Equallogic Latest Release: Firmware V5.1.2, SANHQ 2.2, HIT/VMware 3.1.1

No more worries using the pre-released or pre-production versions. As usual, it’s recommended to wait for at least another month before upgrade to the latest firmware.

I am going to try the latest SANHQ and HIT/VMware this week for sure.

Equallogic PS Series Firmware, version V5.1.2
Enhanced Load Balancing, VSSA and Thin Provision Stun

SANHQ 2.2
Live View and 95th Percentile Reporting, as well as RAID Evaluator (ie, R10 > R50 performance prediction)

HIT/VMware 3.1.1
Support for VMware Version 5, VMFS 5, Thin Provision Stun, VASA, Datastore Clusters and Storage DRS

Finally, I also noticed the release of a newer version of EqualLogic Multipathing Extension Module (MEM) V1.0.1

 

Update: Oct 27, 2011

I’ve upgraded the SANHQ to version 2.2 and immediately tried two of the most interesting features,

1. Live View

live_view

It does provide very useful detail ONLY when you need it, such as when you suddently found IOPS is abnormal and wanted to find out which volume is causing the problem. However to be honest, I would rather use VMTurbo’s Usage for VM table, it’s much easier and easy to find the bad VMs.

2. RAID Evaluator

raid_eval

I found this is the most useful one in my own environment as I may expand my Equallogic SAN capacity by changing from RAID10 to RAID50, so I definitely need to know the estimated  performance decrease if I do so, it shows me 41%, wow, that’s huge!

 

I recevied a false alarm email with subject “SAN HQ Notification Alert” immediately after the SANHQ upgrade completed

Caution conditions:

10/27/2011 9:02:44 PM to 10/27/2011 9:08:08 PM

Autoart: Pagani Huayra Coming Soon, God Knows When!

huayra

A fter seven years of hard work I am now able to tell you a little brief history and the path that led to the birth of the Huayra, project name C9.

The concept was born in 2003, the year of the introduction of the Zonda S Roadster. As you may recall the early 2000s were prosperous for the world of supercars. The commitment of big car manufacturers have contributed to the rise of extraordinary cars like the Bugatti Veyron, Porsche Carrera GT, Ferrari Enzo, Mercedes McLaren SLR.

This context led us to make several observations concerning the future of the Zonda and what could be a new Pagani. Since the original design of the Zonda was done in the early 90s the first thought was that it was now an obsolete project and we decided to imagine the car totally different in form, dimension, dynamics and technology, all this without losing the essence of our approach, to follow a concept born in the Renaissance where Leonardo da Vinci told us that art and science are disciplines that need to walk alongside. The eternal element air in all its forms, especially wind, became determining in defining the concept and it was a great inspiration, a sit is ever present in our lives: a jet turbine, the silence of a glider… the elegance of the movements the wind creates&hellip but also the violence and force that it can unleash.

The Huayra is made of more than 4000 components (engine and gearbox not included). To create them and put them together requires creativity, patience and passion that I shared with a fantastic young team and with the most competent partner in all sectors.

In defining the size, I immediately thought of a car that would be longer than the Zonda, a track increased by 70 mm, a cabin position shifted 40 mm to the back and even more spacious. The silhouette should be soft, easy to read and form itself from lean and sleek lines that have a clear beginning and an end.

As the style is concerned during these five years we have tried to find the best compromise working on 8 scale models and 2 full scale models, as well as hundreds of drawings without never leaving the original idea and taking meticulous care of the details.

The ideas were of including elliptical shapes reminding of our brand in the front and at the back, keeping the central exhaust as the completion of the line of the canopy, the line starting at the headlight area that continues and ends into the air intake. We also thought from the beginning of active aerodynamics. Flaps that are activated according to the study of results gathered through calculations and aerodynamic testing. The whole car is shaped as a wing so it was necessary to create a high front to reduce the length of the upper part of this wing to counteract lift.

The active suspension in the front and the 4 flaps allow to optimally balance the drag coefficient and downforce.

Mercedes-AMG has created a truly unique and lightweight engine, a twin turbo with over 700 HP and 1100 Nm of torque that perfectly complements the car giving a feeling that has motivated our research: that of the brute force of an airplane taking off.

The main focus was in a power delivery that was linear and not with lag, because that could potentially create safety problems or a continuous operation of electronic driving aids.

Mercedes-AMG already 5 years ago thought about the coming environmental restrictions by creating a 12-cylinder engine that is at the peak of efficiency in terms of CO2 and consumption.

Pirelli has created a very progressive tyre with a exceptional grip in all situations and with low rolling friction. Every aspect of safety was treated taking into account the dynamic by which most accidents with high performance rear engined cars occur.

While developing the C9 we witnessed the evolution of the different models of the Zonda and it showed us that the Zonda wasn’t obsolete as I had originally feared. The Zonda R has been a key laboratory for the Huayra. The team was able to work on many projects at the same time driving on different tracks that occasionally came to meet by sharing engineering concepts, materials, safety and scientific or design studies.
