Shutting down the PC to replace the failed drive not a problem its a single user PC 2. The cost of providing a second drive for no increase in storage is not an issue. And even if only a few hours loss of data, reconstructing that can be time consuming. Does the proposed arrangement make sense in my situation? Or should I be looking at other alternatives?
I will be using 8x8tb sas hdd. Basically just looking for redundancy and not to worry about losing my files, pictures, movies. What RAID would be best? My old desktop is dead. Will I need to find a way to hook them up together to be able to get the data back? You cannot read the data of one individual drive that once belonged to a set of RAID disks.
In your new machine, the two disks must be configured identically to how they were configured in the old setup in order to access the data. There are certain disaster recovery programs that are able to recognize RAID drives. The HD cage can take 4 3. I want to install Windows Server on it. What is the best way to go about? The obvious option for me is to separate OS from data.
Install OS on these two 2. Please bear in mind that these drives are used and pulled from servers. Any better way for this? Every disk is a potential point of failure, so using 24 small disks which 4TB drives meanwhile are is not necessarily the most secure starting point. Consider using fewer but larger drives. This will also be slightly cheaper as an 8TB drive costs less than 2 4TB drives. The empty slots in the enclosure can be handy for future expansion. If you can leave an empty slot between adjacent drives, that will also allow them to run a bit cooler.
Even with RAID 6, the risk of failure with that many disks is quite high. He may work on a project for a few weeks and then will deliver the product. What type of raid system might be best for an application like that?
RAID 0 with a back up of the file. How much capacity will i actually have afetr configuration. If not suggest me a solution for this, because i only have three M2 slots in my notebook and would want both the benefits of Speed And Security of the Raid Levels. You should use 1TB in each of the three slots, and use Raid5 to both benefit from speed and security. Data and parity will be spread across 3 drives, so that reading and writing is done to 3 drives, and 1 is allowed to fail. If it does, it needs to be replaced.
I have a drive that failed in a RAID 1 configuration. I need more space so I was going to get 2 new bigger HD. Now is it advisable to use 2 identical drives or could I use a high performance desktop RPM as the main drive and get a cheaper NAS drive for the mirror?
Both would be the same size. Any issues with doing that? In RAID 1, write speed is as low as the slowest drive. Only if you want a better reliability in the way that different drives have less tendency to fail at the same time. Hello, I enjoyed you info. I could use your expert advice on a Hard Drive situation I have. With alot of data and Pro tools tracks.
The drive stopped working one day. I removed the gig Hard drives and tossed the housing. I stored them away for safe keeping hoping to recover the data one day. He tested them and they still work but no data. How do I marry them again to work as one external drive?
I am running Windows 7. Any info would be a great help. This would be a lot more simple with a Linux system, because it has much better facilities for accessing drives other than as filesystems. Ask around your circle for someone who has Linux knowledge. Whatever you do, do not put the drives into a hardware RAID device and install them as a striped pair. The RAID controller is likely to overwrite some of the data on the disks, as soon as you do this.
I was amused when this popped up on Google. You do have a point that for completeness both versions should be included, so I updated the page. Thanks for the feedback! This was useful since at the time hard drives were VERY expensive, especially as size increased. It was cheaper to create a large RAID array inexpensive of disks than it was to purchase a single drive with the same capacity. I would like to find some documents on what each RAID configuration would need as a minimum from the server it is running on.
It worked for documents, but not for large or small amounts of data needed to be drawn. Its hardware was very subpar, and although it makes a big deal of being a quad-core, its limit was mhz, which is not as fast as current high level cell phones. The tech who set it up could not see how a RAID 5 could slow it down, I just wanted to eliminate redundancy altogether except for my manual but effective backups at night and lunch. In my effort to procure money from my manager I rebuilt our old server with new cooling and clean install, as well as RAM improvement to 3.
The D-link would render my mock up map in seconds, the old server took 7 seconds. This D-Link should only be used for homes or documents. Large datasets are useless, write speeds are terrible, as are read. It was a nightmare. And the fact that the old 32 bit with an unreal amount of use was made to look like a giant rack system comparatively was not enough to get any money for a new server.
