Dual bay JBOD integration: Volumes - Simple striped split vs vs

The first option that I need to decide now is not put in shape, but rather if I want to set up as a Simple Volume, extending on Volume or Volume aggregated by bands. I demand to know: at what is Spanning and what is scratched? And besides, what is used for Simple? I know that I can get this information, but if you can relieve me of plowing through the mountains of unintelligible English composition work, so, I would be grateful: namely, what is the difference between a VOLUME and a PARTITION? and what it means to "mount" a volume?

I have decidted to try an answer to these questions you asked, although I considered a risky business. Use of the Word may differ widely and wildly. I decided this because I was surprised to see a paragraph that uses the colon properly and correctly punctuated ' to know '.

I start at the end: VOLUME and PARTITION. If the technical use of the terms in the jargon of computer geeks was the English standard, the PARTITION would be the place or address on the media which marked the end of a data structure. Similarly, the VOLUME would be data locations or addresses to which the data have been recorded. It is similar to the WALL and the ROOM. Use of the techniques of the terms did not differ much. When we talk of a PARTITION, we refer to a data structure that resolves the type, position and scope of a storage container. When we talk about a volume, an end to the storage location that have been defined for the storage of the data. Often, a drive letter is assigned to the volume. It is then a LOGICAL DRIVE.

Note that many people uses the term PARTITION when they do in fact refers to the space between the partitions, actually a volume.

It starts to get confused when you start under division in the PRIMARY and EXTENDED PARTITIONS. Suffice it to say that a primary partition refers to one set for its possible to maintain an operating system. He was confined to a volume that has been assigned a drive letter. The score of exrtended was intended for the non-executibles, i.e. data. Several volumes could be created within the partition, and more than one drive letter is assigned, one for each volume that is created. Each volume is a logical drive. Now-a-days, the distinction between primary and extended is blurry in use and (worse [?]), some operating system installers will allow you to install the operating system on an extended partition.

Now, back to Simple, Spanning and striped.

Simply referring to the fact that the entire volume is on a physical drive in either a primary partition or scope and size is fixed.

Extending on refers to the fact that the fact that the partition is set to start on a physical disk and continue on one or several others.

Striped refers to the fact that the contoller will deliberately write parts of the stream in defined segments, fixed size for each of the drives that are used for the volume.

Now, to the subject of which simple, spanned, striped for use.

Extending on is used especially when you have to have a very large space to store large files. On some systems, it is used as a convenient way to increase the size of a volume without requiring large data movement. Avoiding the passage of data avoids the time delay in particular with large files and the problem of data integrity of submitting the file for read/write operations.

Interlacing is a form of Spanning. Covering appearance adds the notion of dealing with predefined segment length and balance the data across the physical disks. (I think here only to configurations using the entire disk for the game.) It is preferable to the covering simple (JBOD, for example) where data integrity is paramount. As implemented, it provides various means of correction and error detrection.

Editing refers to the process of the operating system identify the drive and placing the instructions and data structures in place to enable disk reads and writes.

My suggestions:

If you need large and contiguous storage space, use a simple volume on a large drive. If you need speed, use the RAID 0 functions and make sure that you back up critical data frequenthy. For Windows, it is probably not a good idea for most users to use the readers more of 500 GB or 1 TB per RAID 0 set. Use the 'Quality of the company' readers, drives designed to operate continuously for long periods of time.

I hope that gives you a starting point. Pease do not let it be the only place. You would be well served by reading and extensive consultations.

Now, whether or not the discussion begins.... ;-))

  • Qosmio X 500: esata and a unique display of storage RAID external disk double Bay

    Hello

    IM using external storage of Welland ME-580J dual Bay raid equipped two WD 2 TB green HDD in Raid 0.
    Using the connection on my 500 - M 2 X esata I only see a hard drive. Technology Intel Rapid Storage Technology software can see both drives and will report the correct amount of storage.

    Windows Disk Manager will see 1 HDD. I spent several hours trying to find a solution, but I was not able to find a solution.
    Access to the external storage via USB works properly, but it is slower than esata.

    Has anyone experienced this and found a solution?

    Solution to what?

    As much as I know RAID 0 is nothing but striping and you cannot use two hard drives as separate units.
    Every HARD disk has several parts/blocks and they work together.
    Using RAID 0 will at the same time access to these two hard drives and it will increase the speed of transfer rate.

    I don't have this camera and can not test it, but it makes sense to me that windows Disk Manager see as a player.

  • extension of volume on 2008 R2 space appears

    After you create a new logical drive and then extend the volume by using the disk management GUI additional space is not reflected in the console or the Explorer. However, when you view volumes in diskpart split volume shows all the space. The original logical drive was a dynamic disk and the new logical drive was a GPT.

    Someone at - he encountered this before and know a solution short of formatting?

    This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)

  • Comparison of BPEL and ODI for integrations

    Hi all

    We expect the integration of two different versions within oracle applications. We evaluate the component of technology to use (ODI VS. BPEL Oracle Data Integrator).

