Memory boost
gives 9x7s performance leap
Vaske Computer installs, supports 1.5Gb to help forestall
software upgrade fees
Massive installations of memory in older HP 3000s are
delivering performance increases that can forestall upgrades
and the associated software upgrade fees.
Owners of Series 9x7 HP 3000s are reporting theyve
installed up to 1.5Gb of memory in the systems, reducing run times by
a process offered by Vaske Computer Solutions. The integration and
support firm has assisted several credit unions using the Summit
Information Systems Spectrum software in making the memory upgrade,
including City County Credit Union of St. Paul, Minn., Royal Credit
Union of Eau Claire, Wisc., and Founders Federal Credit Union of
Lancaster, S.C.
HP only officially supports up to 384Mb of RAM on the 9x7
series, so VP of Information Systems Marc Kilgore had to go somewhere
else for hardware support. He chose Vaske Computer Solutions
(612.844.0054), a company that supports HP 3000 shops in the
Minnesota, Wisconsin, Iowa, and Northern Illinois areas from offices
in Minneapolis and Madison, WI. Vaske uses subcontractors to service
other locations throughout the country on a custom basis.
Kilgore said he was considering upgrading his Series 967 to
a Series 987/200, or going to a 9x9 Series 3000. We kept
looking, and [Vaske] said theyd be willing to load up our 967
with 1.5Gb of memory, which we didnt even know could be done.
They said if we didnt see a difference, they would take it back
out and not charge us for a thing. How could I go
wrong?
Buying enough memory to take his system from 512Mb to 1.5Gb
wasnt cheap. But Kilgore said it was cheaper than the purchase
of a new system and the cost of upgrading software on a higher 3000
software tier.
The memory was kind of spendy, to get those high
density chips, about $40,000 to $50,000, he said. But we
didnt have to pay for any software upgrades, and I think
weve got another year or two of life in this box. HP has
set an end of support date for the 9x7 Series of April,
2002.
Kilgore estimated his software maintenance fees would have
increased by $35,000 for each year if the credit union had purchased
an upgraded HP 3000 Series 987/200. And if wed gone with
a 9x9 system, the upgrade fees would have been double that, he
said.
As a credit union that serves 35,000 members, City
Countys month-end cycle is very intensive, with big batch
processes that have serial reads on huge databases, Kilgore
said. It was immediately apparent after a couple of hours at
that time that it made a dramatic difference. Jobs that ran
12-14 hours long only took four hours to complete.
Some jobs would do huge serial reads, and before the
upgrade, wed see a tremendous amount of IO, Kilgore said,
disks just churning away. The first time we looked at it after
the memory upgrade, we saw five times the number of IOs before, and
then no IO traffic. It loads the whole dataset into memory now,
without having to do all those IOs. Its really dramatic, and we
didnt expect it to be that good.
The credit union also installed new disk arrays and Mirrored
Disk/iX, to make its total outlay for the project about $80,000. But
Kilgore attributed the majority of the speed increase to the new
memory installed. To me, it was like a free upgrade, he
said.
John Lee of Vaske Computer said the process is not
inexpensive, but its not nearly as expensive as upgrading
hardware and software tiers. You can significantly increase the
performance of your 9x7 system by absolutely loading it to the max
with memory, and then controlling how it is used. Lee said in
one case, response time decreased by a factor of 6.
Well let the site use the memory for seven days,
and if they are not satisfied with the performance increase,
well deinstall it and put back in their original
configuration, he said. Strategic Memory Systems is the
memory manufacturer, but we do all the work. To date, no one has had
us deinstall the memory, because performance improves
dramatically.
Summit provides all MPE/iX operating system support for the
City County credit union, Kilgore said, and while the vendor told him
the memory upgrade was a foolish idea, it continues to
support the configuration with the new memory installed. The credit
union dropped HP hardware support some time ago, when we got
frustrated with HP. To me, this has already paid for itself. Any [9x7
site] would be foolish not to do this. |
