FOR IMMEDIATE RELEASE

Xyratex Ltd Announces Results for the Fourth Quarter and Fiscal Year 2011

Havant, UK, January 5, 2012—Xyratex Ltd. (Nasdaq: XRTX), a leading provider of enterprise class data storage subsystems and hard disk drive capital equipment, today announced results for the fourth quarter and fiscal year ended November 30, 2011.  Revenues for the fourth quarter were $387.6 million, a decrease of 2.3% compared to revenues of $396.8 million for the same period last year.

For the fourth quarter, GAAP net income was $18.5 million, or $0.65 per diluted share, compared to GAAP net income of $32.3 million, or $1.02 per diluted share, in the same period last year. Non-GAAP net income was $20.8 million, or a diluted earnings per share of $0.73, compared to non-GAAP net income of $21.9 million, or $0.69 per diluted share, in the same quarter a year ago(1).

Gross profit margin in the fourth quarter was 17.7%, compared to 16.1% in the same period last year and 16.7% in the prior quarter. The change from the prior quarter was primarily due to a higher gross margin for Storage Infrastructure (SI) products.

Revenues from sales of our Networked Storage Solutions (NSS) products were $352.6 million in the fourth quarter as compared to $326.8 million in the same quarter a year ago, an increase of 8%. Gross profit margin for NSS products in the fourth quarter was 17.7% as compared to 13.3% in the same quarter a year ago due to favorable changes in customer and product mix. Revenues from sales of our SI products in the fourth quarter were $35 million as compared to $70 million in the same quarter a year ago, a decrease of 50%. Gross profit margin in the SI business in the fourth quarter was 18.0% as compared to 29.7% in the same quarter a year ago, primarily due to the decrease in revenues relative to fixed costs.

Revenues for fiscal year 2011 were $1,448.5 million, a decrease of 9.6% compared to revenues of $1,601.9 million for fiscal year 2010. Revenues from sales of our NSS products were $1,324.5 million for the year as compared to $1,258.9 million in fiscal 2010, an increase of 5.2%. Revenues from sales of our SI products in fiscal 2011 were $123.9 million as compared to $342.9 million in 2010, a decrease of 63.9%. Gross profit margin for fiscal 2011 was 15.3% compared to 17.5% in the previous year. The decrease in gross profit margin from the prior year was primarily due to the decrease in SI revenues, partially offset by increased gross margins for NSS products related to favorable changes in customer and product mix.

GAAP net income for fiscal 2011 was $28.3 million, or $0.92 per diluted share, compared to GAAP net income of $139.4 million, or $4.46 per diluted share, for fiscal 2010. Non-GAAP net income for fiscal 2011 decreased to $39.0 million, or $1.27 per

2

diluted share, compared to non-GAAP net income of $135.7 million, or $4.34 per diluted share, for fiscal 2010(1).

During the quarter, the Company repurchased 986,707 of its common shares at a total cost of $8.4 million. For the full fiscal year, the Company repurchased a total of 3,601,903 shares, representing 11.6% of issued and outstanding shares as of February 28, 2011, at a total cost of $32.3 million. The shares were repurchased under the previously announced share repurchase plan. Also, the Company announced its second dividend in the quarter. The cash dividend was set at $0.055 a share. The Company’s cash balance was $132.6 million at the end of the fiscal year, an increase of $41.8 million during the 2011 fiscal year.

“Overall, I am pleased with our results for the fiscal year. Our NSS business had a very good year as a result of good execution and a more diverse customer base. The Enterprise Storage market is strong, and we did a very good job in meeting the technology requirements and demands of our customer base. Our SI business results reflect the many challenges that affected the wider Hard Disk Drive industry in 2011, including reduced capital expenditures resulting from delays in regulatory approvals for the two acquisitions by Seagate and Western Digital, the two natural disasters in Japan and Thailand, and increased competition. As a result of the reduction in capital expenditures by our customers, we took decisive cost reduction actions in the SI business to better align our cost structure with our business expectations,” said Steve Barber, CEO of Xyratex. “Looking forward, I believe we are well positioned to capitalize on the many business opportunities that we have been working on, including our entry into the High Performance Computing storage market. We believe that this, together with cost realignment within the business, provides us with a good opportunity to improve our profitability and continue our cash generation.”

