Data Storage

Data storage is the collection and retention of digital information using computers and other devices. The information is kept in a digital format to be retrieved and accessed later by users and applications. The methods and technologies used for data storage vary greatly, but the basic concept is always the same: information is kept so that it can be accessed again later.

Managing data storage grows more difficult year-over-year. Organizations from small businesses, mid-size enterprises, to large corporations are more reliant on their data than ever. Performance-hungry applications and the rapid progress and the growing need to store data are making it more costly and increasingly demanding to ensure data is available when needed. Businesses need powerful yet cost-efficient solutions that can help streamline data management, reduce latency, enable stronger data protection, and make data continuously available.

Data storage today is more diverse than ever and resides in many locations, thanks to evolving technologies like hybrid cloud, multi cloud and public cloud, software as a service (SaaS), disaster recovery as a service (DRaaS), in addition to traditional on-premises compute, applications, databases and storage requirements. The challenges for managing data today include:

Managing Growth – As data demands grow, the cost and complexity of storing, managing, and protecting it increases as well.

Containing Costs – IT budgets can hardly keep pace with the growing complexity and data storage demands.

Protecting Data Resources – Data is a very valuable asset and is constantly under attack and must be protected from loss, theft, and corruption. Data must be backed up at geo-redundant locations.

Simplifying Management – Managing data storage can easily overwhelm IT teams that are also working on other priorities.

Reducing Latency – Evolving technologies need real-time access to data, requiring data storage solutions with minimal latency.

Providing Easy Access – Developers, IT operations, security, compliance, and a wide variety of users all need access to data quickly and easily.

Compliance – Increasing volumes of data make it hard to determine whether data follows policies, regulations, and laws.

Nfina-Store Data Storage Solution

Nfina-Store provides unlimited options to architect storage environments with iSCSI, Fibre Channel (FC) and NFS, SMB (CIFS) protocols for companies of any size – from small businesses, mid-size enterprises to large enterprises. The Linux-based architecture provides Nfina-Store with much better hardware compatibility than competing products based on other operating systems. Nfina-Store is a perfect choice for any virtualized storage environment as it supports VMware, Citrix, Microsoft Hyper-V and ProxMox. It can be set up on physical servers or as a virtual storage appliance (e.g. in hyper-converged environments).

Data Acceleration

  • Acceleration of random writes with Write Log (ZIL) See illustration below
      1.  Writes are written to ARC first
      2. Writes are copied to ZIL
      3. After data is written from ARC to the Storage Pool, ZIL data blocks are freed
  • Hybrid Read Cache with first level in RAM (ARC -Adaptive Replacement Cache) and second Read Cache level on an SSD or NVMe (L2ARC) See illustration below
      1.  Attempt to read requested block from ARC
      2. If block is not in ARC then read from L2ARC to ARC
      3. If block is not in L2ARC then read from Storage Pool to ARC
ARC-Pyramid Graphic
  • High cache hit rate by using ARC’s most recently used (MRU) and most frequently used (MFU) Read Cache algorithms. See illustration below
