SSDs Are Not Confusing
Seems like every vendor I speak with is laying out its solid-state disk (SSD) strategy, and almost all say they're trying to help the customer through this confusing platform change. It's not confusing.
IBM Fined $900,000 For Failing To Backup
The Dallas Morning News reported that the state of Texas is fining IBM $900,000 for failing to make timely backups as part of an $863 million outsourcing contract. Gov. Rick Perry also suspended the transfer of additional state records into the IBM system, claiming the new system puts state agency data at risk.
Green Storage Is More Than Just Green Drives
Most, if not all, the hard drive manufacturers have come out with green drives; drives that spin down or turn off. There are two problems with counting on green drives to reduce your power consumption; first, they are only one component in the storage solution, and second, there has to be intelligence for them to be used optimally.
Are 'Green' Drives Really Green?
The storage industry is often guilty of jumping on the bandwagon without giving the architecture much thought. We see this in solid state disk, data deduplication, and green drives. Are users really going to see decreased power consumption by deploying green drives? If so, is it going to be worth the effort of replacing your current systems?
NAS Clusters, How Should You Couple?
A split decision surrounds the use of tightly coupled or loosely coupled solutions. There aren't enough implemented cases yet available to make a determination on the best approach; the deployments that have been made aren't stretching either method to the point a real determination can be made.
Clustered NAS In The Cloud
It seems that nowhere is the use of clustered NAS going to be more prevalent than in the cloud. They seem tailor made for each other because cloud-based services have the need for massive scaling and moderate performance while being very cost effective. Clustered NAS solutions seem to fill that bill.
Clustered NAS, Part One
It seems as though every manufacturer is now offering clustered NAS. There are so many variants that I can't cover everything about them in one entry, but basically each solution tends to focus on a particular capability; some are built for scale, others are built for performance, and, of course, there are solutions that try to deliver a happy medium. Over the next several entries we will do some exploration of these systems and where they might make sense for you.
Primary storage needs a break from the capacity optimization drumbeat ... at least mine. Let's focus on one of the other top subjects at SNW: network-attached storage (NAS). It's certainly not a new technology, but NAS has remained near the top of everyone's mind and now with the growing interest in NFS and VMware, there's additional wind in the sails of NAS adoption.
Primary Storage Under Siege
It seemed like Storage Networking World was all set to make solid-state disks the big theme at this year's event, and then the economy went in the tank. Primary storage suddenly became an evil, expensive power-hungry monster that needed to be eradicated. To the rescue came solutions that would compress, dedupe, thin, and migrate this villain down to size.
Saving Storage Dollars -- Manual Moves
With the current financial news, IT professionals are looking for ways to keep budgets flat. There is a common misconception in storage that there is only so much you can do. Over the next several entries, we'll explore a host of options that you can implement to curb storage costs. Today, it's manual moves.
Targeting Primary Storage
Primary storage is the next target of optimization. As mentioned in my last entry, the growth rate of active data on this storage is small, what is growing is the older data set which, for now, still remains on primary storage. Optimizing primary storage is the most significant step you can make in reducing not only your storage budget but also your storage's use of power and cooling.
Your Data Is Not Growing
Well, your active data isn't growing, or at least it isn't growing very fast. What is growing is the amount of data that you now hold on to. If you could eliminate that data, your ongoing investment in primary storage would be minimal.
Replications On A Theme - Host-Based Replication
Disaster recovery is certainly more than getting the data out of your data center and having it land in a remote facility, but that isn't a bad pace to start. Problem is, there are now 800 different ways to replicate data.
HP Acquires LeftHand Networks For $360 million
LeftHand Networks was one of the first vendors in the iSCSI market and has always had the best of the iSCSI solutions that runs on standard x86 server hardware. It has transitioned over the past couple of years from selling whitebox servers with its SAN/iQ software bundled in to primarily selling SAN/iQ as software, upping the ante this February by releasing SAN/iQ as a VMware virtual appliance.
