Is your data or bandwidth being stolen? Many of us run home networks, with wireless being a popular choice. It’s so much easier to set up a decent wireless network than to deal with running cable and installing jacks in a house that’s not already wired.
How do you know your data is secure? How do you know someone isn’t nearby with an aluminum can picking up your signal, or your data? There are ways to get geeky on this subject, with spectrum analyzers and so forth. I like to keep it simple. Read the rest of this entry »

Open Your Eyes And Virtualize
Virtualization is a big buzzword right now, and for good reason. The more we virtualize, the more flexibility we build into our infrastructure. What we are really talking about is providing a layer of abstraction between our resources. The entire IT industry is moving in this direction and it’s fantastic.
Swapping server hardware has never been easier. Network traffic can be grouped and segmented without extra hardware. Storage space can move moved, increased, and even migrated to higher performance arrays without downtime. These added abstractions need to continue and I see every aspect of the data center benefitting from virtualization. Read the rest of this entry »

Deduplication has piqued the curiousity of CTOs and storage managers for a couple years, but is still in its infancy. Being able to restore a 5-year old file remotely within minutes while not having to increase fast disk (read “expensive”) storage capacity is certainly appealing.

Using deduplication technologies, companies will be able to rid themselves of tape and adhere to longer data retention policies all while saving money on the storage required to meet these needs.

RPO and RTO, what are they, and how do they relate to protecting your data? Many think RPO and RTO have an inverse relationship. That’s not necesssarily true, cost should also be a factor.
It’s important to think about RPOs and RTOs, especially when writing your SLAs or “Service Level Agreements” for customers to assure your data recovery methods will match their expectations. Why and how does RPO affect RTO and vice-versa? Is one more important than the other? Does one cost more? Can I have the best levels of both? Read on… Read the rest of this entry »

There are many security concerns for the mobile professional. Every mobile worker should be briefed on the basics of security. These concerns should be akin to keeping a wallet or purse secure, it becomes second nature for most people.
Would anyone take their private files out of their file cabinets and post them on a billboard or hand them out to others? Probably not, but many of us are doing that every day with our electronic files. The issue of mobile security can be broken down into three categories: physical security, data encryption, and wireless security. Read the rest of this entry »

VMWare’s VMFS 3 allows adding extents on the fly, and from either a separate LUN on a SAN or from extra space within a LUN that was expanded or migrated to a larger LUN. However, because it is possible doesn’t mean it should be done. There are 2 accepted ways to increase the size of a VMFS though there are at least 4 ways to do it. Read the rest of this entry »

Business does not care about virtualization. Executives do not care about VMWare, IBM, Sun, and Microsoft. The business cares about their business: maximizing profits for the short and long term.
