ACME 2005
By
Hunter Metatek
at 07:32 PM
With the Survivor's Guide to 2005 NWC issue hot off the presses I wanted to pass on details as to what we are focusing on at ACME in the IT shop for 2005. We have some big multi-year projects still ongoing and some things we started in 2004 as well as new projects for 2005. In the past we made the mistake of approaching budgeting as a "wish list" and then figuring out if we had the staff to execute the projects. This year we took a more realistic approach. Keep reading to see what amazing things we have planned for 2005.

They Just Keep Getting Bigger--Maybe
By
at 08:28 AM
According to The New York Times, Symantec and Veritas are in discussions aimed at having Symantec purchase the company best known for its data backup packages. Like so many of these stories, there are obvious story lines, and those that are a little more subtle.
The obvious story line is that the number of players in the security market continues to decline as mergers and acquisitions continue at a goodly clip. There are, of course, aspects both good and bad to consolidation, but financial and market forces seem to be moving in the "fewer/larger" direction, so there's little constructive that I can say about it. The less obvious story line actually has more meat, in my opinion; security is gradually moving from asset protection to business continuity assurance.
Think about it: Most security is focused on keeping "the bad guys" from succeeding in their dastardly deeds. Business continuity doesn't really care so much where the threat comes from, it just wants to keep software, hardware, and data assets available and useful to the proper users. Assurance includes security, but doesn't stop there, extending to backup and restoration, disaster recovery, maintenance, regulatory compliance, and a host of other issues. At a recent conference I noticed more people handing out business cards that read "Data Assurance" or something similar, and it's a trend that can work for the security professional on a number of levels.
First, the change in scope can mean that you have meaningful control over more aspects of the network infrastructure, so that security stands a chance of being built into, rather than bolted onto, the network. Next, the greater responsibility can translate into larger budgets--seldom a bad thing in the corporate world. Finally, taking a broader view of assurance can make you much more effective in designing security--the extra work and responsibility can carry some solid professional benefits in horizon-broadening.

SANity Prevails
By

at 10:08 PM
So Tim Wilson at NWC wrote in the current issue about how to negotiate with vendors. And I also noted the article from Don MacVittie about SAN Switches. At ACME we just got finished with a grueling few months of back-and-forth negotiations with SAN vendors.

More Security Consolidation
By
at 02:09 PM
The push to consolidation in security continued today as 3Com purchased IPS vendor TippingPoint ** for somewhere in the neighborhood of 430 million dollars. According to the announcement, TippingPoint will continue to operate as a separate division of 3Com, with its headquarters remaining in Austin, Texas.
So what does this mean to the world of security? In one sense, it's just the latest step in the march of security to the network infrastructure. Cisco is the loudest voice talking about the virtues of tying security to the switches and routers at the core of the network, but it's far from the only voice. With this acquisition, 3Com has put some serious money behind this kind of talk, and it's reasonable to expect that they will ultimately tie the products together more closely. There's no surprise in this, but I do think there's good news for security-conscious folks in the small- to medium-business category.
While most of the companies talking about security and the infrastructure have been focusing on products in the enterprise space, 3Com has built a reputation in the SMB market over the last few years. 3Com has also been introducing more products aimed at security, so the company has obviously seen an opportunity to make a market within security-conscious SMB I.T. folks. This is great news for those who have significant concerns about security within smaller companies. TippingPoint is a very solid IPS product (as I found when performing tests for an IPS review that will appear in Network Computing in January), and linking the thinking with 3Com's presence in the SMB world should mean nothing but good things for migrating security capabilities down-market.
I'm looking forward to seeing how 3Com works with TippingPoint as part of the corporate fold. If today's purchase means that a 200-seat busines can get serious intrusion analysis, detection, and prevention, then this is good news for the networking community. I'm going to remain optimistic at this point, but I still have some phone calls to make--I'll let you know more after I have a chance to talk with the folks at 3Com and TippingPoint.
** In the original version of this post, CheckPoint was erroneously identifed as the company purchased by 3Com. Thanks to alert readers who pointed out the error.

