#CRUSH: Distributing the low-level block allocation problem

I remember when I started to work with some Block Storage Arrays – or SAN storage systems – and how vendors those days were committed to bring savings through a disk consolidation project. A solution that caused some confusion when you realized that you had to pay three times more for no so too much performance and capacity – consolidation was the trend on those days – I remember when those storage … Continue reading #CRUSH: Distributing the low-level block allocation problem

Controlled Replication Under Scalable Hashing (#CRUSH), Ceph’s Hidden Power to face any storage’s challenge

What would you think if you can customize your storage solution to the way your company really needs? It doesn’t matter how much capacity or performance you think you might need. And we are talking here about from a few TeraBytes to thousands of PetaBytes. A storage system that is able to optimally manage data from a couple of servers to thousands of them spread among several datacenters. A … Continue reading Controlled Replication Under Scalable Hashing (#CRUSH), Ceph’s Hidden Power to face any storage’s challenge

#OpenStack speeds Loosely Coupled Scale-Out storage Type’s adoption

In my previous notes I’ve shown the definition of Loosely Coupled Scale-Out Storage Architecture and I’ve mentioned some products and vendors as reference. #Ceph, the open source project, and its block storage presentation, is an example of this type of solutions. I’ve exposed as well how #Ceph integrates itself to #Openstack as a block and object storage system, and I have to say that I personally prefer … Continue reading #OpenStack speeds Loosely Coupled Scale-Out storage Type’s adoption

#Ceph versus Distributed Share Nothing Storage Architectures

Last #EMCWorld we’ve got cool key notes showing beautiful trends on storage technologies. There were frequent recalls on these two types of Storage architectures: Distributed Share Nothing: This type of architectures works on independent controllers no sharing memory resources between nodes.  This sort of solution has beed made for Non-transactional data and brings distributed data protection features. Object Storage is a solution that fits with this … Continue reading #Ceph versus Distributed Share Nothing Storage Architectures

#Ceph: The most affordable flash storage to speed your Cloud (our labs results with #OpenStack)

I want to share with you some results of our work with #Ceph with #OpenStack Cinder. We are working with three servers with SSD drives, and also Flash Cards as our journal and cache. We’ve executed three write tests with different sizes (1024MB, 2048MB and 4096MB) to Ceph devices from a virtual machine provisioned on KVM through OpenStack – the disk was provisioned through Cinder – using … Continue reading #Ceph: The most affordable flash storage to speed your Cloud (our labs results with #OpenStack)

#OpenStack likes #Ceph: You will love the way it works

Ceph scales out, Ceph is highly redundant, Ceph is flexible, Ceph is full of cool features. Ceph and #OpenStack are close friends. Te queremos Ceph! Firefly is the last Ceph’s release and is a beauty starting point for us to develop what we named “the first storage solution fully supported by KIO”. As I’ve mentioned in my previous notes regarding to this “Software Defined Storage” current reality, commodity is helping out … Continue reading #OpenStack likes #Ceph: You will love the way it works

#EMCWorld14: Totally Simple HyperVisor-Converged Cloud Experience with VMWare Virtual SAN

EMC is changing the way to eat storage through ScaleIO as It has been exposed in my last note.  There are also companies like Nutanix that has been shaken the market with this new trend of Full Cloud Converged Stack for a while. However,  VMWare has started to show out its Virtual SAN since the last VMWorld as its response to this so mentioned Software Define Storage (SDS) … Continue reading #EMCWorld14: Totally Simple HyperVisor-Converged Cloud Experience with VMWare Virtual SAN

#EMCWorld14: ScaleIO or ViPR Block – A brutal paradigm change to innovation

I am very excited to see how ScaleIO or also known as ViPR Block will be developing from now on. I had the opportunity to touch and test it at EMC vLabs and get closer to its architecture and the way how to manage storage resources. I was nicely impressed by its capabilities. I’ve posted a note 6 months ago stating that we could be facing … Continue reading #EMCWorld14: ScaleIO or ViPR Block – A brutal paradigm change to innovation

#EMCWorld14: Redefine our business, but let’s keep the traditional stuff for a while

Joe Tucci have told that EMC will support you to reach what we can say the third platform generation (mobile, cloud, big data…). But also, there will be the traditional applications like Oracle, SAP, IBM, Java… – don’t kill the messenger, he has showed their logos pretty clear in his slide as the traditional stuff – (What a nice stage, EMC knows how to impress … Continue reading #EMCWorld14: Redefine our business, but let’s keep the traditional stuff for a while

Getting backup jobs done are not a warranty you are fully protected

Would you go home to sleep confident without knowing that your data is backed up? Would you go home to sleep confident without knowing that your data is fully restorable? You wouldn’t, because you can’t know if your data will be fully restored until you have already tested it. You might have an evidence of your backup, but this is not warranty you can already restore it 100% to the most updated version. Evidence of … Continue reading Getting backup jobs done are not a warranty you are fully protected
