Aer Lingus’s 48 aircraft carry about 11 million customers a year on 116 routes. The national flag carrier of Ireland operates in a highly competitive market, so it is constantly looking to get as much bang for its buck as possible. For CTO Ravi Simhambhatla, this pressure to keep costs down led him to stop investing in further EMC storage solutions, and instead supplement the loadout with technology from Tegile.
“It came down to three words: price/performance ratio,” says Simhambhatla. “We have IBM in-house, we have EMC in-house, but when I look at long-time viability in terms of performance ratio, they simply don’t match Tegile.”
Simhambhatla has spent about £330,000 on an 80TB Zebi HA2800 storage array, and is using this to support an entire virtual infrastructure.
“We’ve got corporate file shares, 80 virtual machines, we’re replacing 1,400 desktops with virtual desktops, and all the storage is going to be residing with Tegile,” says Simhambhatla.
“And we’re going to start migrating Microsoft Exchange across the Tegile environment as well,” he adds.
Simhambhatla says Tegile’s proprietary compression method is paying dividends.
“The performance is fantastic,” he says.
“We implemented our VDI strategy in quarter one of 2013 – migrating away from desktop and laptop environments. We would not have done it unless we were absolutely sure of the Tegile performance.
“My guys are very impressed with the compression. When we moved the corporate fileshare to the Tegile from the EMC systems, we’d taken 4.7TB, which translated to 1.7TB on the Tegile, because of the level of compression.
“The speed of compression and decompression in the Flash is not even perceptible. So when we moved the fileshares, nobody in the company knew.”
Tegile president of EMEA Paul Silver puts the compression level down to the firm’s “secret sauce” – the way its solutions deal with the metadata layer.
“It’s usually a big overhead on the IO, and that’s why other vendors have not been able to [match our layer of compression]; because they can’t figure out the duplication over the hard disk – but we took the metadata off the hard disk, and put it on its own dedicated solid state drive. That drive’s mirrored and copied for resilience. And so it’s in one place, instantly available, and is very fast,” he explains.
