    When we talk about storage management, there is a high probability of developing problems over time. Bottlenecks and hotspots can exist in many places in our storage environment, including arrays, controllers, and disk drives.

    If the server environment is virtualized, there will be more challenges in the performance of the storage due to excessive allocation of resources, storage abstraction (Storage Abstraction) and the dispersion or Sprawl of the virtual machines making it difficult to diagnose IOPS spikes and their given contention the dynamic nature of virtualization. You can also take help from experts like Salvagedata, they are helpful to provide you hdd recovery, storage management and many other services.

    Point prior to good storage management

    There are several components in the storage layer that affect the performance of this system. These include the array levels, the number and type of disk drives in an array set or volume group, the type of drives and their performance capabilities, as well as the host server front-end ports and the back ports.

    Problems Abound how can Virtualization and Storage Administrators Cope with them?

    To achieve this, we have 5 tips so that you can optimize your storage management, helping you identify storage I / O performance problems. These are some simple administrative actions that we can take to avoid the most common performance problems:

    1. Consider changing the RAID type

    RAID has two clear benefits: better performance and higher availability, which means it goes faster and crashes less often:

    • Performance: Performance is increased because the server has more “Spindles” to read or write when accessing data from a drive.

    • Availability: Availability increases because the RAID controller can recreate the lost data thanks to the parity information.

    You can change the RAID type of logical drives based on your storage data and your budget. You can use RAID-10 for high performance anywhere, but it may be more expensive. If you have budget constraints, you can use RAID-5 for large database volumes, RAID-1 or RAID-10 for database log volumes.

    2. Replace your Old Disk with SSD

    Many companies are considering replacing existing hard drives with Solid State Drives or SSDs, or using SSDs to increase their cache. SSD is a great piece of flash that makes data access almost instantaneous. With no moving parts, the SSD helps reduce access time, lower operating temperature, and provide faster I / O speeds.

    SSD helps to expand the cache, which allows to accelerate all I / O requests in the array, also helps to move data dynamically between different disks and levels of arrays, this translates into an improvement in performance.

    3. Reallocate the I / O Load on the Disks

    When different workloads share the same disk, it can cause interference by causing the disk head to travel back and forth between different locations based on work requests. Especially in a multi-disk system the read / write data can be very time consuming.

    Data reallocation separates interfering workloads by moving it to other disks, where they will cause less interference and avoid hotspots. Remapping also helps with defragmentation of data by organizing stored data sequentially so that when a read operation is performed, data retrieval is faster.

    4. Upgrade to a Larger Cache

    The disk cache contains data that has been recently read, and increasing the disk size improves read / write performance and eliminates I / O performance bottlenecks.

    5. Plan well and add more Physical Disks

    This is the inevitable scenario in any storage environment. No matter how many disks you add to expand your storage capacity, they will eventually run out. Keep the following recommendations in mind when adding more disks:

    • Be aware of how many disks an array can have and how many are currently installed.

    • Consider the IOPS possibilities as well as the disk storage capacity.

    • Understand storage content, classify data based on criticality and usage, and choose storage expansion option based on this.

    • Instead of adding more disks, you can also choose to increase the storage tier of existing ones.

    • Make sure you have storage capacity planning and predictive analysis of how it will be used. Add discs only when necessary.

    Final Considerations for your Storage Management

    While these are effective tips for improving the performance of your company’s storage management, the biggest problem is controlling the environment and identifying the bottlenecks that appear so that we can avoid performance problems. You need to have optimal visibility into the machines of the network elements and the storage as a whole.In this case Salvagedata will a great choice, they are fully expert in hdd recovery, storage management and in raid 0 recovery and many other services they provide.
