Nexsan Answers the Call for High Density Apple Xserve and Mac Storage

Lately I’ve been contacting RADirect customers that I know work in Mac environments to introduce them to Nexsan’s newly launched (read press announcement) SATABeast Xi SATA array – designed specifically for Apple Xserve and Mac Pro systems.

Like the standard SATABeast SATA array, the Xi version has all the enterprise-class features you’d expect, at an extremely low price (as low as $1,250 per TB):

• High density, with up to 42 TB in only 4U
• Greener – extreme energy efficiency saves on operating costs
• Flexible, scalable, and completely OS independent
• Single or dual RAID controllers
• Redundant, hot swappable components

And it's been modified for use in Apple environments:

• Look and feel - the SATABeast Xi’s form factor and GUI interface have been redesigned to be more familiar and comfortable to Apple / Mac users.
• Looks great in Safari / Leopard interfaces.
• Ideal for data intensive multimedia applications like uncompressed real-time HDTV and high quality video editing.
• Also compatible with non-Apple servers and workstations, so it's perfect for mixed OS environments.
• No premium pricing – the SATABeast Xi is available at the same price point as the standard SATABeast.

For more details, you can download the complete SATABeast and SATABeast Xi SATA array data sheets from RADirect’s web site – start here.

If you’ve already deployed the SATABeast Xi, I’d love to hear from you.

A Few Thoughts for the CIO: This is the Year...

In just a few weeks we’ll ring in 2008 with the usual fanfare. But what’s not usual about this coming year is the state of uncertainty it brings along with it. With market volatility and the fear of a recession offering more questions than answers, we’re all a lot more cautious when it comes to spending money.

Of course, the logical reaction to such market uncertainty is to hold off on new projects and expenditures. My wife and I recently decided to postpone a new car purchase for this very reason.

But there’s no getting around the fact that some purchases, those most critical to the continuation of your business, simply can’t be put off.

If you need it, you need it.

But this year, more than ever, is the time to be extra diligent in evaluating your options.

This is the Year...
To scrap the old mantra: ‘No one ever got fired for buying [insert major brand name]’. Because although [insert major brand name] may have a strong reputation for reliability, chances are the associated outlay is much higher than you’re comfortable spending right now.

This is the Year...
To look for alternative solutions that will lower your overall TCO and offer a healthy balance between price, performance, and reliability.

This is the Year...
To minimize your risks by choosing a solution that’s been proven, yet still cost-effective.

At RADirect, I’m speaking with a lot of storage customers about things like consolidation and tiered storage, which fits right in with this way of thinking.

How is the current market volatility affecting your budget planning for 2008? Drop me a line - I’d love to hear from you.

RAID Storage: Green, Green, and Getting Greener

Seems like everywhere I turn lately, there’s commentary on the critical need for data centers to “go green”. In fact, internetnews.com published two articles on the topic (“Greening Your Data Center...” and “Green is Hot for Storage Managers”) in less than two weeks.

So why all the buzz? Soaring energy costs (including the cost of cooling). Environmental responsibility. Emerging regulations that govern power consumption levels. In short, companies are challenged to find more energy efficient ways to store higher volumes of data and retrieve it faster.

Analysts and experts have released all kinds of statistics and predictions that are extremely frightening, such as:

• IT organizations are now spending 25% of every hardware dollar on power (IDC)
• IT departments can expect to spend half of their total budget on energy (EPA draft report on server and data center efficiencies)
• By 2008, half of current data centers will have insufficient power and cooling capacity to meet the demands of high density equipment (Gartner)
• By 2009, energy costs will emerge as the 2nd highest operating cost in 70% of worldwide data center facilities (Gartner)

Well then, I guess it’s no surprise that energy efficient products have increased as a buying priority.

Fortunately, a few storage vendors are ahead of the game. For example, Nexsan Technologies, a veteran green machine which has installed more than 50 petabytes of “green storage” since 2001, incorporates their proprietary AutoMAID™ (Massive Array of Idle Disks) technology into their SATABeast and SATABoy SATA storage arrays.

