Open Storage Concept - Open Storage Systems
What is open storage?
Open architecture
Industry standards for hardware and open source software with integrated storage functionality (higher scalability and lower cost of ownership compared to proprietary systems)
Open source software
Open source and API (third-party software support)
Interoperability
Simple and predictable integration of systems into a heterogeneous environment (open standards)
Management Software Features
Online monitoring of the entire storage system
- Built-in DTrace Tools
- NFSv3, NFSv4, CIFS, iSCSI
- ZFS and Solaris i / o path
- CPU and Memory Utilization
- Networking (TCP, UDP, IP)
- Online Graphic Analytics
- Maximally Used Files
- Read / write resource allocation
- Storage utilization from CIFS clients
- IP Interface Bandwidth
- Ability to export data for subsequent compression
- GUI for ZFS file system
- Easy to manage and configure
- Ability to manage through CLI
Solid State Drives (SSD)
Components of SSD:
A) Controller
B) DRAM
C) FLASH bank
Each FLASH chip is part of a common virtual pool and its space is addressed by the built-in controller.
The controller monitors:
- Wear leveling
- CRC
- Bad block mapping
The controller provides support for interfaces such as SATA, PATA, SAS or FC
