THE STORAGE NETWORK HOSTED BY MARIO APICELLA



August 31, 2005

Opening the Zetera box

One of the hottest things I ran into this year comes from a startup company in California, Zetera, and is a completely new twist on networked storage.

I mentioned Zetera in two of my Storage Insider columns, in February
when they first left stealth mode, and in June, when they made a joint distribution agreement with a storage software company, DataPlow.

Why am I mentioning Zetera again now? Because Netgear is about to launch Storage Central SC101, the first product based on that technology, actually the combined technologies from DataPlow and Zetera, and I have one in my lab for an early peek.

SC101 is an entry-level product, but I can't wait to see this new UDP-based storage networking in action. Interested to know how it went?

Then let's go.

The box SC101_front_lowres.jpg carries both the Zetera and Netgear logos, as it is the result of their partnership. It's essentially add-on storage for consumers and SOHO users but, differently from other products in that space this two-brick sized box connects to your Ethernet network and not to one of the ports on your PC.

In the back the unit has receptacles for a power cord a for an Ethernet cable, but no power switch. SC101_back_side_lowres.jpg
On the front, three led to monitor power, disk activity and network activity. Removing the front cover reveals slots for two 3.5" IDE disk drives.

I have two 160 GB Maxtor drives waiting for a mission just like this and, after setting their jumpers to "cable select", in they go. The two drives slide in their slots with a snug fit and without requiring screws to secure them to a chassis.

The space around those two slots is indeed very tight and I hope that the heat will be properly dissipated through the two 3" wide aluminum grids that run across the top and the bottom of the box.

However, four small feet keep the unit 3/4" above my desk and the installation instructions suggest (appropriately) to be sure and keep that space clear.

I connect the RJ45 cable to my 1GbE switch and power on. In addition, I install Storage Central Manager, the management software, on my XP machine. It runs also on Windows 2000 but the latest SP is a requirement for both OSes.

Storage Central Manager volumes on first drive.bmp runs in "wizard" or in "expert" mode. Choosing wizard gives the choice between creating a new volume, changing properties for a volume, or mounting an existing volume.

After clicking my obvious choice, "create", the GUI opens a screen listing my two drives with an IP address attached to each of them.

It's easy to retrace what happened: for each drive the Zetera chip acquired an IP address from my DHCP server. I have now two networked drives, visible from any machine on my LAN, and both addresses respond to my ping.

Back to creating my new volume, I select one of the drives and click next: The wizard reminds me which drive I have chosen and how much space I have left on it, then asks for a name and how big I want the new volume to be.

Plain stuff so far, but the next question is "do I want mirroring?", and when I answer yes, the wizard proposes to mirror the content of the new volume on the second physical drive in Storage Central.

Obviously mirroring is expected to preserve the volume content if one of the drives fails, a feature that I 'm going to test later on.

The next question is "do I want to share the new volume?" . Answering "yes" will make the volume accessible also from other computers, as long as they are on the same LAN and run Storage Central Manager.

Answering "no" is the selfish choice that will restrict using the new volume to just this machine. I answer yes, then yes again when asked if I want to password-protect my new volume: users from other machines will have to enter the correct password to gain access.

After a few minutes my new volume appears under My Computer in Windows Explorer and at the same time Storage Central tells me which letter has been assigned to it.

From Windows Explorer I launch a copy of numerous files to the new volume, then, while the copy is still running, I install the management application on another machine.

I then mount the same volume also on my second machine and open one of the files: the first machine is still copying other files, unaffected by what I am doing on the other PC.

Differently from other SANs(storage area network), the Zetera approach makes sharing files easier rather than more complicated, which is a major plus for the target audience of the SC101. In fact, sharing a volume with Zetera is easier than using the standard Windows tools.

Looking at my clock, the elapsed time since I started installing the software on the first machine is only a few minutes, which is an indication of how easy and quick was adding a micro-SAN to my LAN.

I use the term micro-SAN loosely, because according to Zetera a network based on these "bricks" can expand up to 128 PB (petabytes).

Should I dismiss that claim as theoretical or just marketing blast? Perhaps, but it's undeniable that I can add a drive for each IP address my DHCP server can dish out.

Even using low capacity say, 120GB drives this "micro-SAN" can potentially scale extremely well, probably larger than any user will ever dream to deploy.

Starting early September you should be able to buy one from one of the major retail outlets (think Fry's CompUSA, Staples).

I promised not to spill the beans about price before then, so I'll leave my comments on that for another post, together with more testing experience and some pros and cons.

