If everyone thinks storage is so boring, how come we always want more of it? Angus Kidman dives into the murky world of enterprise storage, covering everything from the best way to manage a storage area network to the wisdom of trying to ban USB keys and iPods. Go on -- you know size matters.

Time for a limit on storage limits

Posted by Angus Kidman @ 15:38 17 comments

We're constantly being told that storage capacity is cheaper than ever, so why do companies still insist on imposing size limits on e-mail inboxes?

There are many reasons why you might want to throw a BlackBerry across the room, but automated nag messages from the IT department certainly rates one of the highest.

A mate of mine was recently bemoaning the fact that the e-mail set-up at his workplace automatically starts sending out "your mailbox is nearly full" warnings when the e-mail file goes above 60MB.

This in itself seems pretty insane, given that his overall limit is 100MB. An equal hassle is that the same message keeps being sent at regular intervals of 10 minutes or so, thus making the problem worse by adding extra excessive messages to the inbox.

Leaving aside the questionable justification of having that particular notification schedule, it's a bit of a mystery why any company would want to impose a 100MB limit, given that you can purchase even the USB version of that amount of space for the equivalent of a couple of hours of white-collar labour.

Quite frankly, 100MB is nowhere near enough. If you're exchanging and revising PowerPoint files, for instance, you could easily consume that with a handful of exchanges.

OK, I know you could use some of Office's fancy file-sharing features here, but we're dealing in the real world, not Redmond's fantasy business vision. In practice, people still fling files around using e-mail.

After all, when consumer e-mail providers are falling over themselves to provide gigabytes of free space, being told at work that you can have a fraction of that amount is galling to say the least.

Modern corporations aren't renowned for their caring attitude towards workers, so perhaps the best threat remains a legal one.

With e-mail now constituting a core business record, imposing stupidly small limits might lead to the destruction of important business information that subsequently pops up in some unpleasant and unexpected lawsuit. Seems like a big risk relative to purchasing some more hard drive space.

  1. you're joking Anonymous -- 08/10/07

    Or you're an idiot.

    There are perfectly good reasons for imposing size restrictions on user mailboxes, especially in large organisations. I agree 100MB is a little on the mean side, but it's not completely unreasonable.

    Your outrage belies the fact you've never had to administer a system of any significant size.

    1. Hrmm... Dan Warne -- 08/10/07

      I don't think Angus is an idiot. After all, Google manages to offer multi-gigabyte capacities to its millions and millions of Gmail users without apparent system difficulty. Maybe the problem is that Microsoft Exchange cannot reliably handle mailboxes of many users at a large size reliably... but then again, Microsoft itself recommends 2GB+ mailboxes for companies running the latest version of Exchange...

    2. do the math Anonymous -- 09/10/07

      Exchange Server 2003 SP2 defaults to an 18GB information store limit. Sure it can be upped to 75GB via a registry change, but most administrators won't know that (or wouldn't do it anyway if they did).

      So divide 18GB by 150 users. Gee, that's 120MB per user - what would you make the default limit so that you can "afford" the necessary exceptions for specific users.

      You cannot compare free web-based email systems run by corporate giants with oodles of hardware, to the client/server email system run by typical small businesses.

    3. I dont think he is... Anonymous -- 08/10/07

      ...even mentioning USB storage in this sort of debate shows he has no idea.

    4. Have to agree Anonymous -- 08/10/07

      I mean cmon! I get HUGE space from Gmail - do I use it? No. 'cos I am a responsible user - nail the spam - offload - the "important" stuff to, say, Outlook, and empty the trash on a regular basis.

      Biggest threat is the users that either do not know - or give a rats arse about storage issues. I am not one of those.

  2. Because cheap != free Anonymous -- 08/10/07

    Because USB storage != fast, reliable RAID

    Because it's not just the disk space, it's the backup space, the backup window, the recovery time.

    Because without an incentive some people do no housekeeping at all. I administer about 350 mailboxes and have some (without limits) that are > 5Gb.

  3. sox sucks smaller mailboxes the better Anonymous -- 09/10/07

    compliance requirement in large companies with 30-40,000 mail users is a nightmare you have to retain the mail for 7 years to permant
    for members of the board and senior management. This can result in backups being retained in the 500-700 peta bytes range and growing. This is even with single instance storage for the same document sent to multi users. You have to be able to recover you data to be given to a number of goverment department and regulators.

    People have to understand gmail and is other flavours is not fool proof .Users are have no recourse if staff read/disminate you data or it is lost due to backup failure read your agreements. or they change the policy of retention of your mail.

    hence this is why you have small data limits

  4. My Problems are solved!!! Anonymous -- 09/10/07

    Thanks for the USB suggestion - I hadn't thought of that... I'll be getting me a few Sandisk Cruzers to stuff in our iSeries ASAP... our users will be so happy now! No idea!

