What is Software-Defined Storage?
Software-defined storage (SDS) is a technology used in data storage management that intentionally divides the duties accountable for
- provisioning capacity,
- protecting data
- controlling data placement
from the physical hardware where the actual data is stored.
As a result, SDS allows the storage hardware to be replaced, updated, and extended without removing regular operational procedures or abandoning other valuable software investments.
Basically, by separating software from hardware, you can gain efficiencies on both sides. For example, reducing expenses by using industry-standard servers instead of more expensive proprietary storage.
Gartner’s prediction is very often quoted in the industry, and it states that by 2024:
- 50% of the global storage capacity will be SDS
- by 2025, 85% of international companies will run containers in production
When SDS is used together with cost-effective and highly performant storage (SSD or NVMe), it starts to show that the technology it’s arriving at a new point in its development.
Such combination uses the benefits which were once available only to hardware-based storage arrays – with the potential of low latency, which was available only in hyper-converged infrastructure. When used with Kubernetes, such a combination promotes a developer-friendly, declarative, and agile environment open to auto-scaling.
Benefits of SDS
1. Decrease data fragmentation
Data silos limit visibility and add resistance to a broad range of applications – from data analytics to the compliance of regulators. When an SDS platform supports several storage protocols – such as block, file, and object, you can incorporate all the silos in a single infrastructure. In addition to a robust API, which can allow orchestration and automation, such a fortified SDS platform can facilitate storage management while significantly increase its total cost-efficiency.
2. High availability and disaster recovery
When data is easily stored and managed across different environments, businesses can reduce the economic shock of possible hardware failure. This includes failures of not just a single disk or node but also an entire site.
When SDS is used, data can be saved on several locations simultaneously, which removes the need to move data in the event of a disaster physically.
This makes it easy to guarantee multi-site high availability for apps on data centers separated on different geographic locations. Businesses also don’t need to deploy many complicated and expensive replication technologies on top of their storage infrastructure to ensure business continuity and disaster recovery SLAs. And such decisions naturally improve uptime while significantly reduce expenditures.
3. Provisioning of storage
According to its specific needs, IT has the freedom to choose the proper environment for each application. In such scenarios, IT can be more flexible to store and manage data across various assets.
This granular approach lets storage admins bypass the difficulties and issues of one-size-fits-all storage and support business SLAs while reducing the overall expenditures.
4. Improve scalability
Scaling with software-defined storage can be done quickly with regular commodity servers. This omits the need to pay for things you don’t use, and you can increase your capabilities only when you need them. In such a case, overprovisioning becomes a thing of the past. This also includes the wasted money that naturally comes with it.
But what it brings is that it allows storage admins to answer fast to their organizations’ needs. IT can help the business be more efficient, competitive, and adaptable in such a manner.
The influence of the lockdown on online business, shopping, and entertainment
Even though mass vaccination is underway in most of the world, it seems evident that until the end of 2021, lockdowns and restrictions will continue.
Many online businesses have felt the result of these restrictions. For example, more people in their homes have put an unprecedented need for online entertainment. Video streaming and online gaming have all experienced a rapid increase. For example, a study has estimated that the average screen time for adults in the UK has increased by 31% – a third than in 2019. Other studies have found a 100% increase in online gaming or 198% in OTT traffic.
There is a dramatic change in customer behavior at the moment. E-commerce is under tremendous strain to perform – with online shopping experiencing rapid spikes, while many smaller businesses are filing for bankruptcies in the US.
These new trends also follow the massive trend of work-from-home shift, where even big companies are sending their employees to work remotely.
The use cases for SDS usually include:
- Remote offices
- Ruggedized systems
- Hybrid cloud implementations
- Datacenter infrastructure modernization.
When organizations need to answer wide fluctuations in the environment, budgets are under strain, SDS can be almost certainly the best possible solution.
Implementing Software-defined storage allows companies to reduce their expenses without sacrificing performance significantly. And it can also help their availability and disaster recovery.