This technology transparently places disk drives in an idle state to conserve energy yet still allows for near-instantaneous access to data, resulting in reduced power consumption and operational costs.

According to a recent Nexsan press release, the SATABeast SATA RAID array (at Level 3 AutoMAID), consumes up to 25 times less power than conventional storage arrays. If the requirement for greener storage continues to grow as I predict it will, this is the kind of stuff buyers will be looking for.

By the way, I noticed that the SATABeast was selected as a finalist for “Green Product of the Year” at this year's Techworld Awards in the UK. Nice!

Data Backup or Archiving – Which Do You Need?

(Note from Uri: Today’s post is contributed by RADirect Systems Engineer Steve Insdorf)

Over time, I’ve come to realize that the distinction between data backup and data archiving can sometimes be cloudy, with the two terms often used interchangeably. The truth is there are many important differences between the two, so I thought I would use this entry to help clarify.

Put simply, a backup is created for emergency purposes – short term recovery in case the original data is lost or damaged. In contrast, the purpose of an archive is to store, protect, share and manage data assets for the long term and make them accessible for re-use on a regular basis.

In addition:

1. Backup systems are best for dynamic data that changes regularly – for example, customer databases. Digital archives store fixed content that doesn’t change, such as email archives, medical images, financial data, legal documents, images and video, etc.

2. While a backup is simply another copy of data stored on your primary systems, an archive is a preservation of original data moved off of your primary systems.

3. A backup stores data offline. An archive stores it online or near-line.

4. With backup, you generally have a blanket retention policy for all files. True archive systems allow you to set retention policies at the file-level.

5. With backup, data volume or time of day usually determine when data is copied. On an archive, data movement is determined by policy or event.

6. An archive is easily searched and directly accessible by many users – a backup is not.

Have a backup application? I think your best bet is Nexsan’s range of RAID storage arrays. For archiving, you want their Assureon content addressable storage solution.

Are You Meeting Your HIPAA Compliance Obligations?

I recently returned from SIIM 2007 in Providence, Rhode Island - among the year’s most prominent technology events in healthcare. One of the biggest takeaways was that clearly, HIPAA compliance is of critical concern for healthcare providers, so I wanted to take a moment and add my two cents on this important and multifaceted subject.

The HIPAA Act of 1996 affects virtually all healthcare providers, health and life insurers, public health authorities, healthcare clearinghouses, and self-insured employees, just to name a few. It calls for severe civil and criminal penalties for noncompliance.

If your organization fits into the above, it’s vital that you familiarize yourself with this subject and make certain that you comply with HIPAA regulations.

HIPAA compliance calls for:

• Standardization of electronic patient information.
• Unique health identifiers for individuals, employers, health plans and healthcare providers.
• Security standards protecting the confidentiality and integrity of ‘individually identifiable health information’, past, present and future.

When implementing a HIPAA-compliant data storage system, be sure it addresses the following:

• A means to control access to electronic protected health information only to authorized personnel.
• A mechanism to encrypt and decrypt data.
• Audit control mechanisms that record and examine activity.
• Policies/procedures that will protect your data from improper alterations or destructions.
• The ability to substantiate whether a file has been tampered with, so the authenticity of information can be confirmed.

If you’re looking for a good data archiving solution to help you achieve HIPAA compliance, be sure to check out Nexsan’s Assureon.

SATA Storage with 1TB Drives

Nexsan has ‘em first! 1TB drives are now incorporated in their SATA storage lineup, so you can get up to 42TB in only 4U for as low as $1,250 per TB. According to Nexsan, this makes the capacity of their SATABeast the highest of any RAID system available today.

The Truth About SATA Storage: Separating Perception from Reality

(Note from Uri: Today’s post is contributed by RADirect Systems Engineer Steve Insdorf)

“You take the blue pill and the story ends. You wake in your bed and believe whatever you want to believe. You take the red pill and you stay in Wonderland and I show you how deep the rabbit-hole goes. Remember -- all I am offering is the truth, nothing more.”

Yes, this is absolutely an overused movie reference (it’s from “The Matrix” if you’re stumped). However, it’s a very appropriate starting point for this entry.