    * There are two types of data that need to be synchronized between these two. A type is reference data (for example - items, suppliers) and the other type is associated processes (purchase orders, orders). Reference data sync-up should not have any intelligence to be built in the process, since it is mainly the loading data. ODI seems to be a better candidate for reference data sync-up
    * Sync-up associated process would require intelligence to be built in the integration process. BPEL seems to be a better candidate to do this. However, this can be achieved even by using ODI since we can execute some PL/SQL APIs or call ODI web services. The required logic can be kept in PL/SQL or web services.

    Can you please share your thoughts on the advantages/disadvantages of the use of ODI VS. BPEL (in terms of volume of bass vs a high volume of data and the impact on performance etc.).

    Thank you!

    Please refer to this http://www.oracle.com/ocom/groups/public/@ocompublic/documents/webcontent/018850.pdf white paper that describes what type of design model to adopt.

    In general, if the volume is too high, and the performance is very critical, then choose ODI. However if you want to have all the benefits of loosely coupled SOA integration, volume are not that high and there is treatment of activities it takes to arrive before the data makes it to the other side, use PIP of the ABC of the AIA connector architecture.

  • ReadyNAS probably 3-series

    Hello

    I plan to upgrade my ReadyNAS Duo which has served me well for 5 years running 2x2TB in Raid 1.
    Consider buying 2 or 4-Bay (or even 6-Bay hope not) NAS and it's for home use with small office.

    I have questions about the advantage of the separation of the data on different disks
    or more software division in volume and proportion of providing enough separation.

    In general, I need on the NAS for years to come
    A: Archived data - photos, media, etc. - accumulate by the time thread doesn't change - about 1.5 GB more
    B: Backup of Mac-3-4 - need about 1-to - change as do backups
    C: shared folders in LAN - need about 0.1 to - change a lot
    D: shared folders externally on internet with corporate clients - need about 0.2 to-change much
    -need for encryption and security
    E: - web page - TB 0.01 or if - need for security of the internet etc.

    Today I have A - C only, but consider expanding the use with D and E with the new NAS
    The old Duo likely will be the new backup destination.

    Questions (after reading briefly to the Readynas software manual 6.2):

    (1) allowing the protection bit decay is mainly interesting for A and possibly B
    If this was typically 2 diska raid1 and physically separated from the other 1-2 disks (for C - E)?
    Hear that maybe he should not be activated when the data changes all the time
    because that would lead to the fragmentation of the disk, but I may not understand it.

    (2) the activation of the encryption for a part D (for business sharing via internet) is it possible? and if yes
    recommended only for a disk full? or with a separate volume on a disk enough
    who is otherwise not encrypted?

    (3) security against non friendly internet access. Look for a web page or two on the NAS
    but worried for what it opens to attacks from outside. This help in any way to
    get that stuff on a separate drive? or enough separate volume?

    (4) I know that the volume can be split on shares and each action can be password protected
    and if I actually work today. Is there an advantage to divide more physical on separate disks
    or part of separation is enough? If a system of 2 bays with units of A - E would do anything
    the same integrity, security, performance?

    (5) I read in this performance drop checksum and inauspicious rot protection manual.
    If I have I have 2 drives configured raid1 and divide it into two volumes with checksum and bit-protection
    activated and the other will be without, they have then different performance? Or I have to
    have the volume without checksum and bit-rot-protection on a separate drive for the performance gain?

    (b) same question for the fragmentation of the disk?

    (6) the last question is the limitation to 4 TB 3-series disks one hardware or software, i.e.
    a future upgrade of the OS 6 will open for larger disks?

    In General, I think not performance is an issue. My focus is mainly on the integrity of the data and
    Internet security so I opened to access internet option D and E above.

    The questions cover a wide range and would also appreciate a partial answer.

    Thank you

  • Impossible to install secondary os

    I installed windows 7, I want to install windows 8 on the same drive, another drive, I have 30 GB unallocated space, I am unable to create this partition that requires the installation of secondary operating system. Please help me to create the primary partition of type required, dynamic, simple, basic etc. I tried to create the front partition, but after creating a volume simple secondary os can be installed on an empty dynamic score.

    Looks like that you converted your 'Base' for 'Dynamic' drive after installing Windows.  Your disk unallocated space must be contiguous if you want to even give it a try, quit frankly Windows installation on dynamic disks is a huge pain and you are going to have a hard time doing this on your converted drive, you can end up losing the entire dynamic disk and all your data if you try this on your current drive.  I suggest you to install a second hard drive in the computer if you have an available drive Bay and just install it on a basic MBR disk.

  • Inspiron 620 RAID 1

    bought an exact car/model/size of the disc that came with the existing system. I now have 2x1To sata drives. I went on the Disk Management snap-in, initialized disk 1 (new).

    Disk 0 indicates the partition OEM 39 MB, GB 916,66 parition of OS (C :) and 14.81 GB RECOVERY partition. I know in Linux that I could just copy the partition table more new disc and create the table with mdadm.

    On disc 1, I go to properties and there is no such thing as 'New mirror volume', and other raid (striped/split) options are grayed out.

    I don't understand why I can't mirror disk 0 disk 1 and do with it. What gives?

    I just did some research and apparently raid 1, family windows premium does not support, I have to fork over a bit of $$ to upgrade for the privilege of this. What a joke.
