One of the differences between IBM and the other storage vendors is that IBM is also in the business of middleware, application-aware backup software, and advanced copy services. This allows IBM to put togethersolutions that work to address specific challenges for our clients.
IBM has written a whitepaper on a cleverVSS Snapshot Backup for Exchange using IBM Tivoli Storage Manager and the point-in-time copy capabilities of IBM System Storage disk systems.
A problem in the past was that each vendor's point-in-time copy method had its own unique proprietary interface.Microsoft Developed Volume Shadow Copy Services (VSS) as a common interface front-end to resolve this concern.IBM Tivoli Storage Manager for Mail can invoke standard VSS interfaces, and this in turn can invoke FlashCopyon the IBM System Storage SAN Volume Controller, DS8000 series, or DS6000 series disk system.
You might be thinking: Wouldn't it have been less effort to just have TSM for Mail invoke IBM proprietary interfaces,rather than having to put full VSS support into TSM for mail, and then full VSS support into IBM's various disksystems? Perhaps, but IBM doesn't decide to do things because it is the cheapest way, we focus on what is theright way, and in this case, customers now have more choices, then can use TSM for Mail with IBM or non-IBM disksystems that support the VSS interface, and IBM disk systems can be employed into other uses for VSS snapshot.
Of course, we would like our clients to consider both TSM and IBM System Storage disk systems for a combined solution,not because they are required to make the solution work, but because both are best-of-breed, and whitepapers likethis show how they can provide synergy working together.

Well it's already Tuesday here in Australia. Many people here have asked me what my secrets are for dealing withJet Lag
, as many Aussies (and Kiwis) travel across time zones for business. While Sydney is 17 hours "ahead" of Arizona right now, my body feels like it is 7 hours of time zones "behind". If you do nothing, your body will naturally adjust, about one time zone per day, which is completely unacceptable for most week-long business trips.Since I have been traveling for IBM since 1989, I have read a lot on this, and tried a lot of things, and here's what works for me.
Disclaimer: I am not a doctor, consult a doctor if you have any questions
- Before the Trip
People are normally on a 24-hour circadian rhythm. Change this to 48-hours by alternating light-eating and heavy-eating days. Why? a 7-hour shift to a 48-hour cycle is not as bad as for a 24-hour cycle. A Light-eating day may involve a light breakfast, light lunch and either no dinner or just appetizers. A heavy-eating day involves bigger meals, and perhaps snacks between meals. Plan to have the day you step on the plane as your last light-eating day. I normally start this 5 days before the trip.
Adjust your drinking schedule.
- Before noon, drink water and juice only, no caffeine, no alcohol, no shots of tequila as morning mouthwash. My drink of choice in the mornings on airplanes is spicy tomato juice, which some people call "Bloody Mary Mix" without the alcohol.
- Noon to 4pm, drink caffeinated products, like coffee, tea or soft drinks. If you normally don't drink caffeine at all, here's your reason to start. It will "center" your day.
- After 4pm, drink alcohol, like red wine which is good for your for the health of your heart and lungs, but no caffeine, cola-based mixed drinks or late night cappuccinos. If you normally don't drink alcohol, drink water or juice instead.
This revised drinking schedule is good advice year round, wherever you are, but you can start this 5 days before the trip also.
- During the Flight
Immediately upon getting seated, adjust your watch to the destination time. This will help you determine when you should be awake or asleep on the flight. For example, I left 10pm Los Angeles, and arrived 6am into Sydney. I reset my watch to 3pm had my first meal, stayed awake to watch a few movies, slept for 6 hours, and then was awake the last two hours before landing for breakfast.
Sometimes, this time adjustment might mean sleeping through dinner or breakfast served on the plane. Survivalists indicate that people cansurvive on several weeks without food, and most American businessmen carry enough body fat to hibernate through winter, so don't feel bad skipping a meal. Some airlines provide "don't wake me up" stickers you can attach to your seat or shoulder. I also tell the people around me "If I am asleep DON'T wake me up for drinks or meals." Despite this, people will wake you up anyways, and if this happens, be pleasant, indicate again that you are not hungry, and prefer to sleep instead.
The drink schedule applies to the new time zone on the plane. Depending on when you are served, drink water, juice, caffeine, or alcohol, based on the destination time zone.
- Once you arrive
Focus on being awake from 9am to 5pm in the new local time zone. You can then work to adjust your hours from there.
For at least the first three days at your new location, eat high-protein breakfasts and lunches, like eggs and meats, which will keep you more awake. The drinking schedule still applies, so no coffee or tea in the morning, but some during lunch is fine, again to "center" your day. Eat high-carbohydrate dinners, like salads, vegetables and pasta. No caffeine, have alcohol, juice or water instead.
Many say that it is best to be in bright sunlight during the day, and darkness at night, to reset your circadian rhythm. Scientists have suggested your sensor is in the popliteal region (backs of your knees) and is discussed by The Straight Dope. While I have never strapped aflashlight to my legs, I do find wearing shorts or bathing suits and being outdoors during the day, and wearing long pants and being indoors in dark conditions during the night to be helpful. If you take a nap during the day, make sure your drapes are wide open and sleep on your belly, letting the backs of your knees to get plenty of sunlight, to remind your body you are taking a "day-time" nap. If you find yourself awake at night, keep your legs covered under the bed, wear long-legged pajamas or sweat pants, use minimal lighting like a bedside night lamp, to remind your body you are "reverse napping" (being awake for a short time during a sleep period).
Exercise in the morning. I do this in Tucson, so it is routine and habit to continue at the new location. Sometimes just walking around your new surroundings can be enough to help you adjust to the new time zone, and is a good excuse for wearing shorts or your bathing suit.
About 3-5 days before returning, go back to the "Before the Trip" process and start alternating meals again. Follow the process and act as if returning home is a new trip to deal with jet lag in the reverse direction.
Well this is what works for me, I don't take "melatonin" or other drugs that have been found useful for jet lag in hamsters. I welcome comments on what works for you.