    1. what a moron... Anonymous -- 11/10/07

      agree totally with this!

      i would like to issue a challenge to mr. kidman and ask him to manage a decent size email system for a month or two (>1000 mailboxes) and see how he goes with no limits.

      why must we put up with journalists who think that they are administrators?

      and i use the term 'journalist' loosely, in this case...

  5. Email not a storage system Anonymous -- 09/10/07

    Email was never really intended to be a 'storage system' so why store stuff in there that can't be searched (easily) by regulators etc. Email is the medium for transferring the information, not storing it. You need to move the mail out into something that is a genuine archive system. Not to mention the idea of trying to recover a crashed exchange private store of 18Gb....

    But then, as was said, I do have some spare USB ports....

  6. Think Again!! Anonymous -- 10/10/07

    It's not just a case of storage room for email inboxes.If you have 150 users all with unlimited mail box sizes then your backups could run into multiple media and by month end will be up to the sky.When it all boils down to it,it comes down to money and storage space for backups.Along with managability of your servers and users.If you train your users to remove any attachemnts from their emails and store them on the local machine or USB drive, then you can save a heap of room for what matters - the mail.The problem most users at a particular site have is that they don't utilise the Public drive on the site server to transfer and (temporarily)hold files so they can be viewed altered and then sent out, reducing mail traffic and bandwidth to boot.
    Don't just bag the mail admin people just because GMAIL can do everything you believe everyone should have.Its just not practical.

    which one is it?? you can't have it both ways!

  8. Has anyone thought of archiving? Michael Andrews, AXS-One -- 12/10/07

    Angus, you’ve nailed it with your last paragraph. Because at least 80% of business communication these days is via email and IM, companies do have to be careful to retain all business records for the required length of time (7 years for financial documents for example).

    There are many examples of lawsuits where companies have settled out of court because the cost of defending the case and locating particular emails on back up tapes would have been much more expensive.

    A much better way to manage the huge volume of emails is to have an archive system that moves them from the email server to an archive server with less expensive storage whenever a mailbox gets to a certain limit or on a regular interval. This is an automatic process that is transparent to the end user. On the desktop, users can still view all their archived emails, simply by clicking on a link. This means their email mailbox is not restricted at all and those nasty messages don't keep popping up.

  9. Time to grow up Anonymous -- 02/11/07

    The problem here is not undisciplined users but the above old school administrators who feel it is their job to tell them what they can and cannot do. In IT there is almost nothing that cannot be done - it is just a matter of cost. Storage of information for legal or other reasons is a business need and it is their decision, not yours. Your job is to understand the requirement and present options. If it will cost a billion dollars to give them unlimited mailbox size and the CEO says that is ok, who are you to argue?

    It is time that IT departments took on the role of solution providers (to business problems) rather than being the technology police.

    And the flip side of that coin is that business management need to take on more ownership and responsibility for the solutions they are asking for (e.g. by making cost/benefit decisions and not expecting the IT department to just supply them with whatever they feel like).

  10. WTF ?!?!?!? Anonymous -- 06/11/07

    I for one would like to work for a company/organization like Google who have an almost unlimited budget.

    Maybe then I could afford to have a server to mirror my production environment, so I could then shut down my server while I add yet another array cage

    All comes down to dollars - even banking and finance industries have their limits on how much they will spend on I.T.

    I think Mr Kidman needs to spend a few months working in I.T. to truly know how ridiculous his article is

  11. Relevant Information? Need for Balance! Anonymous -- 29/11/07

    The real issue in all this is information management.

    It is ridiculous and inflammatory to suggest unlimited e-mail limits.

    For those working in large or rapidly growing businesses who understand information and knowledge management it is necessary to educate new, inexperienced or in this case just annoying colleagues.

    Like any storage environment (not specifically IT maybe your garage or shed), 80% is garbage or irrelevant and just takes up space. Restriction along with better education and an information management policy that informs user about what is relevant and needs to be saved it the first step before you simply up the limits of you e-mail or storage environment.

    This is a company operational and process issue as much as it is an IT issue. An it can not be effectively addressed without this collaboration.

  12. Hang on Anonymous -- 14/05/08

    Hang on, and normal TEXT based message shouldn't take up that much space.

    It's these people using HTML/RTF in their messages complete with disclaimers attached to every single message and also quote entire messages back to someone just to add a five word response that are clogging up space on systems.

    As for the sending of documents within the same company, (Powerpoint, DOC and what not), it a MESSAGING system not a FILE system. You want someone to see the latest revision of a DOC or powerpoint host it on a company FILE SERVER and point the recipient to it.
