.  We have less than 10,000 mailboxes so this leads me to gmail and similar…

Is there another way of saying you don't care?

I am sure we have all had horrible things go wrong and then we look forward to an apology of sorts from the vendor.  I have been known to get a bit annoyed when something goes pear shaped but at least its good to get some sort of "I'm sorry, I will do a full investigation...etc.. etc.." I did something bad once on a Sun 15k where I managed to pull a system board and a bolt inside sort of broke.. It was stupid and I learnt never talk to anyone…

Something for everyone

Seeing as how some posters think this is a blog site that does not offer unbiased discussion, I thought I would raise something that all enterprise wanna be storage vendors have to deal with.  So please feel free to put in any discussion that you think is worthwhile especially if you are a marketing person and you would like to tell me just how good your non HDS storage is with something like this. The organisation that I work for seems to value email above everything excluding the mainframe.  So we are running Hitachi Storage Cluster with Microsoft…

Virtualisation and USP cache

I have USP's that virtualise a number of external arrays and each array in the USP has its own CLPR.  Recently I started noticing that one of the CLPR's was having a real hard time with one of the servers and was constantly destaging its cache.  It appeared that the other CLPR's were in some small way effected by this and I don't know why.  HDS seem to recommend that you should have at least a CLPR for each virtualised system and it might be best practice…

LUN (or data) migration.

I read the Cisco DMM literature and wished even more that I had a SSM somewhere in my SAN.  I see all the other posts comparing oranges with apples (EMC versus HDS) but never see much when it comes to switches.  Sure enough Brocade introduced the DDM a few months before Cisco introduced DMM.  I suppose I am a HDS bigot but you can mulitply that by a million times when it comes to switches.  Hopefully Cisco will pay me something to say how much I like them so I can keep in line with previous…

port queue depth - the never ending story.

I am starting to hate going overseas for a holiday.  I always end up on deaths door step and this time nothing changed.  So, I now have a week off work to try to get over this thing I got in Thailand and it is not attributed to the local inhabitants.  Only once before in my life have I been so sick.  The good side is that I have lost a few kilo's.  Surgical masks should be compulsory on all international flights. I have been watching the HDS forums (between coughing and sleeping…

300 GB 15K Drives for the USP/USP V and NSC

I got notification today about the new disks available for the USP et al. I thought it interesting that there were a couple of things that might need comment. Even though it was not really suggested, the notificaiton said: <qoute> .... due to the large capacity and the proportionally longer rebuild time for these drives, a RAID-6 configuration provides additional protection against possible data loss in the event of a second drive failure during the longer rebuild time of the first failure.  </quote> I like the idea that someone actually says it is a good…
