    Spindle count vs. Speed vs. Size

    I am preparing to purchase a SAN and continue to run into an issue regarding SFF SAS drives. To put it bluntly... they are limited as of right now when it comes to speed compared to size so the question then becomes "size vs. speed vs. spindle count". Here's the break down (sorry for the...

    SAN 101

    SAN disk performance depends on many factors. Like wether the disks are SAS or SCSI, the disk speed, the spindle count, Raid level, and the amount of LUNs/Arrays. If for example you have a database, 300 GB in size, having 6 x 146 15k SFF SAS drives in a raid 10 connect via 4G FC would give you...

    SAN 101

    My enviroment is solely Fiber and for a quick answer... yes fiber is more expensive than iscsi. If just starting out with a san and high performance is not a must than stick with iscsi, save the budget. If you plan on running services like virtualization, exchange, sql, or VDI than fiber may be...

    Random jumping of system time jumping on one of our VMware servers

    Have you tried to adjust the time settings with in the bios of the esx host. also I would check in the vmware tools to see if the guest is set to sync with host or not and also verify the correct time with in the guest bios. In my network I do not have the guests grabbing the time from host, the...

    Email Encryption Solutions

    Sorry this thread turned into an "advertisment", at least after reading over it it looks that way.... this was not meant to be. I am sure there are many other vendors, we just found that this one best suited our needs and they specialize in the medical industry. John Sorensen Network/Systems...

    Email Encryption Solutions

    As for encryption level it is AES which is Fipps compliant, sorry misread the question Zix uses different types of encryption depending if both endusers are using zix or if one is and the other is not. The main method they use is escrow encryption where the public keys are stored at their...

    Email Encryption Solutions

    We have been looking into email encryption solutions and have narrowed it down 2 different companies, ZixCorp and AppRiver. I am wondering if there is any one out there that can give me real world insight on either of these or if any one can suggest a different solution. Right now we are...

    Thanks, I will give it a try. We use disks mainly now but sometimes helpdesk needs to restore files from tape and they always forget about the whole locking issue. Thanks. John Sorensen Network/Systems Admin http://it-john.com

    PS 4.5 server joins Ad domain

    Joining a domain after Citrix is installed can cause many problems all the way from premissions to TS licensing. I tried this once in a test enviroment and gave up shortly after and reinstalled citrix after joining the domain. I would back up your configurations, reinstall citrix, then restore...

    Long Back Ups

    One thing that will slow down any backup no matter the connection is not the size of the files but how many files. 100,000 10k files will take much longer to backup then 1000 1M files. John Sorensen Network/Systems Admin http://it-john.com

    Corrupt Messages Hanging Mailbox Restore?

    restoring exchange is a pain. It sounds like your restoring from a brick level backup... from past experience that not usually a good thing. If you have a full backup of the actual message store I would restore it to a recovery store then perform a merge. Assuming you have a non-brick level...

    copy of a VM

    One exellent thing about VM's is the compression. A 30 gig VM could easily compress down to 10GB or even less. John Sorensen Network/Systems Admin http://it-john.com

    Device Locking?

    I have had the same problem and never found a solution and gave up trying. This has been an issue for many years now. we've since switched to removable drives instead of tapes. Less of a headache. John Sorensen Network/Systems Admin http://it-john.com

    Start virtual host via commandline

    Have you ever thought of just removing the shutdown option from the windows guest all together. Thats assuming they are working on the guest and not the host itself. If its necassary to actually reboot the the guest via esx command then create a cron job to reboot the server every night at a...
