1. World of HELIOS: Spotlight search performance In a meeting with a customer last week, we discussed HELIOS UB2
Spotlight searches of full text and metadata in server files.
I explained that our searches are always quick, with search results
usually displayed immediately within the Mac Finder, Windows Explorer,
WebShare or “dt” command line. At the customer’s installation
they use a 16 TB storage system where searches took about 30
seconds; repeating the search yielded immediate results. We traced
the search and figured out that the index server responds immediately
– however verifying the resulting files took 30 seconds. The
delay was due because the disk cannot seek as fast as we find
results. The second search was without delay because all accessed
file entries had just been cached by the operating system.
With today’s large terabyte storage systems, we have to remember
that the disk seeking performance has not changed much over the
last two decades, it is still about several milliseconds long.
A RAID will stripe data with excellent sequential performance.
However, for random reads, the RAID seeking performance will be
slower because it has to wait for all disks in a RAID group to
Let’s compare options. Say the initial Spotlight search might
be 1-30 seconds. Looking at alternatives, a UNIX ‘find’ would
take many hours to find the same results. Searching using non-Spotlight
connections, e.g. via SMB connected volumes from a Mac, would
take days. So the Spotlight search introduced in HELIOS UB2 is
orders of magnitude faster.
2. HELIOS earns new FograCert soft proof certifications The WebShare + PrintPreview UB2 proofing solution received three
new certifications for soft proofing using the Eizo CG245W and
CG275W proof monitors. The distinctive feature of these proofing
monitors is that they include a built-in measurement device within
the monitor, so third-party calibration devices are not required.
The CG245 has also been certified using the X-Rite i1-Pro measurement
device. More information about the FograCert softproofing system
is available at: http://www.fogra.org/en/fogra-fogracert-en/prepress/softproof-/softproofing-system/softproofing-system.html.

later refered as “combis”) to be certified
3. Fogra's Color Management Symposium About 250 visitors attended the recent Fogra Color Management
Symposium in Munich, Germany. Very interesting presentations covered
many diverse topics about color management. In particular, there
are two interesting topics we would like to share with you.
1) Optical brighteners used in printing papers lead to different appearances depending
on the amount of UV light included in the viewing and measuring
condition. Sunlight includes UV light, however most existing light
booths must be upgraded to include the new standard for UV light.
The same is true for most color measurement devices which may
not include the proper amount of UV light for measuring color.
2) Tele-measuring for the softproof means instead of measuring the monitor color
directly on the display panel or the printing color directly on
the paper, the color is measured from a short distance, to include
the viewing light environment. This is how the FograCert Softproof
certification is performed. New measurement devices will allow
Tele-measuring which will lead to more accurate results. Watch
for the next HELIOS Newsletter for advice on how to achieve perfectly
4. HELIOS UB2 supports server virtualization using VMware
ESXi 5 In addition to existing support for ESX Server 3 and 4, HELIOS
UB2 supports VMware ESXi 5. This completes the server virtualization
support. All major server virtualization vendors – Microsoft
Hyper-V, VMware ESX Server, Linux Xen and Citrix XenServer –
are fully supported. HELIOS solutions support Linux, Windows and
Solaris as the guest operating system on top of the VM server
solutions. The HELIOS MachID is supplied via a virtual machine
ID (without a USB dongle) which means it supports VM high availably
and load balancing. We know that many customers are deploying
virtual servers – doing so with HELIOS UB2 is fully supported.
