Scale-Out Storage: The Advantages of Replication vs. Erasure Coding

Scale-out storage systems tend to protect data from media failure in one of two ways; they either use replication or erasure coding. Replication creates a user-defined number of copies of data, typically a minimum of three, as it is created

How Object Storage Makes a Hybrid Array Better

In our last blog, Storage Switzerland discussed how a hybrid array, with a properly sized flash tier, could provide similar performance to an all-flash array while substantially reducing costs. The next step in storage architecture design is to use the

Hyperconvergence is NOT Backup

One of the riskiest claims a vendor ever makes is “we’ve eliminated the need for backup” and hyperconverged infrastructure (HCI) vendors make this claim frequently. Good data resiliency is not good backup, and in fact, some of the work that

Enterprises, You Want Object Storage But Not For Objects

The industry has been espousing the merits of object storage for years now and cloud providers have been quick to adopt the technology. The enterprise, on the other hand, is more cautious, partly because the object storage alternative, Network Attached

An Alternative Approach to HCI

Hyperconverged Infrastructures claim to be a simpler alternative to a traditional architecture with a dedicated compute and a dedicated storage tier. The primary source of the simplification is the elimination of a dedicated storage tier. Instead, HCI integrates storage into

“Just Adding Another Node” – The Hidden HCI Scale Complexity

Hyperconverged Infrastructure (HCI) is supposed to make scaling easier. When the architecture needs to deliver more compute power, storage performance or storage capacity, just add another node. The problem is “just adding another node”, especially as the number of nodes