Meanwhile, please let me have your comments.

Desktop class RAID has been a PAIN for many years

Says Michael Lueck from Lueck Data Systems in response to this Storage Insider column: Simplifying SATA RAID

But let's hear from his own words.

Greetings Mario-

It will be interesting to see how Silicon Image plays out this "new" desktop RAID chip technology.

Desktop class RAID has been a PAIN for many years now. PCI-X is not helping matters any as desktop class boards have 1x and 16x slots, with the 16x taken by the graphics boards. Real SATA RAID boards need an 8x slot which is only found on dual processor workstation / server class boards... and then the graphics typically stink.

I say it will be interesting to see how they deal with the RAID for desktop class as there is quite a bit of RAID out there on desktop boards, but it is always this BIOS tricking Windows-centric junk that I would not trust anything to, and like I inferred already is Windows-centric.

To be fair to Silicon Image, their chip is OS agnostic but the OEMs could decide that Windows users are a more attractive target. In my opinion, setting up a RAID card should be a no brainer for a person smart enough to install and manage a Linux desktop.

But let's put Michael on again.

I end up having to stick a 64-bit 3ware controller in a 32-bit slot for now to get a low cost SATA mirror into low-cost firewall boxes.

Being a performance nut, I hate seeing 32-bits hang into thin air, but vendors have really backed the industry into a corner of restricting real hardware RAID away from desktop class computers.

I am as anxious as you are to see this new chip at work. Mirroring (RAID 1) should become a minimum requirement on all laptops and desktops. A single disk drive should not be trusted to reliably store any single-copy file.

Thank you for those provocative comments, Michael.

Protecting Your Company Against Catastrophic Data Loss: Five Things Small to Midsize Businesses Need to Know

If you've been thinking that it's time to do something to bullet-proof your small-to-midsize business critical data and systems such as financial transactions, patient records or your email and Web retail storefronts you've been thinking right. Fifty percent of companies that lose their data go out of business immediately and ninety percent don't survive more than two years, according to research firm Baroudi Bloor International. That's a lot of unnecessary risk for something so preventable.

The causes and instances of data loss are much more commonplace than you might think - it's rarely an act of God. In fact, it's usually just an easily corrected system or user error, if you've protected your data correctly. Only three percent of all data loss is caused by fire, flood and other such disastrous events. The most common causes are hardware or system malfunction (44 percent), human error (32 percent), software corruption (14 percent) or viruses (7 percent).

There are very good reasons for protecting your important business data, according to Bob Schaefer, CEO of Breece Hill, whose company manufactures iStoRA, an integrated disk and tape-based backup, recovery and archiving appliance. "Obviously, you need it to run your business. But beyond that, businesses face a growing list of strict legal requirements, and the need to be prepared for any potential lawsuits or audits that might follow events such as an employee termination, worker injury or the sale of the company."

Here are Five Things to Know:

1. Backup Often and Wisely
Market research firm Gartner says that less than 1% of small businesses perform daily backups, and Enterprise Strategy Group analyst Peter Gerr says that backup is always at the top of business concerns - it either takes too long, or users can't verify that it's actually working.

Backing up everything on a daily basis can be extremely costly and time-consuming, so it's important to identify only the data that changes. For the average business, the percentage of data that changes daily is somewhere between 2-5%.

For example, a graphic arts agency that develops intricate print designs and continuously backs up large image files, page layouts and video work will quickly break the bank on storage hardware alone. By implementing a backup function that's able to sense changes reasonably well and back up just those files that have been altered, the business is protected at far less cost.

On the other hand, a specialty manufacturer of high-end audio products may only need to backup once a day, but will require it to be a bullet-proofed backup. While the rate of change is slow, each order is vitally important to the business.

"By limiting what your business backs up to only that which changes daily, huge time and cost savings can be made," said Schaefer.

2. Prioritize Data for Disaster Recovery
Another aspect to backing up data is making sure that the systems and data your business absolutely needs will be there in the case of a disaster. This means that you need to look at your overall data picture, and decide what's critical, what's important, and what you can do without. It's critical that an online retailer keep its Web store up and running, but it can do without its print services, at least for awhile.

So the next step is to prioritize each system and its related data - key systems for most small businesses include email, telephones, databases, file servers and Web servers. Typically, systems are prioritized into three categories that require differing levels of recovery time, from zero to days: redundant (immediately), highly-available (minutes to hours), and backed up (four hours to days).

