Flash memory solutions provider Fusion-io has its IPO lurking just around the corner, and is getting a lot of attention from investors already. The most recent proof of that is that the company has increased the pricing of its shares for the second time, from $16 to $18 per share. This brings Fusion-io’s valuation to up to $1.4 billion, compared with $1.17 billion at the first price range.

“Fusion-io is planning to sell 10,755,607 shares in the offering; and current stockholders will be offering 1,544,393 shares as well. The company plans to raise as much as $254.6 million (up from $212 million a few weeks ago)…”

The company will begin trading under the symbol of “FIO.”

In the previous update to its SEC filing, Fusion-io shed some light on its earnings and customer base, as well as IPO intentions. The hardware acceleration solutions provider turned profitable not too long ago, and names Facebook and Apple as its top customers. At present, its top 10 biggest customers account for over 90 percent of sales.

Fusion-io raised a total of $110 in capital from big name VC ‘s such as Andreessen Horowitz and Accel partners. Competitor Violin Memory – led by Don Basile, a former chairman and CEO of Fusion-io — seems to be following its footsteps, and closed a $40 million Series C funding round. Violin, currently evaluated at about $440 million, sells flash-based memory arrays designed to replace hard-disk alternatives, rather than offering “add ins” designed to accelerate servers.

IPO season has definitely begun, and more and more tech companies seems to be jumping aboard. One of the most recent developments is telecommunications gear maker Avaya, which reportedly plans to file for a $1 billion IPO as early as next week. The offering is estimated to raise the company’s valuation to $5 billion, or 40 percent less than the $8.2 billion TPG Capital and Silver Lake Partners paid to take it private four years ago.