One of the greatest points of debate in data storage is the interface with which the drive is allocated. FC and SCSI drives have generally been granted ‘enterprise’ status by the industry because of their greater throughput and perceived higher reliability as compared to IDE/ATA or SATA storage. But things aren't always what they seem.

An interesting data storage site called storagemojo.com recently summarized a study by Bianca Schroeder and Garth A. Gibson from Carnegie Mellon University entitled: "Disk Failures in the Real World: What Does an MTTF of 1,000,000 Hours Mean to You?"

One of the key take-aways is as follows:

“Interestingly, we observe little difference in replacement rates between SCSI, FC and SATA storage drives, potentially an indication that disk-independent factors, such as operating conditions, affect replacement rates more than component specific factors.”

In layman’s terms, what this means is that the PC you have at home stuffed under your desk with little ventilation, and the laptop you throw into your car after a long day at work, more than likely have disk drives based on IDE/SATA technology. Ironically, these drives are often as reliable as their FC or SCSI counterparts carefully secured in their rack mounted cabinets in temperature-controlled data centers.

So, despite what some companies with obvious agendas work hard to make us believe about SATA storage performance, there’s no doubt in my mind that it is absolutely enterprise-ready.

Tape Backup Systems Are Obsolete!

Remember the days when we used tapes (cassettes, VHS) as our preferred media? In the mid-nineties we moved to CDs and DVDs. Today we are moving into the real digital age with MP3, MP4, MPEG, video streaming, etc. - all digitized, stored and accessed from flash, RAM and hard drives.

Let me remind you what is wrong with tape backup:

- It’s slow (recording, rotating, etc.)
- Quality is relatively low
- It’s not reliable (how many of your tapes fell apart or got lost?)

Proponents of tape backup systems try to address these inherent problems by offering engineering work-arounds, but there’s little they can do for issues like data restoration capabilities and slow recovery windows.

So here is the question: If you already moved your personal media files away from tapes into the digital age and are now synching your iPod with your laptop (e.g. disk-to-disk backup), why on earth would you treat your critical data/data center any differently?

Today as RAID storage is becoming more and more affordable, drive capacities are rapidly increasing (1TB per drive!!) and other factors continue to drive the shift to disk-to-disk architecture (auto MAID, replication / data recovery, WORM), I really can’t think of any good reasons to use tape backup systems any more.

If you think of any reasons, I’ll be very happy if you can share them with me!

SATA Storage by Nexsan. SATA Storage by Whom?

At RADirect, we often encounter instances where our solutions are in direct competition with ones from the ‘big players’. You know, the huge corporations frequently known by 2-3 letter acronyms with big branding, marketing and sales muscle.....

This often presents a challenge, as many customers are risk averse; I think this is a natural course of human nature. We are uncomfortable detaching ourselves from our respective comfort zones and feel more secure when we follow the herd…and are willing to pay a major premium for that.

Nevertheless, innovation and progress rarely come from followers; rather, they come from individuals who have vision, passion, and the courage to go outside their comfort zone and follow their instincts and beliefs. Those are the people that will show you how you can accomplish an objective rather than tell you why a certain objective can not be reached. Those are the individuals that grab the ‘opportunities’ rather than focus on ‘limitations’… those are the individuals that drive progress and change.

Last Thursday, I visited one of our clients who happens to be just this kind of individual. Mike Parks is the CTO of DataPipe, one of the fastest growing providers of managed hosted services with a global reach.

Our relationship with DataPipe began about a year ago, and it was slow going initially. The company’s storage infrastructure was predominantly NetApp and HP, and getting the opportunity to present Nexsan’s SATA storage systems was not an easy task, even though Nexsan’s price advantage was significant. We knew we had a shot, but needed to wait for the time to be right.

This right opportunity arrived last September, when through the insight of Mike Parks, DataPipe re-engaged us with a backup/DR application for one of their clients.

The main driver for this renewed engagement was our ability to provide a cost effective, enterprise class SATA storage system with RAID 6 capabilities - at roughly half the price of a comparable RAID system offered by another manufacturer (who shall remain nameless).