"As a manufacturer of high tech storage products, including the iStoRA appliance, we have a high rate-of-change that forces us to keep more data on disk for immediate restore than many other businesses," comments Breece Hill's Schaefer. "For us, it's essential to keep our most important data, such as engineering drawings, supplier specifications, and up-to-the-minute materials pricing, on disk for at least three weeks."

3. Archive Important Data for the Long Term
Now it's time to consider your data archive. First, you'll need to figure out how long to keep data. Federal and state regulations and policies dictating the length of time that your data must be retained vary by state, and can be anywhere from seven years for equity or stock transaction records, to 17 years for certain HIPAA regulations, and up to the life of a patient for others.

Government contractors or companies working with government contractors, face other requirements, including the type of media used. Optical disk, for example, can survive the electrical pulse that follows nuclear war. But in most other cases, it's simply important to choose a system and/or storage location that will achieve your company's needs. But remember, penalties for non-compliance with data retention requirements are stiff.

If you're going to have to keep data for twenty years or more, you'll need to identify a physical storage location. Some businesses will choose a full-service company such as Iron Mountain, that picks up, stores and delivers data when it's needed. But it's more realistic that the data goes offsite, and is stored in the safety of person's home.

"But remember, however you choose to store data," said Schaefer, "it must be stored in a climate controlled and electrically neutral environment."

4. It's Smart to Comply Now
There's been a lot of buzz in business and industry media recently about 'compliance.' What it really means for the small business is that you'd better know what regulations affect your business, and what that means for your data storage system.

Some of the most important recent regulations to affect the small-to-midsize business include the Sarbanes-Oxley Act (SOX), which has implications for financial reporting, and the Health Insurance and Portability and Accountability Act (HIPAA), which applies to the maintenance, security and storage of health care records. There are also a variety of human resources-related regulations applicable to programs like worker's compensation at the state level, and payroll regulations such as the Federal Insurance and Contributions Act (FICA) at the national level.

Compliance requirements are tightening across the board. For example, if your business sells bolts to Lockheed Martin, you may be required to comply with stricter Department of Defense regulations for military contractors. The same is true for independent broker/dealers and the Securities and Exchange Commission, service providers to major utilities and Homeland Security regulations, as well as small-to-midsize businesses and local, state and federal regulations of all shades.

"The bottom line is, you had better comply," adds the Breece Hill executive.

5. How to Store Data Cost-Effectively and Easily
Most small-to-midsize businesses don't have free IT resources to set-up and manage a storage solution, so it's important to work with a value-added reseller that understands your business. It's also important that the solution fit easily into your company's existing system, and is as manageable and turn-key as possible.

Over the long run, most mid-size businesses are better off buying an integrated solution. The upfront cost may be a bit more, but in the long run, the time, money and effort spent on a custom, or 'home-grown' solution will be far greater. Not only will you need a professional to install it, but they'll need to help maintain and tune it as well.

Today, there are all-in-one storage appliances that include integrated disk for short-term backups and archiving; tape for long-term archiving; as well as the software and server components that that help to prioritize and store data appropriately such as Breece Hill's iStorRA.

"The beauty of the integrated appliance," concludes Schaefer, "is that you have all of the storage media components in a single box that's easy to use. And if anything goes wrong, you've got just one number to call 'one throat to choke.' "

So there you have it- the basics for protecting your business from the very real threat of catastrophic data loss. When researching solutions, make sure that you work with a professional or value-added reseller who's familiar with your type of business as noted above, data protection requirements do vary significantly, depending on your industry. And remember, without your business' data, there is no business at all.

How vulnerable are you today?

No, that's not a new tag line from a Microsoft ad, but a question that can now be answered with a little more awareness.

The topic is obviously protecting your computers from cyber crime, a task that we have grown used to delegate to things such as virus protection software or firewall systems.

That's not a bad approach, because frees precious IT time that can be better applied to taking care of business rather than patrolling the company cyber borders.

The down side is (yes there is always one) being less aware of actual threats and protection measures. For example, can you tell what vulnerabilities are you exposed to with, say, your backup application?

Probably, not. Well, now you can find out rather quickly, thanks to a new comprehensive National Vulnerability Database that consolidates known weaknesses collected by many public sources.

Let me quote from the horse's mouth: "NVD is a comprehensive cyber security vulnerability database that integrates all publicly available U.S. Government vulnerability resources and provides references to industry resources. It is based on the CVE vulnerability naming standard."

I was rather shaken after spending some time searching NVD: may I suggest that you do a few queries too?

The database is updated daily with newly found threats and weaknesses. Check it out: it may be scary to know your exposures, but not knowing them is certainly worse.
