    HP MSA2070s configuration

    I stand corrected, there was a MSA2070s in the plans. Any reference to this is gone from all HP partnumber databases as far as have been able to determine. I found some information about the MSA2070s and MSA2060s being scheduled to be introduced end 2007. Guess that never happened. I've never...

    HP MSA2070s configuration

    There is no HP Storage product called MSA2070s. The four port module and the "s" at the end would suggest it's a SAS model. MSA2012sa perhaps. How many diskslots does it have? How many rack units high? Are the disk 3.5" or 2.5"? Is there a partnumber anywhere on the box? Should be in a 6-3...

    oh dear, my raid no longer works

    Since you had two 500 GB drives that appeared as a 1 TB volume in your computer, it means they were configured in RAID-0, with no redundancy at all. Short answer: Your data is gone. Longer answer: The entire volume is split in chunks of around the 64 kB mark. No way to get that back, the...

    Query to report what numbers in a range do not exist.

    I have a database with storage system configuration. Table "Array" contains names of storage subsystems. Table "Host" contains hostnames in each storage subsystems. Table "LUN" contains LUN numbers used by each host. Host references Array, and LUN references Host. This seems to work as...

    passing data from a select to an insert

    Thank you for you kind assistance gmmastros. I think I'm starting to understand the concept of joins. In reality, I think I would have a long time ahead of me using your outlined approach getting my head around it. I solved the problem by using a cursor and stepping through the insert. The...

    passing data from a select to an insert

    I've left work for today, but the insert statements actually works. I don't get an error, although I did get the errors you mentioned until I got it right. It does what I want. However, I obviously don't want to type in the values manually, I want to use the output from the select statement with...

    passing data from a select to an insert

    I work as a storage technician, and I'm looking for ways to automate some of the tasks. SQL development is not in my job description, be gentle. I have tried to model a database following the procedures and layout of a storage array. One storage Array is identied with it's serial number. There...

    MSA 1500 rebuild array

    The disk should be seen immediately, and the background initializaion is something done during normal use. Are you sure you set the access control list correctly?

    SAN connection to network

    The ethernet port on a Silkworm switch is just for management. It's just a node like any other, with an IP address and a MAC address.

    New SAN help

    They connect via SAS (Serial Attached SCSI) directly to one host. Quite right, they can only be connected to one server. They're made for HP ProLiants, but it should work with Poweredge servers. You might however want to look into what Dell offers in disk shelves, not too familiar with those.

    New SAN help

    If your total storage is 1 TB for all six servers combined, why not just buy a disk shelf for each, or at least the ones that need a lot of space? Just as an example, an HP MSA70 and a suitable smart array board will give you 25 SAS disk slots and quite decent performance. Probably on par with...

    Sustained throughput in a Legato NetWorker environment

    Ok, I used the term dedicated in meaning a server that is a storage node only, and is not running any other application(s). I find the NetWorker terminology confusing, but I do mean from a licensing viewpoint a full Storage Node. Retention is for the most part only a month, but indeed it's a...

    Sustained throughput in a Legato NetWorker environment

    I'm toying with a scenario where I want to backup several terabytes daily in a NetWorker enviornment. Some facts, Clients: several hundred of many different OSes Data volume: about 20 TB needs to backed up during a lot less than 10 hours, I'll probably aim for 5 hours. That's 4 TB/hour or...

    SATA and Logical Drive size

    SCSI is limited to 2TB (2^32-1) bytes. You'll have to create two luns 1,5TB in size and create a volume set in Windows.

    Mixing 10k drives and 15k drives in HP EVA 5000

    You can install mixed speeds and capacities of drives in an EVA. However, it's best practice to keep them into seperate diskgroups. Then again, it's also best practice not to create more than one diskgroup, hence it's not really a good idea to mix speeds and capacites. You'll end up with...

    performance

    I'll just make it short for now; measuring speed in this context using MB/s is wrong in more than 90% of the real-world scenarios.

    performance

    Define "fast" in your context. How do you measure the speed, in what unit?

    Brocade 2800

    env is environmental, PS002 I'm fairly sure means Power Supply 2. The switch has detected a fault with one of the power supplies, which is either faulty in itself (rare) or the power cable somehow has gotten loose (more likely).

    Stage between storage nodes

    My claim was "...Although I see this as technically possible in NetWorker, since it's possible to clone between storage nodes, how feasible is it?" I claim it is possible, not that it's not possible. And you agree it's possible. My question is really how feasible it is from a management...

    Stage between storage nodes

    I might have asked this before, but I've been getting mixed answers from different people, so I thought I'd ask again. This time with a more detailed scenario: Within the same zone I have several remote sites with storage nodes. On those storage nodes I have direct attached disk, to which I...
