What is hybrid raid editing

Hybrid raid is a redundant storage solution that uses high-capacity, low-cost SATA or high-performance SAS drives with low-latency, high-iops SSDs, plus SSD-aware raid control cards.

Hybrid RAID Deployment

In hybrid raid, read operations take place in higher-speed SSDs, while for redundancy, write operations are performed on SSDs and HDDs. Hybrid RAID is suitable for applications with lower data levels, such as Internet gateways, file servers, or virtual machines.

1. Advantages of hybrid raid

The performance of a hybrid RAID array is far more than a standard HDD RAID array and is less expensive than a pure SSD RAID array.

Compared to pure HDD raid arrays, hybrid arrays accelerate iops and reduce latency, enabling data centers and cloud environments to host more users, execute more transactions per second on each server, and reduce the number of servers required to support any specific workload.

In addition to reducing the number of servers in the data center server footprint, the financial benefits are reduced the capital expenditure required to procure additional servers, as well as operational expenses related to power, cooling and maintenance.

2. Hybrid RAID Solution

From a hardware perspective, building a hybrid RAID solution can use any capacity SSD and HDD (though the number of SSDs and HDDs must be the same). If the RAID array uses a different drive size, the drive capacity is the smaller one. For example, a RAID 1 With 1 128GB SSDs and 2TB HDDs, the logical device is 128GB. A RAID 10 uses 2 128GB SSDs and 2 2TB HDDs, and the logical device is 256GB. The remaining HDD capacity is available for storage.

From an application perspective, because most software does not recognize the possibility of using two different characteristics of storage. To take advantage of hybrid raid, you must deploy a RAID control card with intelligent storage processing power and SSD awareness.

With the latest firmware upgrades, the Adaptec 6 series, 5Z series, 5 Series, 2 series, and Q Series control cards make good use of the remaining capacity, automatically create a hybrid RAID array, and make 1 or more SSDs with the same number of HDDs as RAID 1 or RAID 10 arrays.

This hybrid RAID array is transparent to the operating system and all running applications. In addition, the Adaptec control card provides the highest mixed array performance by writing to HDD and SSD, 100% from SSD.

Adaptec Hybrid RAID arrays provide higher IOPS performance than standard HDD arrays, while write I/O performance is not degraded.

Some applications even see a small amount of performance benefits from Adaptec hybrid raid, and the hybrid RAID 1 speed is faster than a single SSD.

From the above description, I think we all have a lot of knowledge of mixed raid editing. If our RAID data is accidentally deleted, we have to go to a specialized agency to recover the data. Shanghai Day Shield Data Recovery Center is a good choice, I believe their professional ability can help us recover the lost data in raid.
