Interviews for Top Jobs at RAID

Account Executive Interview

ApplicationI applied online.  The process took 2 weeks. I went through a painful and deceptive interview process at RAIDInterview. After a brief call with the hiring manager on Tuesday (the same week), I scheduled a meeting to be on-site on Friday. When I arrived on-site, I waited at least 30 minutes before anyone actually spoke to me, sent into a conference room, where I waited for the hiring manager for about 40 minutes. As far as I could tell, the most recent “next step” agreement did not match my expectations. received emails with subject lines like “hope we are not misleading you” and “sorry, I was caught up doing ‘xyz'” They definitely didn’t maintain the pace that seemed to be established, and I believe they misled me. Horrible feeling always ‘on hold’, waiting for next communication. Finally met co-founder ( by phone ),. again, mis-leading. They were given a written offer that would be delivered the day after the last phone interview. I received a lengthy email at around 9:30 pm on the Friday the offer was promised, with justifications about not being able to make an offer because a “sudden” candidate became available and they needed more time to vet out and “digest” everything. There was no communication with me at all on that day. The first person I spoke with, the hiring manager’s longtime partner, informed me that there was a lot of turnover (which was what he disliked most about working there), and I could understand how difficult it must be to keep employees there. They painted picture of pretty crumby environment. I knew better than to spend my time with them in vain. The interesting thing is that when I spoke with this company a few years ago, I had the same “deep-seated” impression that the environment would be similar to a boiler room. On this second attempt, I made an effort to set that aside, but it kept coming back to that. Candidates,. be VERY CAUTIOUS !!!!!! Personally, it was a terrible experience.

The hiring manager scheduled a phone screen, which was followed by an on-site interview a day or two later (there was no HR or talent acquisition stage here because this was a small company). Both of these interviews went well in my opinion. The in-person interview included a thorough tour of the workplace and an opportunity to view some of the company’s products. I was promised at the conclusion of the interview that I would hear back from the company within a few days, but I haven’t heard anything. css-1e8g7ps{border:none;outline:none;background:none;cursor:pointer;color:#1861bf;}. css-1e8g7ps span,. css-1e8g7ps svg{color:#1861bf;}Interview Questions. css-1bzau0h{list-style:none;white-space:pre-line;}Describe your Linux background. css-12cchq2:before{content:”↳”;color:ui. grey[‘500’];display:inline-block;font-size:18px;margin:0 12px 0 0;position:relative;top:3px;}.

Increased redundancy Increased data availability Higher READ/WRITE performance in some RAID levels Higher Data Throughput Higher Reliability Higher Data Security: Most RAID levels provide data security for the array’s stored data through the use of redundancy. In this way, the data at the array can withstand even the complete failure of one hard disk (or occasionally more) without any data loss and without needing to restore any data from backup. A major benefit of RAID is its security feature, which is also likely the reason that more RAID arrays have been introduced than any other type of array. Except for RAID level 0, all RAID stages provide some level of data protection, depending on the specific implementation. Fault Tolerance: Compared to a single disk, RAID implementations with redundancy offer a much more reliable universal storage subsystem. This suggests that there may be a reduced risk of the garage subsystem failing completely as a result of hardware mishaps. (At the same time, however, the delivered hardware used in RAID increases the likelihood of having a hardware issue of some kind with a specific component, even though it wouldn’t bring down the storage subsystem; for more information, see this comprehensive discussion of RAID reliability.) Improved Access: Access to information is referred to as availability. Good RAID systems increase availability by providing fault tolerance and providing special capabilities that enable quick recovery from hardware failures. See this discussion of superior RAID capabilities as well as this discussion of RAID reliability. Increased, Integrated Capacity: By combining several smaller drives into a single larger array, you can upload their combined capacity (although most implementations lose some of the total capacity due to overhead or redundancy). Applications that need a lot of contiguous disk space are now possible, and disk area control is also made simpler. Let’s say a large database requires 300 GB of space. Unfortunately, no hard disk manufacturer produces a power that nearly that large. You could install five 72 GB drives into the system, but you would then need to figure out a way to split the database into five pieces, and you would be stuck trying to remember what had been. All RAID implementations offer this “combining” advantage, though the ones that include redundancy of path “waste” some of the gap on that redundant data. As an alternative, you can install a RAID 0 array containing those five 72 GB hard disks; this may appear to the working device as a single, 360 GB hard disk. Last but not least, RAID systems improve performance by enabling the controller to take advantage of the capabilities of multiple hard disks in order to circumvent performance-limiting mechanical issues that are common with individual hard disks. Various RAID implementations improve overall performance in unique ways and to different degrees, but they all do so in some way. For more information, see this comprehensive discussion of RAID performance issues.