Well, I'm going to take a two week break from blogging. Not because my clarification of storage terminology got me Marc Farley's finger wagging of shame
No, I'm going on vacation.I'll be going to a third-world country, possibly outside the reaches of cell phones, e-mail and the internet, so I won't be blogging until I get back later this month. Since Clark Hodge has discovered a pattern that I am suspiciously close to massive power failures, I think it best not to tell people exactly where I am going.
So, until I get back, I leave you with a nice piece from Kirby at Storage Sanity who has discovered that IBMers are very nice.
I'll spend my time doing non-storage related activities, like practicing to catch sunglasses with my face.I'll be back in a few weeks.

The results are finally in. IBMer Wolfgang Singer was awarded "Top Speaker" award for his NAS and iSCSI tutorial at last year's Orlando 2006 conference. Here he is receiving the awardfrom SNIA Executive Director Leo Leger.
Of course, NAS and iSCSI technologies have been around for a while, but they are still new formany customers, which is why tutorials like this are so important.
Not everyone is clear on these technologies. For example, Dave Hitz asksis iSCSI SAN or is iSCSI NAS? I Don’t Know.
To avoid this confusion, IBM adopted clarifying technology.
- When iSCSI is intermixed with NFS, CIFS and other TCP/IP messaging traffic, it's NAS.
- When iSCSI is run on its own dedicated network, for security and performance reasons, it's an IP SAN.
The advantage of IBM System Storage N series "unified storage" concept is that you can choose which method of attachment you prefer.

Today was the "First Ever Live Virtual Virtualization Tech Fair" sponsored by IBM and VMware. This was a 1-day event hosted by Unisfair.
The day included presentations done at a conference call, along with exhibition booths.
We had an exhibition booth exclusively for "storage virtualization" featuring our IBM System Storage SAN Volume Controller (disk virtualization) and IBM System Storage TS7520 Virtualization Engine (a virtual tape library, or VTL).
People who were logged in were represented in silhouette form. When someone walked into the booth, our army of "booth reps" were able to chat with them and answer their questions. They could also peruse the various online materials we made available about each product.
Here are some of my observations:
- A lot of questions were related to IBM's support for VMware. Although VMware is now currently owned by EMC, pending a spin-off IPO, IBM is its biggest reseller, given IBM's vast experience in server virtualization. Ironically, IBM's SAN Volume Controller supports VMware better than EMC's own storage virtualization product, Invista.
- This was a good opportunity to discuss all the other forms of server virtualization available, such as Xen, Microsoft Virtual Server, Advanced POWER virtualization inside our System p server line,and running thousands of virtual servers on our System z mainframe machines.
- People also familiar with Second Life thought this 2-D "silhouette" version eliminated the need to configure and dress up your avatar as is required in participating in Second Life events. However, being only ableto chat, send e-mail and show web pages seemed less immersive than what Second Life can offer.
- This event generated over 60 leads. We will pass on the contact information to the appropriate sales team.