A City Planner has not enough skill to set up a monitor, jerk move on my part, but deserved. Amazed to find City Planners have no mathematical skills, coming from Engineering I assumed they were similar. Point is, Planners are useless managers and have no skills.
And I could go on! Raid systems are to protect data and that is given! How one likes to protect data is decided on the conditions and requirements. To make it short; to be secure at home, get a cloud storage which is slow but very safe as the large service providers take this very seriously but it is a bit expensive or buy a back up drive from Western Digital, Seagate etc.
In my case, I want my data access to be fast, failsafe and accessible from anywhere in the world! What do I do?! I get a raid system like Raid 5 or 6 with 6 drive bays, a back up system to automatically back it up and get a service provider to have them connected to internet like it is in the cloud but actually it is a private cloud.
One can also have a cloud storage lage enoufh to replicate the data at home which is stripped with parity and backed up. It sounds like overkill? What is parity? It is the end result of calculation of data written on a disk as in 1s and zeros. The result is also in 1s and zeros. You write the result in the parity section which is also distributed so that it also has parity information.
It took us haf a day in class some 20 years ago to understand and learn but you do not have to go through that. Imagine there are 5 disks. Data you lost on a drive is missing but like a puzzle, you have all the surrounding lines that are continuing at the other side of the missing piece. You also have the colours. More, less, this is the idea.
This is a nice write up, but missing some basic logic. Other than that, it has the best performance and redundancy of all RAID levels. I currently have 11TB of [ictues on a 12 TB drive. The leader of a party can convert the group to a raid by clicking the "Convert to Raid" button in the Group window. At this point it becomes a "group of parties" with up to 8 parties, each with 5 characters.
The leader of the raid can drag characters between groups to move them to different parties; this was traditionally done to achieve some strategic goal such as distributing shamans and paladins to share totems and auras or warriors with rogues for [ Battle Shout ] but Blizzard has phased out this strategy.

View source. History Talk This section concerns content exclusive to Wrath of the Lich King. In World of Warcraft: Wrath of the Lich King , all player raids are also available to complete with 10 players. This is so that more players will get to see end game content. Even the Lich King encounter is available as a 10 player raid.
Raids are designed as activities for people whose characters have reached the maximum level. As the game does not permit further increase of skills, or introduce new abilities, the only avenues remaining to enhance a character lay in "better gear". In addition, a majority of such bosses also require the group use particular, sometimes unique tactics. While occasionally those tactics mirror those used by smaller groups, they often require things that smaller groups simply don't have the diversity to do.
Given these unique requirements, most raid boss encounters require some amount of practice to defeat. Raiding guilds are guilds that devote some or all of their collective time to playing in raid instances, defeating or practicing to defeat raid encounters. They have the advantage of being able to get to know the abilities or lack thereof of their various members, and adjust their tactics accordingly. They also have a shared investment in the success of not just that raid, but future raids as well, a feature that "pick up raids" lack.
There is some academic discussion about the concept of raids as they currently are designed in major graphical MMOs, primarily centered on how much of a player's time they consume. A typical World of Warcraft raid can take hours once the group is able to complete it, and can take much more time over many sessions to get to that point. Basically, that it can take up as much of one's time as permitted. There are, of course, extreme examples, such as a Final Fantasy XI raid that lasted 18 hours before they decided to quit.
World of Warcraft mitigates such long boss fights by adding enrage timers to bosses to ensure that a single fight does not last too long. Given the amount of time involved to be successful, there are some game developers and academics that feel that raiding can be a focus for obsession, impacting a person's ability to care about real life goals and accomplishments.
The leader of a party can convert the group to a raid by clicking the "Convert to Raid" button in the Group window. At this point it becomes a "group of parties" with up to 8 parties, each with 5 characters. The leader of the raid can drag characters between groups to move them to different parties; typically, this is done to achieve some strategic goal such as distributing shamans and paladins to share totems and auras or warriors with rogues for Battle Shout note that this is no longer needed in current patch.