This is the most efficient RAID configuration that can be found in a computer device. To manage an array, a hardware controller card is typically needed, but some computer operating systems can create these through software. This method holds record redundancy using a parity-based striping pattern. A RAID five array must have at least three drives, and they must all be equal drives for satisfactory performance.

The “different OR” or “XOR” logical operation is typically used to finish the parity calculation. You may be familiar with the fact that the “OR” logical operator is “authentic” (1) if either of its operands is authentic and false (zero) if neither is. The unique OR operator differs from “OR” in that “XOR” is false if both of its operands are authentic; it is “real” if and best if at least one of them is.

RAID 0+1 is a hybrid form of RAID that some manufacturers have used to try to combine the benefits of the two versions. Usually, a system with at least four hard drives is best for performing this on. After that, it combines the mirroring and striping techniques to provide performance and redundancy. The data could be striped across the first set of drives, which could be in use, while the second set of drives could be a duplicate of the data on the first two drives.

The crucial term for data storage plans that divide and/or reflect information among a few hard drives is Redundant Array of Independent Drives (or Disks), also known as Redundant Array of Cheap Drives (or Disks). They offer increased information reliability and/or throughput, depending on the plan. RAID is a technique for storing the same data across multiple hard disks in additional drives (thus, redundantly). Question 2. What Are The Advantages Of Raid?.

RAID (redundant array of inexpensive disks)

  • The total length of an IDE cable can be only a few feet long, which generally limits IDE drives to small home systems.
  • IDE drives do not hot swap. You cannot replace them while your system is running.
  • Only two devices can be attached per controller.
  • The performance of the IDE bus can be degraded by the presence of a second device on the cable.
  • The failure of one drive on an IDE bus often causes the malfunctioning of the second device. This can be fatal if you have two IDE drives of the same RAID set attached to the same cable.
  • The drive data cable can be as long as 1 meter in length versus IDEs 18 inches.
  • Serial ATA has better error checking than IDE.
  • There is only one drive per cable which makes hot swapping, or the capability to replace components while the system is still running, possible without the fear of affecting other devices on the data cable.
  • There are no jumpers to set on Serial ATA drives to make it a master or slave which makes them simpler to configure.
  • IDE drives have a 133Mbytes/s data rate whereas the Serial ATA specification starts at 150 Mbytes/sec with a goal of reaching 600 Mbytes/s over the expected ten year life of the specification.
  • SCSI controllers are more tolerant of disk failures. The failure of a single drive is less likely to disrupt the remaining drives on the bus.
  • SCSI cables can be up to 25 meters long, making them suitable for data center applications.
  • Much more than two devices may be connected to a SCSI cable bus. It can accommodate 7 (single-ended SCSI) or 15 (all other SCSI types) devices.
  • Some models of SCSI devices support “hot swapping” which allows you to replace them while the system is running.
  • SCSI currently supports data rates of up to 640 Mbytes/s making them highly desirable for installations where rapid data access is imperative.

    Question 5 of 29 in our mock interview for a project support officer

  • How to Answer
  • 1st Answer Example
  • For organizational reasons and to identify important risks and issues, many project managers and project support personnel use RAID analysis at the beginning of a project. The interviewer is interested in learning if you are familiar with this idea. Explain how you would use it during a project. If you have prior experience with the tool, provide a few examples.

    “To start, RAID stands for Risks, Assumptions, Issues, and Dependencies. I believe it is always sage to perform a RAID analysis at the start of every project. It enables you to conduct a thorough environmental scan as you make plans so that any problems or dangers are promptly identified. Additionally, it is useful from an organizational standpoint; it keeps the project on track and gathers all pertinent issues affecting the project in one location. I would perform a RAID analysis beforehand for any project using an online tool like GroupMap, for instance. “.

    FAQ

    What is RAID concept?

    Storage technology called Redundant Array of Independent Disks (RAID) is used to increase the processing power of storage systems. This technology is created to increase the reliability of disk array systems and to benefit from the performance advantages that multiple disk arrays have over single-disk storage.

    What are the 5 RAID modes?

    RAID modeDescriptionRAID 1Mirrored disksRAID 3Striped set with dedicated parityRAID 5Striped disks with distributed parityRAID 101+0; Striped set of Mirrored Subset

    What are the four types of RAID?

    RAID 0 (striping), RAID 1 (mirroring) and its variations, RAID 5 (distributed parity), and RAID 6 (dual parity) are the most popular types. Additionally, multiple RAID levels, such as RAID 01 (mirroring stripe sets) and RAID 10 (striping of mirrors), can be combined or nested.

    What are the 3 most common RAID configurations?

    Typically, read and write speeds, storage capacity, and fault tolerance levels are used to evaluate configurations. Today, there are numerous RAID levels in use, some of which are uncommon. RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10 are the most popular RAID configurations.
