Re: Any suggestions?


To update the story so far, we ended up getting Cisco involved since they monitor our WAN and they saw no problems with congestion or anything like that. I then opened a Support Request with VMware just to see what their recommendations would be. After it is all said and done, the problem seems to lie with our WAN in that it is a frame relay network. Apparently this network topology is not conducive to good RDP performance. We are scheduled to upgrade to MPLS and refresh the WAN routers but that is still a few months off. We looked into the solution from Expand Network but the prices involved were just too much for an unbudgeted expense. Come to find out...a company called Circadence had just opened an office here in Tupelo, MS and their specialty is WAN acceleration. We have met with them twice now and are preparing to test their technology to see if it will improve the RDP performance next week. I really hope this solution from Circadence works out, if not, we are going to be forced to bring Citrix back into the mix.

2 March - Chiang Mai - Chiang Mai, Thailand

entry & travel map
Chiang Mai, Thailand

We took the overnight train from Bangkok to Chiang Mai.  Second class on the way there.  It was pretty comfortable overall, though the ventilation of the sleeping compartments hasn't been designed to cope with the effects of Thai curries.

Our first night we wandered down to the Sunday walking market.  A huge popular event with all sorts of goodies, we had lots of fun until a swarm of moths descended over the entire town.  Everyone around started choking on them.  We went for a late Japanese dinner and maggots were still falling from J's trouser legs.

The next day, we take a cooking class with the sister of Mai Kaidee (a well known cooking personality in Bangkok).  Was very informative and lots of fun.  At the trip to the market we learnt plenty of interesting facts about chillis, eggplants, mushrooms, banana flowers, etc.  In 2 hours we made 12 yummy dishes including curries, soups, spring rolls, etc.  At the end they expect you to eat it all, so we gave it our best effort but admitted defeat and took the leftovers home.  Unfortunately we couldn't face eating them and ended up throwing them out a day or so later and kept away from Thai food for a few days until we recovered.  Sometimes you can have too much Thai food! 

We spent an afternoon wandering around some of the many temples in the old city.  Chiang Mai is very well known for its abundant supply of temples, especially in the old part of the town.  All very impressive, but there does seem to be a lot of focus on who has the biggest, shiniest, most revered golden Buddha effigy, coupled with a subtle sense of wanting in the energy of the place.  Doubt Gautama the Buddha would be impressed with all this idolisation is his name.

We try out a few of the local massage specialties.  First up, J opts for a 1hr massage from the blind at a bargain rate of 150 Bhat.  The lady pretty much just pressed five points on each foot repeatedly for an hour while talking very loudly with the other 6 blind masseuses in the room.  There were no other clients.  The next day we decide to make use of one of the rather dodgy sounding activities listed in the Lonely Planet.  We both visit the Woman's prison for 1 hr traditional massage by inmates! It was the best massage yet and at a very good price.

Chiang Mai's night bazaar, would have to be the best, as well as the streets there are buildings with shops of home decor.  Eager to add to our meagre package waiting to be shipped back home we buy a wooden decorative carving and some large lamps.  It was going to be fun trying to take these back to Bangkok.

5th March is Louisa's birthday, so to celebrate we venture over the road for a nice breakfast then take a rickshaw into town to the markets.  Bit of shopping then find a spa where we both get 2hr treatment including herbal steam, body scrub and aromatherapy massage. 

For dinner we head to Riverside bar and restaurant for their river cruise.  We make our way over the rickety pier, noting that they mustn't have OSH in Thailand.  We were rushed to order food so they could cook it before we set sail.  Then they deliver all three courses at once, including ice cream dessert! Manage to send that back...  Sink a bottle of wine enjoying the sights along the river.  When we arrive back at the pier, we depart and J attempts to take a photo of the boat of L from the wharf.  Leaning against a bamboo balustrade it gives way.  Somehow J manages to avoid tumbling into the river with the camera, impressing the patrons sitting outside who are witnessed the entire event. 

Recapturing our breath we head inside and the restaurant / bar covers band started up with a superb rendition of a Joe Satriani number.  We settle in with another bottle of wine purely to calm those nerves.

Louisa spots girls from the big night out on Koh San Road and they join our table.  By request, the band plays happy birthday and another birthday girl is identified in the audience - 51 year old Sara, a teacher who lives in Chiang Mai, and her three daughters.  Louisa breaks the ice, their table joins ours and the party really gets going. 
Great music from the 2 covers bands including numerous Radiohead songs, the best version J's ever heard of "With or Without You" by U2 (even better than the original he reckons!).. and great rendition of " Little Wing" by Jimi Hendrix.  J almost in heaven.  But they don't know Radiohead "Creep".

At Sara's suggestion, we head to "Bubble", a club a few blocks away.  Dance a couple of hours away to trashy techno and neon strobes.  It seemed the night would never end.

Finally a rickshaw home with the Khoa San Rd girls, who we discovered were staying opposite us.  Louisa befriends a very cute but who-knows-where-its-been dog.

Slightly hungover we meet the girls for breakfast the next morning and spend the rest of the afternoon at the local cafe making use of their wifi before heading off to catch the train back to Bangkok.

Phew glad birthdays only happen once a year, it generally takes a year to get over the last one.

Thankfully we took first class on the way back - the extra room came in handy for all our extra purchases in Chiang Mai.