Another important attribute was the simplicity of our solution. Our solution is seen by the OS (any OS for that matter!) as just a huge disk (yes, RAID 5 or RAID 6 enabled, dual power, dual FC controllers, hot swappable, and everything you would expect from an enterprise class SATA storage system).

So Mike gave our technology a shot – we sold DataPipe their first Nexsan SATABeast system late in 2006, and since then, our business with DataPipe has thrived.

In our last meeting, Mike told me that he is still astonished that since deploying the SATABeast, he has not experienced a single drive failure or any downtime whatsoever. And the performance is excellent (in Mike’s own words)!

Beyond the obvious impact this has on our own business, I take personal pride whenever we see such success stories.

If you, like Mike, are that person with a clear vision and a good understanding of what you want to accomplish, and appreciate the possibilities technology has to offer you, I’d like to use this opportunity and express my personal ‘kudos to you!’. Innovation and progress could not occur without you.

Welcome to Information Lifecycle Management

Everyday at RADirect, we speak with storage and IT administrators about their struggles to plan, deploy and protect their data. Almost everyone is still thinking about data: data archiving, data redundancy, and of course, data restoration.

The good news is, if you are using a disk to disk backup architecture, you now have more options. Today there are two basic topologies that define disk-based digital archiving.

The first (and most familiar) option is to deploy a RAID storage system at your primary facility and a second RAID storage system in a DR facility and duplicate/replicate the data between the two. This can be a software or hardware-based solution (we often recommend a V-Switch/GDR scenario). Here, it’s important that you take snapshots, allowing you some restoration points. You should also have a solid plan for how to restore data from your DR facility in case of an expected or unexpected event.

While the above scenario is well accepted and will fit many applications, there is now a more comprehensive and intuitive way to achieve the same result - using an information lifecycle management (ILM) appliance.

ILM appliances, typically based on CAS (content addressable storage), are changing the storage paradigm, introducing a completely different way of thinking about data backup. The focus really is shifting to information lifecycle management.

Because we are now managing information, not just bits and bytes, all of the following are critical:

Restoration – Your information should be accessible every time, all the time, in an online archive. And available for reacquisition in full file format.
Retention/Disposition – You need to be able to set retention policies to handle the information, and adjust them as the value of your information changes over time.
Authenticity and Integrity – All of your information should be accurate, self-audited and secured.
Regulatory Compliance – The solution should enable compliance with all major regulatory requirements (HIPAA, SOX, etc.).
WORM – Support for “Write Once Read Many”, so that storage waste is minimized.
Searchability – You can search for information when you need it, and instantly restore if you need to.

Nexsan’s Assureon ILM appliance can handle all of these requirements and then some. So thinking about information and its inherent value (and lifecycle) is no longer a technology or feasibility question - It’s a question of user adaptation. Are you ready to manage information, not data? I’d love to hear your feedback.

P.S. If you are using tape libraries or DVDs for your backup, recovery and archiving applications, you are two steps behind. I’ll talk about this more in one of my next postings.

Lessons Learned - The Hard Way

I promised this blog wouldn’t be just about all the great things we do and all the knowledge we gained and can share with you. It’s going to be about our mistakes, too. So here’s one:

About a year ago, we started to work with a new customer, the CIO (let's call him 'Roy') of an organization that provides data repository services for regional hospitals and healthcare providers. Roy's project involved the creation of a global data replication system that included storage for a PACS system in the main data center, with a backup system for the imaging files in a disaster recovery site.

We began the sales process, like we always do, by understanding the environment, objectives, budget and growth requirements, along with many other factors associated with a well thought-out project planning process. We then designed a solution based on the latest software release of one of our storage vendors, which although in beta, happened to address all the requirements of this particular project. We communicated to Roy that our solution was a beta revision of software, and offered some financial incentives to him for agreeing to be a beta user. We articulated the benefits of the solution and explained the main principals of this architecture, the pros and cons, etc. Everything was according to plan.