Someone has way too much time on their hands. Both the guy who did this and my brother, who somehow managed to find this obscure link.
Someone over at the Goldfish Online has recreated working logic gates in LEGOs.
You can check them over for accuracy here
Perhaps we'll see LEGO kits for this available for purchase for the geek in your life? We could only hope...

Upgrading Critical Storage - the first round
By
Don MacVittie
at 10:29 AM
Yesterday we put the Snap 18000 into the rack with the NSS, configured it to match the network, gave it two network connections, and configured the storage. We then did an initial copy of the NSS shares onto the Snap.
Plenty of the work outlined in "The Plan" taken care of in a single day. Some of today's storage is a dream to configure.
But nothing ever goes exactly according to plan. Luckily the problems I've hit thus far are minimal.
I didn't get the amount of space I was hoping for out of the Snap. Why, you ask? Because I wanted a hot spare on the RAID 5, and I wanted to save space on each volume for snapshots of the existing data (Snap handles these for you if you just set up the space and make a schedule).
So my final configuration is 900 Gig for the existing data, and 256 Gig for iSCSI on two separate volumes... That's still a lot more than we had, but I should have planned for it. Now I know.
Once everything was set up, I wanted to get a baseline of the existing system in case things fell apart on me, so I tried to set up replication. Unfortunately, the product I had intended to use was a demo, not the real McCoy. I'm now looking at replication tools to bring in for this project, and in a hurry. At this time I'm looking at the replication software Adaptec sells specifically to go on the Snap, and WANSynch by XOSoft. I don't have time to widen this search out, unfortunately, and NWC Inc. will have to live with my choice for a while.
That's it for now... I leave you with a picture of the two machines together in the rack, if you're interested.
NSS and Snap, together.

Upgrading Mission Critical Storage - The Plan.
By
Don MacVittie
at 06:53 PM
This week I began upgrading the storage in NWC Inc. Since you, our readers, can access portions of NWC Inc. online, I have to take all of the precautions you do when upgrading storage.
As I upgrade the system, I'm writing a workshop about it, offering readers the opportunity to see what our problems were, and how we resolved them.
But you, dear blog reader, get a bonus. Here on the Storage Blog I'm going to "bring you along for the ride" so to speak. You'll get to hear and see it as it happens, and can leave me comments or suggestions.
For today's entry I'll give you "THE PLAN". This is the outline I laid out for accomplishing the goal.
The Plan
NWC Inc., our simulated Mid-Size enterprise has a problem. Our aging NSS NAS (named SpanStor on our network) must be replaced. Over the last several months, it has suffered more downtime than we can afford, and sometimes while it is up we cannot access data on it. This impedes business, and impacts revenues (not to mention interferes with our RealWorld testing) so we are going to replace it.
For our purposes we have chosen Adaptec?s Snap 18000. This product has received glowing reviews from NWC and NWC Inc staff (including yours truly), and we decided that if we must replace our storage, we should follow our own advice.
The project will span more than a week, and includes reconfiguring many systems to access the new storage. To minimize the amount of change being introduced into NWC Inc?s production network, we are opting to masquerade the Snap as the old NSS (as defined below). This is not a ?100%? solution, but it will take us most of the way without having to change shares on production servers. Only some support functions require that we actually change settings to access the new storage.
With all of that said, here is the outline of ?The Plan? to upgrade our storage. We will keep you updated as this plan progresses, and let you know what speed-bumps we encounter along the path to ?brand new storage?.
1. Mount Adaptec Snap-Server 18000 in NWC Inc. racks.
2. Assign IP Address in NWC, Inc. range
3. Configure Snap to be RAID 5 with a hot spare
4. Configure drives to mirror current SpanStor shares.
a. CIFs shares will be exact replica of SpanStor utilizing 1.0 Gigabytes
(currently have 650 Megabytes available on SpanStor)
b. Set aside space for iSCSI for future use Utilizing remaining
400 Megabytes
5. Set up job to bulk-copy from the NSS SpanStor to the Snap.
Configure this job to run each night.
6. Coordinate with Lori, the CIO of NWC Inc. for date to perform
actual replacement.
7. On that date,
a. Perform final copy.
b. Take SpanStor offline
c. Change IP and name of Snap to match the old IP
and Name of SpanStor
d. Bring Snap back online.
e. Reattach drives on all NWC Inc. Machines and test connectivity.
8. Configure Snap Snapshots to replicate data off.
9. Configure tape drive to back up data from the Snaps
10. Observe production environment daily for a week,
and weekly for the remainder of a month for any oddball
applications that malfunction to insure minimal impact from
this change.
Pictures of the machines in question:
NSS NAS that is being replaced. This 13.5U of machine is 640 Gig.
The new Snap 18000. This 2U of machine is 1400 usable Gig.
Next time I'll go over the early speed bumps I hit while starting to install the new server.

