Data storage systems for IT infrastructure and data centers

Storage for databases, virtualization, backup, archiving, and media content – ​​based on SAN, NAS, object storage, and JBOD solutions.

We'll build a storage system for your applications: from high-performance arrays to scalable archives.We take into account supply and service support restrictions in Russia.

What types of data storage systems are there?

SAN (block storage)

Provides servers with logical disks (LUNs) that they access as local disks, via iSCSI, Fibre Channel, or NVMe-over-Fabric.

For high-performance tasks: databases, virtualization clusters.

NAS (file storage)

Provides access to data via NFS/SMB file protocols as shared network folders.

A resource for offices, project teams, VDI, and unstructured file storage.

Object Storage (S3)

Stores data as objects with metadata and scales horizontally.

For backups, archives, analytical data lakes, and cloud services.

JBOD and disk shelves

Disk sets that attach to servers to create your own scalable systems.

High-density solutions and software-defined systems (SDS).

Where are data storage systems used?

Virtualization and databases

Low latency, high IOPS, and predictable response times for virtual machines and DBMS are critical.

All-flash arrays designed to meet the needs of specific hypervisors.

File storage for offices

Secure access to NFS/SMB shares for document and media collaboration.

For project teams from tens to hundreds of employees.

Backup and Archives

The main focus is capacity, reliability and cost of long-term storage.

Combinations of NAS, object storage and deep storage tiers.

Video surveillance and media content

Stable sequential recording and the ability to expand capacity without interrupting services.

Scalable NAS solutions for large video arrays.

Key parameters when choosing a storage system

Before choosing an array or storage platform, it's a good idea to review the following parameters to avoid common mistakes and budget overruns.

Free consultation

We will help you select a configuration based on your actual loads.

Contact an engineer
1

Load and access profile

Is random or sequential access predominant, what are the IOPS requirements?

2

Current capacity and growth (3-5 years)

Account for projected growth to avoid rapid overcrowding.

3

Performance

IOPS, throughput and latency for mission-critical systems.

4

Types of media

Combination of SSD/NVMe for hot and HDD for warm and cold data.

5

Fault tolerance

RAID, replication, clusters and data protection.

6

Scalability

Compatibility with hypervisors, OS and applications.

7

Budget and TCO

Accounting for licenses, services, extensions, and energy consumption.

Typical approaches to building a warehouse

SAN array for virtualization

Block storage with Fibre Channel or iSCSI connectivity.

TargetClusters of tens to hundreds of virtual machines and highly loaded DBMS.
PlusCombination of SSD/NVMe for hot data and HDD for cold data.

Scalable NAS

File storage with NFS/SMB access for shared folders.

TargetOffice resources, project teams and video surveillance systems.
PlusIncrease capacity and performance as your data grows.

Object Storage (S3)

A solution that scales horizontally as volumes grow.

TargetBackup and long-term storage of archives.
PlusControlled and predictable cost per terabyte.

High-density JBOD solution

Disk shelves with a large number of HDDs connected to servers.

TargetCustom software-defined storage (SDS) and low-cost archives.
PlusThe key parameter is the minimum cost per terabyte.

Common mistakes when choosing

Ошибка 1: Недооценка роста объёмов

Storage is quickly filling up, forcing us to urgently expand the system and go beyond our budget.

Ошибка 2: Выбор только по ёмкости

Ignoring performance leads to a drop in IOPS and an increase in latency for the DBMS.

Ошибка 3: Отсутствие стратегии защиты

Without a backup and replication scheme, the risks of downtime and catastrophic data loss increase.

Ошибка 4: Привязка к одному вендору

Closed platforms complicate upgrades, migrations, and licensing negotiations.

What systems do we work with?

We use solutions from leading SAN, NAS, and object array manufacturers. Specific brands are selected for each specific task.

SAN arrays

for databases and virtualization

NAS systems

for files and media

Object storage systems

for backups and archives

JBOD platforms

for custom solutions

How we help with storage projects

We help you assess your current workload, design your target architecture (SAN, NAS, object, or hybrid), and select configurations that fit your budget.

If you already have a technical specification or a current configuration, send it to us – we will offer options for modernization and optimization.
