How Deduplication and Compression Make All-Flash Storage Affordable

 


Jealous of the pure power of all-flash but concerned about cost?
The latest generation of all-flash arrays have a couple of tricks up their sleeve that make the difference in usable capacity and cost between flash and spinning disk much less significant: inline deduplication and compression.

Have You Outgrown Your Symantec NetBackup Domain?

How do you know if your NetBackup Domain has become too large? 

When NetBackup Domains grow beyond Symantec best practices guidelines, performance and manageability can begin to degrade. During my 15 years as a NetBackup backup engineer, I’ve found that the following 5 criteria are worth considering:

Catalog size - As the catalog grows, the time required to protect it can become excessive. The catalog backup is a database backup. The synchronization checkpoints and locking required for other NetBackup jobs will cause extra processing time.

Cisco’s UCS Firmware Management: Why All the Excitement?

Firmware Management – The Evil Mistress

Firmware management is not traditionally a topic that anyone gets excited about. In fact, it’s typically relegated to the bottom of the IT team’s list of priorities because it’s often painful and time consuming.

From a management perspective, budget spent on firmware management is very difficult to justify and ROI is nearly impossible to measure. But firmware is an evil mistress - if it’s not attended to often enough - out of date firmware can stall an OS upgrade, prevent the introduction of new hardware or worse, cause an unexpected outage of critical equipment in the data center.

We all have stories of servers, switches, storage arrays, etc. that ran fine for years until one day, the system crashed for no reason. We later discovered that there was a critical bug fix quietly released two revisions of firmware prior to the one we were running. Grrrr!

The addition of Storage Lifecycle Policies (SLP’s) in Symantec NetBackup 7.6 has provided backup administrators with a very effective tool for managing backup/snapshot, image, duplication, and replication.

While SLP’s simplify these tasks, careful consideration is required when you’re monitoring and managing the policies and the components utilized in your NetBackup environment.

The SLP administration window we all know and love, shown below, is a great tool for managing SLP’s. But there are other things you should consider to help manage your SLP’s.

Hypervisor-Based RecoverPoint: A New Twist for Backing Up VM’s

It happens all the time – a customer has a problem that’s tough to solve. I was recently asked how to best protect a virtual environment – stretched between two data centers. The customer wanted all administration through vCenter with instant recovery and the ability to meet stringent RPOs and RTOs. And the catch – they wanted the backed up data to be stored on a different vendor’s array utilizing a different protocol - NFS instead of Fibre Channel (FC) block storage.

Moving Your Data to the Cloud? - 5 Tips to Ensure It’s Safe and Secure

Is that light you see at the end of the proverbial tunnel, or is it the headlight of an oncoming train?

The future of your professional career just might depend on your ability to successfully lead your company to the cloud. So many things to consider…


Yes, the cloud offers many advantages to your business including agility and high levels of fault tolerance, but in and of itself, the cloud does not release you from backing up your data in order to protect yourself from user error, data corruption, or data loss.


Just like provisioning new applications or scaling current applications, you need to consider every angle when protecting your data that lives in cloud.

Hybrid Cloud Management: Unraveling vRealize

 
As VMware is wont to do, it has released a new brand of products that users may already be familiar with. Though I witnessed a number of complaints from users during the small group discussions at VMWorld, the vRealize rebranding really does go beyond simple marketing. Until a couple of days ago, the products that now make up the vRealize Suite came from very different origins, and had been positioned for very different use cases, from simple monitoring to justifying ROI. However, these products were also unique in how they integrate with VMware’s cloud offerings, thus the logic behind the mirrored vRealize Air product line.
 
vRealize is a culmination of VMware’s strategy to transition their products to the cloud and to show that they continue to deliver value once the user has made that transition.

4 Cloud Strategies to Secure your Corporate Data

 
By now, many of you are probably aware of the most recent cloud breach where a large cache of celebrity nude photos was released on a forum board on 4chan. Though details are still emerging, the prevalent theory is that the hackers managed to gain access to the pictures by accessing the celebrity’s Apple iCloud accounts.
 
This is but the most recent security breach in a long string of security breaches, affecting major enterprises like; Sony, Twitter, Target, and even the Department of Homeland Security. It’s not your company data necessarily that these data thieves are interested in. Rather, it’s your contact data – the personal data you compile on each contact in your data base such as social security number, credit card number, and email address. This naturally raises the question; just how secure is your corporate data in the cloud? The hard truth is - “it depends”. Fact is, the only surefire way to guarantee your cloud data is 100% secure is to disconnect it from the cloud.

As he does on every show, Monty points to two doors. They look identical. You can't see what's behind the doors, but the payoff is potentially great. He says, "Your transition to the cloud sits behind either door #1 or door #2. Which door do you choose?