Everything? Did I mention risk? We’ve been in business for quite sometime, seen many beta installations, and have come to have certain expectations of them. Typically, you may find some minor GUI glitches, perhaps some small bugs, and sometimes some other non-critical issues that can be resolved almost instantaneously by the vendor as soon as they are identified.

Well, this installation was a disaster! Nothing worked correctly, and we made numerous mistakes in trying to rectify the situation, perhaps even making matters worse. It took us about two months to stabilize the main data center site, and another ten (yes, 10!) months to get to the point where we were 100% confident that this ‘new’ software release worked as promised.

You would be correct in assuming that Roy did not want to take another risk until we had stabilized and tested this new software revision with numerous customers, so we held off on implementing the installation at his remote data replication site during this time. For nearly a year, Roy had only a single instance of the repository of his images, albeit on a RAID-5 array.

I’ve stayed in touch with Roy throughout this entire year, calling or emailing him almost every other week. I have kept him up to date on the vendor’s progress with the software and the status of other implementations using this feature. I also set up several conference calls with Roy and the vendor so we could all set new expectations, re-define the objectives and agree on our ‘next steps’, making sure all three parties were always in full agreement.

Needless to say, I’m not proud of this project! Roy – this is not the first time you’ve heard this from me, but I’m terribly, tremendously, dreadfully sorry for this experience! If I had ever suspected that this could be the outcome of our experience, I would have never put you through this.

SORRY!

Lessons Learned - The Hard Way:

1. Avoid being a beta customer, unless risks are low and financial gains are high.
2. Testing is important. When the stakes are high, do more testing upfront.
3. If possible, leave yourself a contractual ‘escape’ route to mitigate the risks of a newer technology.
4. Speak to references that are using the same technology for the same application.
5. Speak with references using the same people/resources. Validate that the human factor is trustworthy and knowledgeable.
6. If you happen to be the exception, make sure you re-write your ‘contract’. It is important to redefine objectives, timelines and financial gains/penalties throughout the experience.

Exceptions happen to everyone! What we at RADirect do with them and how we use them to improve our internal processes and decrease our bad incident rate, I’d like to think, sets us apart.

Planning Storage Networks?

So what is the most important factor you should consider when planning storage networks? Is it IOPS as Robin Harris claims in his computerworld blog? Or is it capacity?


How fast is fast

How fast is fast?

Ask yourself this: “If I can pay for a Lamborghini that goes 0 to 60 in under 3.0 seconds, should I buy one?” Most of us see this amazing $150k car and realize that it does nothing for our real world application (e.g. driving to work and back), except for stimulating our senses and heightening our egos. Then we ask ourselves:
1. What am I going to use this car for?
2. How much can I afford to pay upfront (CAPEX)?
3. What are the expected recurring costs (OPEX) to keep this baby running?

Finally, we come to the conclusion that the average $30k-$40k cars are really a much better fit for us. For that price, we can get a nice SUV with a built-in DVD player, a navigation system, a great sound system and reasonable MPG efficiency. You could probably even add some additional features that you think are important like ABS, 4x4, sunroof, leather seating, etc.

The best part, if you follow this line of thought, is that you’ve just saved some serious change (over $100k, or 75% of your CAPEX, in this example) to use on your other, more critical applications (perhaps the dream vacation you always wanted to take? a new deck? your daughter’s college tuition? all of the above?), They can be more important and productive expenditures according to your OWN set of priorities. That’s why the majority of us are still driving the more sensible cars. Unless, of course, we have unlimited funds and absolutely no concern about budgets and other usages for it.

The same planning process should apply in the storage arena. One should determine the best solution for a particular storage networking application by considering all the factors together; IOPS, capacity, features, cost, etc. This approach ensures higher efficiencies and better utilization of resources WITHOUT jeopardizing application requirements.

On our website, we try to highlight the most common and important planning factors for our customers, and include datasheets and whitepapers wherever possible. But the real work is best done in consultation with an experienced systems engineer who specializes in storage applications, has planned, implemented and operated dozens of installations, and can help you define your own critical parameters while maintaining reasonable associated TCOs.