Finally, those SCSI/SATA performance numbers.
By
Don MacVittie
at 12:41 PM
Comparing yesterday's "primary storage" with today's Serial ATA
I know, I'm months and months late providing this data, but here it is...
The point here is that the SATA drives on the market today perform as well as the SCSI drives that we were
sold 5 years ago for "core data center" use. Granted data usage has changed, but enough that yesterday's
main storage standards aren't good enough for primary storage today? Take a look at the numbers culled
from the manufacturer's own data sheets, and you decide.
So where this data comes from. I took the data sheets for the drives named, found key performance
information, and compared them. The SCSI drives are older (3-5 years ago) models that were sold as "data
center storage" at the time they were popular, and the S-ATA drives are new today. Some vendors in the
storage industry want to tell you that Serial ATA is inferior by definition, these numbers should show you
that is just not true as a valid blanket statement. They are lower performance than SCSI drives
available today, but the numbers show they are data center/primary storage quality. Only in MTBF (for
Seagate) did we see a significant difference that was not in the Serial ATA drive's favor. In fact, the
only major difference in SCSI's favor seems to be years of warranty.
As always, I have to say that there are some applications that benefit from the performance and added
management functionality of newer SCSI drives, but for most applications, Serial ATA is good enough,
particularly when combined with RAID 5.
Maxtor/Quantum:
| Atlas II 4.5 GB SCSI | Maxline III SATA |
| Seek Time (Avg Read) | 8 ms | 9.3 ms |
| RPMs | 7200 | 7200 |
| Transfer Rate | 40 MB per second | 150 MB per second |
| Buffer size | 512 KB | 16 MB |
* Interestingly, the data sheet did not have MTBF values for the Atlas II.
Western Digital
| Vantage 9 GB SCSI | Raptor 36.7 GB SATA |
| Seek Time (Avg Read) | 6.6 ms | 5.2 ms |
| RPMs | 10000 | 10000 |
| Transfer Rate (buffer to host) | 80 MB per second | 150 MB per second |
| Buffer size | 2 MB | 8 MB |
| MTBF | 1,200,000 | 1,200,000 |
Seagate
| Barracuda 180 GB SCSI | Barracuda 200 GB SATA |
| Seek Time (Avg Read) | 7.6 ms | 8.5 ms |
| RPMs | 7200 | 7200 |
| Transfer Rate (to-from disk) | 36.1 MB per second | 58 MB per second |
| Buffer size | 4-16 MB | 2-8 MB |
| MTBF | 1,200,000 | 600,000 |

Storage Security... Looking for input
By
Don MacVittie
at 11:47 AM
We're starting up a new review, one that's going to be just a little bit different, we're going to compare the options that you have for securing your storage - not give them a head-to-head review, because there are many different types of security products out there, but give you an idea of what's available, how it works, and what the trade-offs of implementing each product are.
And we're interested in what you have to say. We're sending out a reader survey, as always, but if you're looking at the Storage Channel Blog that means storage interests you, so I'm interested in hearing your concerns about security too. Particularly if you have experienced some of the painful issues that implementing storage security can bring up, drop me a line.
Fill out the form below if you're a reader (not a vendor), and are interested in lending a hand.
Thanks,
Don.

If you're a child of the 80's (and a fan of the Transformers), or know someone who was, you'll appreciate this car commercial from overseas. If that's not an amazing use of computer graphics, I don't know what is.
One thing's for certain -- the robots in the upcoming 'Transformers' movie better look that good (though I don't expect Optimus Prime to Moonwalk.)
