About New Bulk Pack Products
Storage Controller
Here on allhdd.com, we offer consumers like you some of the best storage solutions on the market. Our wide range of quality storage controllers contains products in the following categories:
MSA 2000 Series, Powervault, 4-Port, Poweredge VRTX, PCI-E, ServeRAID, 2-Port, Equallogic, MSA2040, and MSA2050.
A storage controller, otherwise called storage processor or array controller, is a device that regulates or controls storage arrays and essentially contains the three types of elements, including the following;
- The central processing unit,
- The Cache Memory,
- The connection of interface with the network and memory devices.
If you have multiple memory devices, our storage controllers will help create a single memory channel. In other words, our storage controllers combine the memory areas in various memory devices and render them as a single memory area to your server.
A storage controller picks out the appropriate device from multiple memory devices to fetch data when it receives a request from the server to write data. It then stores the selected devices' data.
On the other hand, when there is a request to read data from the server, the storage controller searches the location where the associated data is stored. It reads the data from the location (memory device) and then transfers it to the server.
Qualities of a good Storage Controller
In addition to reading and writing data efficiently and stably, your storage controller carries out processing tasks to complete many functions, including dynamic volume capacity allocation, among others.
The storage array's performance can be directly affected or determined by the storage controller's speed and capabilities in the advanced data center. High-speed storage infrastructure is a vital factor in storage arrays as it enables the network to send data at 10 Gbps using Fiber Chanel of 10 GbE or Gen 5 (16 Gbps).
RAID And How It Works
RAID stands for redundant array of independent disks. Suppose you intend to store the same data in multiple solid-state drives or locations (hard disks); in that case, a RAID card is an efficient means of achieving this purpose without storage failure. To efficiently control or regulate, read and write these data, a storage controller is mandatory. Thanks to our collection of high-efficient storage controllers, your storage array is in good hands.
Data redundancy is a system design to facilitate the duplication of a component, so if it crashes, there will be an alternative. There are various RAID levels, but not all have the purpose of implementing redundancy. RAID operates by storing data on multiple disks and enabling input/output (I/O) operations to overlap stably. Multiple disks increase the mean time between failures (MTBF); hence, storing data in arrays also increases fault tolerance.
RAID CONTROLLER
As the name suggests, a RAID controller controls hard disk drives in a storage array. It can serve as an abstraction level between the physical disks and the operating system (OS), assembling an array of disks as logical units. A RAID controller can either be software-based or hardware-based. In the latter, a physical controller operates the array. Depending on the manufacturer, the controller can also be engineered to support SATA and SCSI "Scuzzy" drive formats. A hardware-based RAID controller may again come as a component in the server's motherboard.
On the other hand, in the software-based RAID, the controller takes advantage of the hardware system's resources, including the memory and the central processor. It carries out the same functions as a hardware-based RAID controller. However, the software-based RAID controllers may not improve the performance of the storage system.

What is the Manufacturer/Brand Warranty?
In general, a manufacturer's warranty service/support is a written guarantee to the buyer of a product. Its terms assure the replacement or repair of the product, if necessary, within a specified period after the purchase (2-5 years depending on the brand/manufacturer). It is typically included in the price of the product. Products are brand new and sealed and the original manufacturer box is complete with the Manufacturer's genuine warranty. For most of the brand new/retail products that come with the manual and box, exceptions may apply (i.e., Cisco, Juniper Networks).
For the server parts (i.e., Dell, HPE) to get Full coverage of the warranty server must have a full 3- 5 years warranty. However, ALLHDD.COM will cover the warranty duration if any Manufacturer doesn't support the advertised warranty and there is no refund for those.
