Infrastructure Software Defined and VM-Aware Storage
SOFTWARE DEFINED STORAGE (SDS)
Storage infrastructure that is managed and automated by intelligent software as opposed to by the storage hardware itself. In this way, the pooled storage infrastructure resources in a software-defined storage (SDS) environment can be automatically and efficiently allocated to match the application needs of an enterprise.
Separating the Storage Hardware from the Software
By separating the storage hardware from the software that manages the storage infrastructure, software-defined storage enables enterprises to purchase heterogeneous storage hardware without having to worry as much about issues such as interoperability, under- or over-utilization of specific storage resources, and manual oversight of storage resources.
The software that enables a software-defined storage environment can provide functionality such as deduplication, replication, thin provisioning, snapshots and other backup and restore capabilities across a wide range of server hardware components. The key benefits of software-defined storage over traditional storage are increased flexibility, automated management and cost efficiency.

NexentaStor delivers unified file (NFS and SMB) and block (FC and iSCSI) storage services, runs on industry standard hardware, scales from tens of terabytes to petabyte configurations, and includes all data management functionality by default. NexentaStor is Open Source-driven Software-Defined Storage with SMARTS: Security, Manageability, Availability, Reliability, (lower) TCO, and Scalability.
VIRTUALISED SAN (VSAN)
VMware Virtual SAN is radically simple, hypervisor-converged storage designed and optimized for vSphere virtual infrastructure. DiGiCOR Solutions integrated with VMware Virtual SAN.
DiGiCOR’s Virtual SAN (VSAN) Ready Nodes focus on deploying VMware® Virtual SAN™, a hypervisor converged solution, as quickly as possible. Virtual SAN provides you with the ability to provision and manage compute, network and storage resources from a single pane of management. Working with VMware, DiGiCOR delivers an alternative to traditional Fiber Channel SAN based virtualization infrastructure, which is known for its complexity and interoperability challenges. Targeted at a multitude of use cases in tier 1/2 production workloads and Virtualized Desktop Infrastructure (VDI), especially with all flash VSAN 6.0, DiGiCOR’s VSAN Ready Nodes introduce a new high performance storage tier optimized for enterprise-class virtual environments that is simple, resilient and efficient that reduces the total cost of ownership. It is a perfect solution for Enterprises ROBO and SMBs to efficiently grow and manage virtualized infrastructure for maximum ROI.
A Virtual SAN Ready Node is a preconfigured single-node or multi-node server hardware configuration for use with Virtual SAN. A Ready Node configuration includes specific type and amount of CPU, Memory, Flash, HDD, and IO Controller devices within each server. Each VSAN Ready Node is classified by a Ready Node configuration profile. Defined Ready Node profiles include:
- Server workload profiles (Large/High server profile, Medium server profile & Small server profile)
- VDI workload Profiles (VDI with Linked Clones & VDI with Full Clones)
Each configuration profile provides a differentiated price/performance focus, targeting multiple use case requirements. Each profile assumes a target number of Virtual Machines per node, utilizing an average Virtual Machine profile size. Fault tolerance is built into the solution with data replication between nodes, and clustering technology. Flash and hard disks are seamlessly integrated to achieve best balance in performance and capacity.
VM-AWARE STORAGE (TINTRI)
The Tintri VMstore T800 Hybrid-Flash series aligns your storage with your business needs—putting the focus on your virtualized applications. Tintri’s VM-Aware storage speeds performance 6x to save you time, and packs storage 10x more densely to save you money. The T800 Hybrid-Flash series is ideally suited to your multiple workloads and hypervisors, large (and growing) VDI deployment, and/or your private cloud. Take every storage action at the VM-level—manage, replicate, automate and analyse any (or every) VM to keep storage simple. Tintri’s all-flash and hybrid-flash arrays share a common OS and analytics so you can balance workloads and manage your entire footprint from a single pane of glass.

ADAPTIVE FLASH PLATFORM (NIMBLE)
Nimble Storage CS-Series arrays are the building blocks of Adaptive Flash, a storage platform that dynamically and intelligently allocates storage resources to satisfy the changing needs of business-critical applications. Adaptive Flash is based on CASL™, Nimble’s patented Cache Accelerated Sequential Layout architecture, and InfoSight™, its data sciences-based approach to the storage lifecycle. CASL allows performance and capacity to be scaled seamlessly and independently. InfoSight leverages the power of deep-data analytics to deploy storage resources as needed by business-critical applications.
OBJECT BASED STORAGE CLUSTER (CEPH)
With the advancement of large scale cloud computing platforms like OpenStack, the business of data storage has been forever changed. Often called “the serverisation of storage”; the replacement of purpose-built/proprietary data silos with economical server hardware, has proven itself to be both more reliable and more resilient. Ceph is an open-source, massively scalable, software-defined storage platform delivering unified object and block storage making it ideal for cloud scale environments like OpenStack. DiGiCOR Ceph storage solutions are available as fully qualified bare metal server hardware reference architecture ready for user deployment of open source Ceph.
Organizations prefer object-based storage when deploying large-scale storage systems because it stores data more efficiently. Object-based storage systems separate the object namespace from the underlying storage hardware. This simplifies data migration.
THE CEPH STORAGE DIFFERENCE
Ceph’s CRUSH algorithm liberates storage clusters from the scalability and performance limitations imposed by centralized data table mapping. It replicates and re-balances data within the cluster dynamically— eliminating this tedious task for administrators while delivering high performance and infinite scalability.