Minsk to Warsaw - Warsaw, Poland

Jump to the full
entry & travel map
Warsaw, Poland

This morning we got onto the bus and had to say good-bye to Minsk. I'm sure that I'll never make it back to Belarus again, as there are too many places in the world I want to see, but I really enjoyed my brief visit to this picturesque country. As we were driving towards the Polish border, Rhian was not feeling very well, and at our first break of the day he made a mad dash to the bathroom. We had about 20 minutes at the rest stop and some people tried to use of the last of their Belarussian rubbles. David and Rhian had taken out about 50 Euro... and had thousands of rubbles left over. At the rest stop they looked, and they could have purchased a tire if they wanted! For myself, I took out 15 Euro worth of rubbles, and still had a little left over, after buying snack food for the day, about 4 drinks the night before, a metro ticket, and McDonalds!

Our first sightseeing stop this morning was at the Brest Fortress, which was absolutely beautiful. The Brest Fortress is one of the most important Soviet World War II war monuments, commemorating Soviet resistance against the German invasion on June 22, 1941. Approximately 7,000 Soviet military personnel gave their lives over the course of several weeks defending the Fortress, where the resistance "ceased to exist with the building itself". Because of the valiant efforts of the people who gave their lives, the Brest Fortress has been given the status of Hero Fortress, which has only been awarded to a total of twelve Soviet cities. Jenn and I decided to go to the souvenir shop before looking at the Fortress so we could spend the last of our last rubbles. Jenn also needed to buy a bottle of Brest Vodka for her brother-in- law who was originally from Brest. I had 2,500 rubbles left, which is about $1.25, and couldn't figure out what to spend it on. I though perhaps I could buy a bottle or two of beer, and when I wandered to the alcohol counter I saw a bottle of white wine for only 2,400 rubbles... sold! As I was trying to point to the bottle I wanted the lady kept grabbing at the bottles around the one I wanted. Finally when she got my bottle I nodded, and she gave me a look that seemed to be disgust coupled with "how stupid are you?!?" Once back in Canada when I drank the wine I understood the look. The wine tasted like a combination of bad port mixed with rubbing alcohol! After we had our booze, and were out of rubbles, we ran into Tom and walked to the Fortress. We only had about half an hour here, and could have used a lot more time! The memorial is large, and there's a lot to see inside it.

After our short visit we were on our way to the Polish border! Che warned us that this was the worst border crossing of the entire trip, and we had to be prepared for a long wait. The longest he had heard to take crossing the border was 16 hours, and the shortest was 3.5 hours. In Moscow, Galina had arranged for us to meet a Belarussian fellow who was going to help us bribe the right people and get through faster, but it was still anybody's guess at how long it would take. As we were waiting on the bus, Reky decided to start a pool on how long it would take. We had to pay in 50 Euro cent, could choose a ten-minute block. If we crossed the border during that time we won the pot! Pretty much everyone got in on the pool and it helped the time go by. At the border we all had lunch (from the store the day before), and sat outside and chatted. Rhian still wasn't feeling very good... and it was probably a good thing that we had a long border crossing, as he was able to spend a lot of time in the bathrooms! After about 3 hours at the crossing we were all told to get back on the bus, and it looked like we were going to get into Poland in no time at all. Laura V had 3 hours to 3 hours and 10 minutes, and it looked like she was going to win, until we had to turn back to get a road pass. Her time slipped by and Troy was up next. We slowly inched forward, and around 3 hours and 15 minutes we passed into Poland and Troy won the pool! As for myself, I was hoping we would take another hour... but sadly we went through too quickly!

We arrived at Warsaw and checked into our hotel around supper. The hotel in Warsaw was beautiful and I was really impressed! We had an amazing supper that night, and then a group of us went across the street to grab some money from the ATM. When we got back, I wanted to use the Internet quickly, and Jenn showed me to the hotel next door that had a computer. You had to pay for the Internet, but the guy at the front desk didn't have any change, so he let us go on for free! I checked e-mail quickly, and wrote mom a quick message, then Jenn did the same and we headed back to the hotel to wash up before meeting with everyone.

A bunch of us met in the lobby, and headed out to see what there was around the hotel. We walked past the central train station and saw a live band that we listened to for a song or two. Then we headed over to an outdoor bar that had swinging benches and we had a drink there. After the bar some people were heading to "Lemons", but I was in the mood for an 'early' night, and Reky was heading back, so we walked with everyone to the bar, then headed back the long way to the hotel. (I say 'early' because I think it was midnight at that point.) Reky and I chatted the whole way back, and somehow ended up talking about our flaws (I'm too cheerful... he's too protective), and relationships (both have commitment issues), and a bunch of other random topics! Our walk probably took about 45 minutes, but it was a nice relaxing time. Reky is a great guy, and I'd enjoyed getting to know him along the tour.

ESX3 Virtual Disk Modes - Performance, Snapshot and Backup


Hello,

I'm using ESX 3.5 and all our VM's were created with Independent -> Persistent disks because we believe that this was the best practice concerning performance.
Now we wish to backup the .vmdk's files online but in order to do so we need to create snapshots (with the memory option) so that the vmdk can be accessed by the backup software.
I believe that this can only be accomplished by changing the disk mode to snapshot (removing the check from "Independent" in the disk properties of the vm). So my questions are:

1. Is there any other way to backup the files without changing the disk mode?

2. And if we do have to change the disk mode, what effect could that have in the VM's performance? According to this: http://www.vmware.com/pdf/vi_performance_tuning.pdf in page 9 says: "Independent Persistent - Changes are immediately and permanently written to the disk, so they have high performance."

Best Regards
