Advantages of a NAS Box over External Hard-disk drive for Storage/Backup in SOHO/SMB

For a small business / SOHO there may be relatively few documents and files to store, but the available budget and the technical expertise is limited. In such cases, why not consider a NAS (Network Attached Storage) Box instead of External Hard-disk Drive for storage / back-up? An entry level NAS box might give many features and functionalities that may be very useful for SOHO / small business users and the price difference between an external hard disk & entry level NAS box is not very much.

RAID Basics & RAID Recovery

RAID Basics: RAID Systems (In Computers, Servers, NAS, etc) use multiple disk-drives to store data to prevent data loss when individual drives fail & to increase the read/write memory performance. Software based RAID systems provided by the operating systems use the system CPU to create and manage RAID drives while…

What is a Converged Network Adapter (CNA)?

In large enterprise companies, main servers have (at least) two adapters – FC HBA (FIber Channel Host Bus Adapter) & Ethernet NIC (Ethernet Network Interface Card) to connect to the storage network (Fiber Channel) and computer network (Ethernet). Converged Network Adapters converge the functionality of both the adapters into one. Read on, to find out more…

Why you need to implement a Storage Area Network using iSCSI over an IP Network

The first image defines what is iSCSI and what exactly its role is, in Storage Area Networks. Convergence is happening over IP everywhere (one reason why IP is exciting!), and even the Storage Area Network is expected to converge over IP networks through iSCSI especially with the anticipation of lossless Converged Enhanced Ethernet. The other popular option being FCOE (Fiber Channel Over Ethernet).

Storage/Network Convergence with FCOE: Fiber Channel Over Ethernet – Need, Advantages & Limitations

FCOE or Fiber Channel Over Ethernet transports the SCSI storage data (used in FC networks) using Fiber Channel Protocol stack instead of TCP/IP stack; using the Ethernet infrastructure (NIC, Cables, Switches, etc). FCOE maps the FC commands and data directly into Ethernet frames (Fiber Channel frames are encapsulated in an Ethernet frame to create FCOE and the mapping is 1:1 meaning, there is no segmentation or compression of FC frames.

Are we moving towards Solid State Disks/Drives for Storage?

With Apple’s MacBook Air standardizing on flash based storage system for their ultra-portable laptop, can we see this trend picking up with enterprise storage as well? Why is the industry excited about the Solid State Storage? Is the Solid State technology trouble-free and mature enough? What are the types of flash based storage and what capacities do they come in today? These are some questions well be answering in this article.