Business Outlook

The following statements are based on current expectations. These statements are forward-looking, and actual results may differ materially. Our forecast ranges are wider than normal due to the uncertainty surrounding disk drive availability following the recent flooding in Thailand.

·                  Revenue in the first quarter of fiscal 2012 is projected to be in the range of $275 million to $355 million.

·                  Fully diluted earnings (loss) per share is anticipated to be between $(0.02) and $0.32 on a GAAP basis in the first quarter. On a non-GAAP basis, fully diluted earnings per share is anticipated to be between $0.07 and $0.41. Non-GAAP earnings per share excludes amortization of intangible assets, equity compensation expense, specified non-recurring items and related taxation expense.

Conference Call/Webcast Information

The company will host a conference call to discuss its results at 1:30 p.m. PT/4:30 p.m. ET on Thursday, January 5, 2012.

The conference call can be accessed online via the company’s website www.xyratex.com/investors, or by telephone as follows:

A replay will be available via the company’s website www.xyratex.com/investors, or can be accessed by telephone through January 12, 2012 as follows:

(1) Non-GAAP net income and diluted earnings per share exclude (a) amortization and impairment of intangible assets, (b) equity compensation expense, (c) specified non-recurring items, such as the release of the valuation allowance against a deferred tax asset and the reduction in acquisition deferred consideration, (d) the tax effects related to (a) through (c), and (e) the tax expense resulting from a reduction in the deferred tax asset caused by a fall in U.K. tax rates. Reconciliation of non-GAAP net income and diluted earnings per share to GAAP net income and GAAP diluted earnings per share is included in a table immediately following the condensed consolidated statements of cash flow below.

The intention in providing these non-GAAP measures is to provide supplemental information regarding the Company’s operational performance while recognizing that they have material limitations and that they should only be referred to with reference to, and not considered to be a substitute for, or superior to, the corresponding GAAP measure. The financial results calculated in accordance with GAAP and reconciliations of these non-GAAP measures to the comparable GAAP measures should be carefully evaluated. The non-GAAP financial measures used by us may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies.

The Company believes that the provision of these non-GAAP financial measures is useful to investors and investment analysts because it enables comparison to the Company’s historical operating results, those of competitors and other industry participants and also provides transparency to the measures used by management in operational and financial decision making. In relation to the specific items excluded: (a) intangible assets represent costs incurred by the acquired business prior to acquisition, are not cash costs and will not be replaced when the assets are fully amortized and therefore the exclusion of these costs provides management and investors with better visibility of the costs required to generate revenue over time; (b) equity compensation expense is non-cash in nature and is outside the control of management during the period in which the expense is incurred; (c)

4

the release of the valuation allowance against a deferred tax asset and the reduction in acquisition deferred consideration are non-cash and not comparable across periods or with other companies; (d) the exclusion of the related tax effects of excluding items (a) through (c) is necessary to show the effect on net income of the change in tax expense that would have been recorded if these items had not been incurred and (e) the impact of the reduction in tax rates is non-cash and not comparable across periods or with other companies due to the existence of a significant U.K. related deferred tax asset that is expected to reduce over time.

Safe Harbor Statement

These statements relate to future events or our future financial performance, including our projected revenue and fully diluted earnings (loss) per share data (on a GAAP and non-GAAP basis) for the first quarter of fiscal year 2012. These statements are only predictions and involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to differ materially from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements.

These risks and other factors include those listed under “Risk Factors” and elsewhere in our Annual Report on Form 20-F as filed with the Securities and Exchange Commission (File No. 000-50799).
